PROXY STATEMENT

PROXIES AND VOTING AT THE MEETING

Only shareholders of record at the close of business on March 13, 2013 will be entitled to notice of, and to vote at, the meeting. As of that date, 108,195,457 shares of our Common Stock, $0.25 par value per share (“Common Stock”), were outstanding. Each of those outstanding shares is entitled to one vote at the meeting. We are initially sending this Proxy Statement and the accompanying proxy to our shareholders on or about March 25, 2013. The requirement for a quorum at the meeting is the presence in person or by proxy of holders of a majority of the outstanding shares of Common Stock. There is no provision for cumulative voting.

Solicitation of Proxies

The accompanying proxy is solicited on behalf of our Board of Directors for use at our annual meeting of shareholders to be held at the time and place set forth in the accompanying notice. We will pay all costs of soliciting proxies. We will solicit proxies primarily by mail.

We have retained Georgeson Shareholder Communications, Inc. to solicit proxies at a fee estimated at $9,000, plus out-of-pocket expenses. We will reimburse brokerage firms, banks and other custodians, nominees and fiduciaries for their reasonable expenses in forwarding proxy material to beneficial owners of our Common Stock.

The persons named as proxies were designated by our Board and are officers of Oceaneering. All properly executed proxies will be voted (except to the extent that authority to vote has been withheld), and where a choice has been specified by the shareholder as provided in the proxy, the proxy will be voted in accordance with the specification so made. Proxies submitted without specified choices will be voted FOR Proposal 1 to elect the director nominees proposed by our Board, FOR Proposal 2 to cast an advisory vote on a resolution to approve the compensation of Oceaneering’s Named Executive Officers, and FOR Proposal 3 to ratify the appointment of Ernst & Young LLP as independent auditors of Oceaneering for the year ending December 31, 2013.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Certificate of Incorporation divides our Board into three classes, each consisting as nearly as possible of one-third of the members of the whole Board. There are currently three directors of Classes II and III, and two directors of Class I. The members of each class serve for three years following their election, with one class being elected each year.

Two Class III directors are to be elected at the 2013 Annual Meeting. As previously announced, David S. Hooker, currently a Class III director, is retiring from the Board concurrently with the election of Class III directors at the 2013 Annual Meeting. Accordingly, the Board determined to reset the number of directors comprising Class III to two.

In accordance with our bylaws, directors are elected by a plurality of the votes cast. However, we amended our Corporate Governance Guidelines on May 4, 2012 to provide that, in an uncontested election of directors, any director nominee who does not receive a “for” vote by a majority of shares present in person or by proxy and entitled to vote and actually voting on the matter shall promptly tender his or her resignation to the Nominating and Corporate Governance Committee of Oceaneering’s Board, subject to acceptance by the Board. The Nominating and Corporate Governance Committee will then make a recommendation to the Board with respect to the director’s resignation and the Board will consider the recommendation and take appropriate action within 120 days from the date of the certification of the election results. Abstentions and broker “non-votes” marked on proxy cards will not be counted in the election.

The Class III directors will serve until the 2016 Annual Meeting of Shareholders or until a successor has been duly elected and qualified. The directors of Classes I and II will continue to serve their terms of office, which will expire at the Annual Meetings of Shareholders to be held in 2014 and 2015, respectively.

The persons named in the accompanying proxy intend to vote all proxies received in favor of the election of the nominees named below, except in any case where authority to vote for the directors is withheld. Although we have no reason to believe that the nominees will be unable to serve as directors, if any nominee withdraws or otherwise becomes unavailable to serve, the persons named as proxies will vote for any substitute nominee our Board designates.

Set forth below is information (ages are as of April 26, 2013) with respect to the two nominees for election as Class III directors of Oceaneering, Paul B. Murphy, Jr. and Harris J. Pappas. Mr. Murphy was appointed to the Board following the enlargement of the Board in August 2012.

CORPORATE GOVERNANCE

During 2012, our Board of Directors held eight meetings of the full Board and 20 meetings of the committees of the Board. Each director attended at least 75% of the aggregate number of meetings of the Board and meetings of the committees of the Board on which he served. In addition, we have a policy that directors are encouraged to attend the annual meeting. Last year, all of our directors attended our annual meeting. In 2012, the nonemployee directors met in regularly scheduled executive sessions without management present, and similar sessions are scheduled for 2013. The chairmen of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee chair these executive sessions on a rotating basis. Interested parties may communicate directly with the nonemployee directors by sending a letter to the “Board of Directors (independent members),” c/o Corporate Secretary, Oceaneering International, Inc., 11911 FM 529, Houston, Texas 77041-3000.

Under rules adopted by the New York Stock Exchange (the “NYSE”), our Board of Directors must have a majority of independent directors. The director independence standards of the NYSE require a board determination that our director has no material relationship with us and has no specific relationships that preclude independence. Our Board of Directors considers relevant facts and circumstances in assessing whether a director is independent. Our Board of Directors has determined that the following directors meet the NYSE independence requirements: Jerold J. DesRoche; D. Michael Hughes; David S. Hooker; Paul B. Murphy, Jr.; and Harris J. Pappas. Our Board does not believe that M. Kevin McEvoy (our Chief Executive Officer), T. Jay Collins (our former Chief Executive Officer) or John R. Huff (our Chairman of the Board and former Chief Executive Officer) is independent under the NYSE independence standards.

We have three standing committees of our Board of Directors: the Audit Committee; the Compensation Committee; and the Nominating and Corporate Governance Committee. Our Board of Directors has determined that each member of these committees is independent in accordance with the requirements of the NYSE. Our Board has also determined that each member of the Audit Committee meets the independence requirements for service on an audit committee that the SEC has established.

COMMITTEES OF THE BOARD

The Audit Committee

The Audit Committee, which is comprised of Messrs. Hooker (Chairman), Hughes, Murphy, and Pappas, held 11 meetings during 2012. Our Board of Directors intends to appoint a new Chairman of the Audit Committee, from among the existing members of the Audit Committee, following Mr. Hooker’s retirement. Our Board of Directors has determined that all members of the Audit Committee are audit committee financial experts as defined in the applicable rules of the SEC. For information relating to the background of each continuing member of the Audit Committee, see the biographical information under “Information about Nominees for Election and Continuing Directors.” The Audit Committee is appointed by our Board of Directors, on the recommendation of the Nominating and Corporate Governance Committee, to assist the Board in its oversight of:

• the integrity of our financial statements;

• our compliance with legal and regulatory requirements;

• the independence, qualifications and performance of our independent auditors;

• the performance of our internal audit functions; and

• the adequacy of our internal control over financial reporting.

Our management is responsible for our internal controls and preparation of our consolidated financial statements. Our independent auditors are responsible for performing an independent audit of the consolidated financial statements and internal controls over financial reporting and issuing reports thereon. The Audit Committee is responsible for overseeing the conduct of these activities and appointing our independent auditors. As stated above and in the Audit Committee Charter, the Audit Committee’s responsibility is one of oversight. The Audit Committee is not providing any expert or special assurance as to Oceaneering’s financial statements or any professional certification as to the independent auditors’ work.

In discharging its duties, the Audit Committee reviews and approves the scope of the annual audit, non-audit services to be performed by the independent auditors and the independent auditors’ audit and non-audit fees; reviews and discusses with management (including the senior internal auditor) and the independent auditors’ annual audit of our internal control over financial reporting; recommends to our Board of Directors that the audited financial statements be included in the Annual Report on Form
10-K for filing with the SEC; meets independently with our internal auditors, independent auditors and management; reviews the general scope of our accounting, financial reporting, annual audit and our internal audit programs and matters relating to internal control systems, as well as the results of the annual audit and interim financial statements, auditor independence issues and the adequacy of the Audit Committee charter; and reviews with management and the independent auditors any correspondence with regulators or governmental agencies and any published reports that raise material issues regarding our financial statements or accounting policies. A copy of the Audit Committee charter is available on the Corporate Governance page in the Investor Relations section of our Web site (www.oceaneering.com). Any shareholder may obtain a written copy of the charter from us upon request. The report of the Audit Committee is included in this Proxy Statement under the heading “Report of the Audit Committee.”

Specific duties and responsibilities of the Compensation Committee include: overseeing our executive and key employee compensation plans and benefit programs; reviewing and approving objectives relevant to the compensation of executives and key employees, including administration of annual bonus plans, long-term incentive plans, supplemental executive retirement plan and severance, termination and change-of-control arrangements; approving employment agreements for key executives; reviewing and making recommendations to the Board regarding the directors’ and officers’ indemnification and insurance matters; evaluating the performance of executives and key employees, including our Chief Executive Officer; recommending to the Board the compensation for the Board and committees of the Board; and annually evaluating its own performance and its charter.

Since 2004, the Compensation Committee has engaged Mercer, a nationally recognized human resource consulting firm, to assist the Compensation Committee in its administration of compensation for our executive officers. Mercer assisted the Compensation Committee in the design and particulars of our existing long-term incentive program. Mercer performed a market analysis of total direct compensation (the sum of salary, annual incentive bonus and long-term incentive compensation) and retirement plan value for our executives and other key employees and compensation for nonemployee directors among peer group companies and other survey data (see “Compensation Discussion and Analysis – The Role of the Compensation Consultant” in this Proxy Statement). The Compensation Committee approved the form and amounts of our 2012 long-term incentive program and compensation for our executive officers and other key employees, and recommended to the Board the forms and amounts of compensation for nonemployee directors.

A copy of the Compensation Committee charter is available on the Corporate Governance page in the Investor Relations section of our Web site (www.oceaneering.com). Any shareholder may obtain a written copy of the charter from us upon request. The report of the Compensation Committee is included in this Proxy Statement under the heading “Report of the Compensation Committee.”

The Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee, which is comprised of Messrs. Hughes (Chairman), DesRoche and Hooker, held four meetings during 2012. The Nominating and Corporate Governance Committee is appointed by our Board of Directors to:

• identify individuals qualified to become directors of Oceaneering;

• recommend to our Board candidates to fill vacancies on our Board or to stand for election to the Board by our shareholders;

• recommend to our Board a director to serve as Chairman of the Board;

• recommend to our Board committee assignments for directors;

• periodically assess the performance of our Board and its committees;

• periodically review with our Board succession planning with respect to our Chief Executive Officer and other executive officers;

• evaluate related-person transactions in accordance with our policy regarding such transactions; and

• periodically review and assess the adequacy of our corporate governance policies and procedures.

The Nominating and Corporate Governance Committee operates under a written charter adopted by our Board of Directors. A copy of this charter and a copy of our Corporate Governance Guidelines are available on the Corporate Governance page in the Investor Relations section of our Web site (www.oceaneering.com). Any shareholder may obtain a written copy of each of these documents from us upon request.

The Nominating and Corporate Governance Committee solicits ideas for potential Board candidates from a number of sources, including members of our Board of Directors and our executive officers. The Committee also has authority to select and compensate a third-party search firm to help identify candidates, if it deems it advisable to do so.

The Nominating and Corporate Governance Committee will also consider nominees recommended by shareholders in accordance with our bylaws. In assessing the qualifications of all prospective nominees to the Board, the Nominating and Corporate Governance Committee will consider, in addition to criteria set forth in our bylaws, each nominee’s personal and professional integrity, experience, skills, ability and willingness to devote the time and effort necessary to be an effective board member, and commitment to acting in the best interests of Oceaneering and its shareholders. Consideration also will be given to the Board’s diversity and having an appropriate mix of backgrounds and skills. In that regard, our Corporate Governance Guidelines provide that any search for potential director candidates should consider diversity as to gender, ethnic background and personal and professional experiences.

A shareholder who wishes to recommend a nominee for director should comply with the procedures specified in our bylaws, as well as applicable securities laws and regulations of the NYSE. The Nominating and Corporate Governance Committee will consider all candidates identified through the processes described above, whether identified by the Committee or by a shareholder, and will evaluate each of them on the same basis.

As to each person a shareholder proposes to nominate for election as a director, our bylaws provide that the nomination notice must:

• include the name, age, business address and principal occupation or employment of that person, the number of shares of Common Stock beneficially owned or owned of record by that person and any other information relating to that person that is required to be disclosed under Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the related SEC rules and regulations; and

• be accompanied by the written consent of the person to be named in the proxy statement as a nominee and to serve as a director if elected.

The nomination notice must also include, as to that shareholder and the beneficial owner, if any, of Common Stock on whose behalf the nomination or nominations are being made:

• the name and address of that shareholder, as they appear on our stock records and the name and address of that beneficial owner;

• the number of shares of Common Stock which that shareholder and that beneficial owner own beneficially or of record;

• a description of all arrangements and understandings between that shareholder or that beneficial owner and each proposed nominee of that shareholder and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by that shareholder;

• a representation by that shareholder that he or she intends to appear in person or by proxy at that meeting to nominate the person(s) named in that nomination notice;

• a representation as to whether that shareholder or that beneficial owner, if any, intends, or is part of a group, as Rule 13d-5(b) under the Exchange Act uses that term, which intends (1) to deliver a proxy statement and/or form of proxy to the holders of shares of Common Stock having at least the percentage of the total votes of the holders of all outstanding shares of Common Stock entitled to vote in the election of each proposed nominee of that shareholder which is required to elect that proposed nominee and/or (2) otherwise to solicit proxies in support of the nomination; and

• any other information relating to that shareholder and that beneficial owner that is required to be disclosed under Section 14 of the Exchange Act and the related SEC rules and regulations.

To be timely for consideration at our 2014 Annual Meeting, a shareholder’s nomination notice must be received at our principal executive offices, 11911 FM 529, Houston, Texas 77041-3000, addressed to our Corporate Secretary, not earlier than October 28, 2013 and not later than the close of business on December 27, 2013.

LEADERSHIP STRUCTURE AND BOARD RISK OVERSIGHT

We currently have a leadership structure that includes separate individuals serving as our Chief Executive Officer and Chairman of the Board. Our Board believes this structure is appropriate in the existing circumstances, as Messrs. McEvoy and Huff, our Chief Executive Officer and Chairman of the Board, respectively, currently serve our company in separate and distinct roles. Our Board believes it is appropriate to retain the flexibility to combine those two positions in the future, should future circumstances result in a situation in which our Board determines that such a combination is appropriate.

The members of each of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee include only persons whom the Board has affirmatively determined are independent. Accordingly, none of Messrs. McEvoy, Collins and Huff is a member of any of those Board committees. None of the Chairmen of our Board committees serves as Chairman of more than one of those committees. As discussed above, our Board of Directors has determined that all members of the Audit Committee are audit committee financial experts as defined in the applicable rules of the SEC. Although our Board believes the current membership and leadership structure for our Board committees are appropriate in the existing circumstances, our Board also believes it is appropriate to retain the flexibility to change Board committee memberships and leadership in the future, should future circumstances warrant such a change in the view of our Board.

Our Board oversees our financial-related risks primarily through the Audit Committee and our risks associated with compensation policies and practices for executive officers and key employees primarily through the Compensation Committee. Our Compensation Committee considers, in establishing and reviewing compensation programs, whether the programs encourage unnecessary or excessive risk taking. Based on analyses conducted by management and discussed with the Compensation Committee, we do not believe that our compensation programs for our executives and other employees are reasonably likely to have a material adverse effect on us. Our Board believes that the current structure of our Audit Committee, with all members being independent and audit committee financial experts, and our Compensation Committee, with all members being independent, provides for an efficient and effective means of overseeing these risks. Our Board oversees our strategic and operations-related risks through the entire Board. Our Board believes that the relative levels of experience and independence of our Board members, collectively, support the Board’s ability to effectively oversee these risks at the entire Board level.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

No member of the Compensation Committee has served as one of our officers or employees at any time. None of our executive officers serves as a member of the compensation committee of any other company that has an executive officer serving as a member of our Board. None of our executive officers serves as a member of the board of directors of any other company that has an executive officer serving as a member of our Compensation Committee. None of our directors or executive officers are members of the same family.

CODE OF ETHICS

Our Board of Directors adopted a code of ethics that applies to our Chief Executive Officer, Executive Vice President, who serves as our principal financial officer, Chief Financial Officer, Chief Accounting Officer and Treasurer, and a code of business conduct and ethics that applies to all our officers, directors and employees. Each is available on the Corporate Governance page in the Investor Relations section of our Web site (www.oceaneering.com). Any shareholder may obtain a printed copy of these codes from us upon request. Any change in or waiver of these codes of ethics will be disclosed on our Web site.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who own more than 10% of our Common Stock to file with the SEC and the NYSE initial reports of ownership and reports of changes in ownership of Common Stock. Based solely on a review of the copies of such reports furnished to us and representations that no other reports were required, we believe that all our directors and executive officers complied on a timely basis with all applicable filing requirements under Section 16(a) of the Exchange Act during 2012.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee of Oceaneering International, Inc.’s Board of Directors is comprised of the four directors named below. Each member of the Audit Committee is an independent director as defined by applicable Securities and Exchange Commission rules and New York Stock Exchange listing standards. The Committee met 11 times during the year ended December 31, 2012. The Committee reviewed and discussed with management and Ernst & Young LLP, Oceaneering’s independent registered public accounting firm, the interim financial information included in Oceaneering’s quarterly reports on Form 10-Q for the periods ended March 31, 2012, June 30, 2012 and September 30, 2012, prior to their being filed with the Securities and Exchange Commission. In addition, the Committee reviewed and discussed with management and Ernst & Young all of Oceaneering’s earnings releases in 2012 prior to the public release of those earnings releases.

The Committee reviewed and discussed with management and Ernst & Young Oceaneering’s consolidated financial statements for the year ended December 31, 2012. Members of management represented to the Committee that Oceaneering’s consolidated financial statements were prepared in accordance with generally accepted accounting principles. The Committee discussed with Ernst & Young matters required to be discussed under the standards of the Public Company Accounting Oversight Board. The Committee also reviewed and discussed with management and Ernst & Young management’s report and Ernst & Young’s report on internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act.

Ernst & Young provided to the Committee the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding Ernst & Young’s independence, and the Committee discussed with Ernst & Young their independence from Oceaneering. The Committee concluded that Ernst & Young’s provision of non-audit services to Oceaneering and its affiliates is compatible with Ernst & Young’s independence.

Based on the Committee’s discussions with management and the independent auditors and the Committee’s review of the items referred to above, the Committee recommended to Oceaneering’s Board of Directors that Oceaneering’s audited consolidated financial statements as of and for the year ended December 31, 2012 be included in the Form 10-K for the year ended December 31, 2012 filed with the SEC.

PROPOSAL 2

ADVISORY VOTE ON A RESOLUTION TO APPROVE

THE COMPENSATION OF OCEANEERING’S NAMED EXECUTIVE OFFICERS

As required by Section 14A(a)(1) of the Exchange Act, we are providing our shareholders the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement.

In making compensation decisions, the Compensation Committee of our Board of Directors considers all elements of compensation when setting each element of compensation. The Compensation Committee assesses each element of base salary, annual incentive bonus, long-term incentive compensation and retirement plan values against a combination of available information from the most recent proxy statements of a peer group of publicly traded companies and survey data from the energy and general industries.

As described in detail under the “Compensation Discussion and Analysis,” section of this Proxy Statement below, our compensation program for Named Executive Officers is designed to attract, retain and motivate key executives and to deliver a competitive package that is aligned with our shareholders’ interests, while at the same time avoiding the encouragement of unnecessary or excessive risk taking.

A significant portion of our compensation program is delivered through variable compensation elements that are tied to key performance objectives of the Company. Approximately half of the total direct compensation (annual salary, annual incentives and long-term incentives) of our Named Executive Officers is performance-based. More than half of the estimated grant date value of their long-term incentive awards is performance-based.

Our 2012 financial results and achievement of specific financial goals for the period of 2010 – 2012 resulted in annual incentives and long-term incentive performance unit cash payouts for 2012 in excess of target levels. We reported record earnings for 2012 and record earnings for eight of the last nine years. In addition to our record earnings in 2012, other highlights for the year include:

• our attainment of higher operating income in 2012 than in 2011 in all five of our operating business segments;

• our 20% increase in regular quarterly dividends to $0.18 per common share, to return a greater portion of our earnings to our shareholders;

• our repurchase of 400,000 shares of our Common Stock under a stock repurchase plan we adopted in 2010;

• our substantial investment in opportunities to expand our business, with 2012 capital expenditures of approximately $310 million (including acquisitions), of which $198 million were spent on expanding and upgrading our remotely operated vehicle fleet;

• our commencement of a three-year field support vessel services contract offshore of Angola;

• the increase in our subsea products backlog at year-end to $681 million, an increase of 78% since the end of 2011, including the largest umbilical order in our history; and

• our ending the year with a balance sheet that remains conservatively capitalized, with approximately $121 million of cash, $94 million of debt and $1.8 billion of equity.

13

The vote on this resolution is not intended to address any specific element of compensation; rather the vote relates to the compensation of Named Executive Officers as described in this Proxy Statement in accordance with the rules of the SEC. As an advisory vote, it is not binding. However, our Board of Directors and our Compensation Committee, which is responsible for designing and overseeing the administration of our executive compensation program, will consider the outcome of the vote when making future compensation decisions for our Named Executive Officers.

Accordingly, we ask our shareholders to vote on the following resolution:

RESOLVED, that Oceaneering’s shareholders approve, on an advisory basis, the compensation of the Named Executive Officers, as disclosed in Oceaneering’s Proxy Statement for its 2013 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the 2012 Summary Compensation Table and the other compensation-related tables and accompanying narrative disclosures.

Vote Required and Board Recommendation

Our Board of Directors unanimously recommends a vote FOR the approval of the compensation of our Named Executive Officers as disclosed in this Proxy Statement. The persons named in the accompanying proxy intend to vote such proxy FOR approval of the compensation of our Named Executive Officers unless a choice is set forth therein or unless an abstention or broker “non-vote” is indicated therein.

In accordance with our bylaws, the adoption of this proposal requires the affirmative vote of a majority of the shares of Common Stock present in person or by proxy and entitled to vote on the proposal at the 2013 Annual Meeting of Shareholders. Because abstentions are counted as present for purposes of the vote on this proposal, but are not votes “FOR” this proposal, they have the same effect as votes “AGAINST” this proposal. Broker non-votes will have no effect on this vote.

14

COMPENSATION DISCUSSION AND ANALYSIS

The following discussion and analysis contains statements regarding future individual and company performance goals and measures. These goals and measures are disclosed in the limited context of Oceaneering’s compensation programs and should not be understood to be statements of management’s expectations or estimates of results or other guidance. Oceaneering cautions investors not to apply these statements to other contexts.

The following Compensation Discussion and Analysis, or “CD&A,” provides information regarding the compensation programs in place for our current Chief Executive Officer, our Executive Vice President, who serves as our principal financial officer, and our three other most highly compensated executive officers during 2012. We refer to these five individuals in this Proxy Statement as the “Named Executive Officers.” This CD&A includes information regarding, among other things, the objectives of our compensation program, the achievements that the compensation program is designed to reward, the elements of the compensation program (including the reasons why we employ each element and how we determine amounts paid) and how each element fits into our overall compensation objectives.

Executive Summary

Our executive compensation program is designed to attract, retain and motivate key executives and to deliver a competitive package to our Named Executive Officers that is aligned with our shareholders’ interests, as demonstrated by the following:

• The primary components of our compensation program consist of annual base salary, annual incentives, long-term incentives and retirement plans which are designed in the aggregate to provide opportunity which is competitive with the 50th percentile of a peer group and survey data identified by a compensation consultant retained by the Compensation Committee of our Board of Directors (the “Committee”);

• A significant portion of the program is delivered through variable compensation elements that are tied to key performance objectives of Oceaneering. Approximately half of the total direct compensation (annual salary, annual incentives and long-term incentives) is performance-based. More than half of the estimated grant date value of long-term incentive awards is performance-based; and

• Our 2012 financial results and the achievement of specific financial goals for the period of 2010 – 2012 resulted in annual incentive and long-term incentive performance unit payouts exceeding target levels. We reported record earnings for 2012 and for eight of the last nine years.

In 2012, the compensation consultant retained by the Committee performed an assessment of:

• The competitiveness of cash compensation, equity awards and retirement benefits provided to our Named Executive Officers relative to our peer group and the compensation consultant’s survey data; and

• Oceaneering’s performance in 2011 and 2009 – 2011 relative to our peer group with regard to the following financial metrics:

—  revenue growth;

— net income growth;

— earnings-per-share growth;

— cash flow margin;

— return on invested capital; and

— total shareholder return.

The compensation consultant assessed that the total annual value of the above-described primary components of our compensation program for our Named Executive Officers in the aggregate was positioned at the median of the peer group data used by the compensation consultant. The compensation consultant compared Oceaneering’s one- and three-year financial performance as compared to the peer group for the above metrics. The compensation consultant assessed that the average of Oceaneering’s performance across all the above metrics for one- and three-year periods ended December 31, 2011 was above the median at the 71st and 77th percentiles, respectively, of the peer group and, when measuring one- and three-year total shareholder return, was above the median at the 94th and 82nd percentiles, respectively, of the peer group.

15

Compensation Philosophy and Objectives

Our executive compensation program is designed to attract and retain key executives, motivate them to achieve our short-term and long-term objectives without subjecting us to excessive and unnecessary risks, and reward them for superior performance. We use several different compensation elements in the executive compensation program which are geared to both our short-term and long-term performance. The following principles influence the design and administration of our executive compensation program.

Compensation Should Be Related to Performance

The Committee and our Board of Directors believe that a significant portion of a Named Executive Officer’s direct compensation should be tied to overall company performance and measured against financial goals and objectives.

Under the performance-based portions of our compensation arrangements, our basic philosophy is that, in years when performance is better than the objectives established for the relevant performance period, Named Executive Officers should be paid more than the target awards and, when our performance does not meet planned objectives, incentive award payments should be less than such targets, in the absence of unusual circumstances.

Compensation Programs Should Motivate Executives to Remain With Us

We believe that there is significant value to our shareholders for Named Executive Officers to remain with our company over time. Our business is built significantly by executives who can develop and maintain customer relationships over time. Also, value is built by executives who understand the unique business and technical aspects of our industry. For these reasons, a significant element of our historical executive compensation arrangements has been long-term incentive compensation arrangements, with awards that have provided for vesting over several years. In addition, we provide our executive officers with some financial security in the event of a change of control, to promote long-term retention. We also provide for long-term benefits through retirement plans (see “– Post-Employment Compensation Programs” below).

Incentive Compensation Should Represent a Significant Part of an Executive’s Total Direct Compensation

We believe that the portion of a Named Executive Officer’s total compensation that varies with our overall performance objectives should increase as the scope and level of the individual’s business responsibilities and role in the organization increase. We believe that approximately one-half of the total direct compensation (the sum of annual base salary, annual incentive bonus and long-term incentive compensation) of the Named Executive Officers should be at risk against short- and long-term performance goals, and our Chief Executive Officer should be subject to a greater amount of such risk than other Named Executive Officers.

Incentive Compensation Should Balance Short-Term and Long-Term Performance

We strive to maintain an executive compensation program that balances short-term, or annual, results and long-term success. To reinforce the importance of this balancing, we regularly provide the Named Executive Officers both annual and long-term incentives. We believe we should avoid disproportionately large short-term or annual incentives that could encourage the Named Executive Officers to take excessive and unnecessary risks. The value for participants in our long-term incentive plans generally increases at higher levels of responsibility, as executives in these leadership roles have the greatest influence on our strategic direction and results over time.

The Committee’s approach to long-term incentives is to make awards of service-based restricted stock units and performance units to our executive officers and other key employees. Assuming restricted stock value based on grant date value established by the Financial Accounting Standards Board’s Accounting Standards Codification Topic 718 – Stock Compensation (“FASB ASC Topic 718”) and performance units notionally valued at $100 per unit for achievement of performance goals at target level, the Committee believes that the performance units should account for more than one-half of the total annual long-term incentive compensation of the Named Executive Officers and the service-based restricted stock units should account for the balance. The Committee believes that this approach promotes our philosophy of rewarding executives for growing shareholder value over time. Upon vesting, settlement of the restricted stock units will be made in shares of our common stock, with some shares withheld to satisfy withholding tax requirements. Upon vesting, the value of the performance units will be paid in cash.

16

Compensation Levels Should Be Competitive

The Committee reviews competitive compensation information as part of its process in establishing total direct compensation and retirement plan values that are competitive. In making compensation decisions, the Committee considers all elements of compensation when setting each element of compensation. The Committee assesses each element of base salary, annual incentive bonus, long-term incentive compensation and retirement plan values against a combination of available information from the most recent proxy statements of a peer group of publicly traded companies and survey data from the energy and general industries.

The Role of the Compensation Committee

The Committee has the primary authority to establish compensation for the Named Executive Officers and other key employees and administers all our executive compensation plans and agreements. The Committee annually reviews corporate goals and objectives, and sets the compensation levels for Named Executive Officers based on the Committee’s evaluation. Our Chief Executive Officer assists the Committee by providing annual recommendations regarding the compensation of the Named Executive Officers and other key employees, excluding himself. The Committee can exercise its discretion in modifying or accepting these recommendations. The Chief Executive Officer attends Committee meetings. However, the Committee also meets in executive session without the Chief Executive Officer or other members of management present.

The Committee reviews comparative compensation information compiled by a compensation consultant as described in “– The Role of the Compensation Consultant” below; however, the Committee does not base its decisions on targeting compensation to specific benchmarks. Comparative compensation is one factor used by the Committee in making its compensation decisions. Overall, however, our compensation program for Named Executive Officers is intended to create a total compensation opportunity that, on average, is competitive with the 50th percentile in the aggregate of appropriate competitive comparative compensation for a Named Executive Officer as discussed in “– The Role of the Compensation Consultant” below. For additional information regarding the role and responsibility of the Committee, see “Committees of the Board – The Compensation Committee” above.

Impact of 2012 Say-on-Pay Vote on Executive Compensation

In approving the 2013 compensation of the Named Executive Officers who are continuing as executive officers, the Committee reviewed the vote on the say-on-pay proposal at the 2012 Annual Meeting of Shareholders. Approximately 96% of the votes cast on the say-on-pay proposal at that meeting were voted in favor of the proposal. The Committee believes this affirms shareholders’ support of Oceaneering’s approach to executive compensation. Accordingly, the Committee did not adopt any specific changes based on the vote. The Committee will continue to consider the outcome of Oceaneering’s say-on-pay votes when making future compensation decisions for Named Executive Officers. The Committee expects to continue to hold the advisory vote to approve named executive officer compensation every year.

The Role of the Compensation Consultant

In 2012, the Committee retained Mercer (the “Compensation Consultant”) to: (1) review the peer group of companies used for comparison purposes in 2011 and assess its continued validity; (2) conduct a review of our total direct compensation and value provided under the retirement plan programs for the Named Executive Officers and other key employees relative to proxy statement data of the peer group of companies and survey data; (3) conduct a pay-for-performance analysis to assess the alignment of executive pay and company performance for Oceaneering and the peer group of companies identified; (4) assess Oceaneering’s compensation for nonemployee directors relative to compensation programs of a peer group of companies; and (5) assist in assessment of potential excise taxes pursuant to Section 4999 of the Internal Revenue Code assuming a change of control occurred on December 31, 2012. The Committee has engaged the Compensation Consultant to assist the Committee since 2004. In 2012, the Committee made the decision to continue the engagement of the Compensation Consultant and approved the compensation and other terms of engagement for the Compensation Consultant, in each case without reliance on any recommendation from management. The Compensation Consultant’s only work for Oceaneering in 2012 was at the direction of the Committee, except for non-executive compensation advice provided in 2012, for which the Compensation Consultant and its affiliated companies were paid approximately $18,000. The Committee considered this and other factors in its recent assessment of the independence of the Compensation Consultant, in light of new rules of the SEC and new NYSE listing standards, and concluded that the Compensation Consultant’s work for the Committee does not raise any conflict of interest.

17

The Compensation Consultant assessed the continuing validity of the peer group of companies used for comparison purposes in the review it conducted for the Committee in 2011 and recommended a list of 17 publicly traded companies as the peer group for comparison purposes in 2012 (collectively, the “Compensation Peer Group”). The Compensation Peer Group is comprised of the same companies identified as the peer group in 2011, except that Pride International, Inc. (which was acquired by ENSCO plc) and Global Industries, Ltd. (which was acquired by Technip S.A.) were removed.

The companies included in the Compensation Peer Group were approved for inclusion by the Committee, primarily due to their operational focus broadly within the oilfield services industry and the belief that we compete with these companies for talent and for stockholder investment. The companies comprising the Compensation Peer Group were:

Bristow Group Inc.	Helix Energy Solutions Group, Inc.	Rowan Companies, Inc.
Cameron International Corporation	Key Energy Services, Inc.	Superior Energy Services, Inc.
Diamond Offshore Drilling, Inc.	McDermott International, Inc.	Tidewater Inc.
ENSCO plc	National Oilwell Varco, Inc.	Transocean Ltd.
Exterran Holdings, Inc.	Noble Corporation	Weatherford International Ltd.
FMC Technologies, Inc.	Oil States International, Inc.

The sources of the survey data used by the Compensation Consultant were (1) the 2012 U.S. Global Premium Executive Remuneration Suite, which combines all of the Compensation Consultant’s executive compensation survey data for a variety of executive-level positions in which approximately 2,630 organizations participated; (2) Mercer’s 2012 Total Compensation Survey for the Energy Sector, which reports pay for all segments of the energy business for a variety of executive level positions in which approximately 300 organizations participated; and (3) a 2012 Survey Report on Top Management Compensation prepared by Towers Watson & Co., which features data across multiple industries and geographies for a variety of executive positions in which approximately 435 organizations participated (collectively, the “Compensation Surveys”).

The Compensation Consultant identified the 25th, 50th and 75th percentiles for base salary, annual bonus incentive, long-term incentive compensation and retirement plan value, individually and in the aggregate for the comparable position of each of our Named Executive Officers from a blend of compensation information identified for the Compensation Peer Group from the most recent proxy statements filed with the SEC as of September 2012 by the companies comprising the Compensation Peer Group (weighted at 50%) and from the Compensation Surveys (weighted at 50% with each component weighted equally), except that the Compensation Peer Group information was used exclusively for evaluating retirement plan value, as retirement plan value information was not available in the Compensation Surveys. The Compensation Consultant presented this and other information to the Committee at the Committee’s regularly scheduled meeting in October 2012. The Compensation Consultant made a similar presentation to the Committee in October 2011.

2012 Executive Compensation Components

For 2012, the primary components of our compensation program for Named Executive Officers were:

• annual base salary;

• annual incentive awards paid in cash;

• long-term incentive programs comprised of restricted stock units and performance units; and

• retirement plans.

18

Pay-for-Performance

The Compensation Consultant assessed that the total direct compensation (the sum of annual base salary, annual incentive awards and long-term incentive programs) and total compensation annual value (the sum of total direct compensation and retirement plans value) for our Named Executive Officers were each positioned in the aggregate at the median of the relevant market data. This assessment was based on the Compensation Surveys and Compensation Peer Group disclosure data (for total direct compensation), and Compensation Peer Group disclosure data (for total annual compensation value), discussed in “ – The Role of the “Compensation Consultant” above.

The Compensation Consultant assessed Oceaneering’s performance in 2011 and 2009 – 2011 relative to the Compensation Peer Group with regard to the following metrics:

• revenue growth;

• net income growth;

• earnings-per-share growth;

• cash flow margin;

• return on invested capital; and

• total shareholder return.

The Compensation Consultant compared Oceaneering’s one- and three-year financial performance as compared to the Compensation Peer Group for the above metrics. The Compensation Consultant assessed that the average of Oceaneering’s performance across all the above metrics for one- and three-year periods ended December 31, 2011 was above the median at the 71st and 77th percentiles, respectively, of the Compensation Peer Group and, when measuring one- and three-year total shareholders return, was above the median at the 94th and 82nd percentiles, respectively, of the Compensation Peer Group.

Annual Base Salary

The Committee generally considers base salary levels annually, as well as upon a promotion or significant change in job responsibility. Each year, our Chief Executive Officer recommends base salaries for the other Named Executive Officers based on historical levels of base salaries and general market movement, with adjustments he subjectively deems appropriate based on the overall performance of the Named Executive Officer, including a review of contributions and performance, over the past year. In reviewing the Chief Executive Officer’s recommendations and in deciding base salaries for all Named Executive Officers, the Committee considers each officer’s level of responsibility, experience, tenure, performance and the comparative compensation information provided by the Compensation Consultant. The Committee’s evaluation of each Named Executive Officer also takes into account an evaluation of Oceaneering’s overall performance. In February 2012, the Committee approved salary increases which took effect as of January 1, 2012 of 8.3% for Mr. McEvoy and ranging from 3.2% to 13.2% for the other Named Executive Officers.

Annual Incentive Awards Paid in Cash

In late February or early March of each year, the Committee approves a performance-based annual cash bonus award program under a shareholder-approved Incentive Plan for our executive officers. The cash bonus award opportunities under that program for our Named Executive Officers have generally been based on a comparison of our net income for the year to target net income for that year. For participating employees other than executive officers, the cash bonuses have generally been based upon the level of achievement of a combination of our net income, financial and non-financial goals of our applicable profit center for that employee, and individual goals. For each participant, the maximum award achievable is an approved percentage of the participant’s annual salary as of a specified date earlier than the approval date of the program. In late February or early March of each year, the Committee also approves the final bonus amounts under the cash bonus award program for the previous year.

In February 2012, the Committee approved a cash bonus award program for 2012. Under this program, bonuses were determined by a comparison of our net income in calendar year 2012 to target net income for that year. The maximum cash pay-out under the program for each Named Executive Officer was a specified percentage of that executive’s base salary effective as of January 31, 2012. For the Named Executive Officers, the percentage of net income that Oceaneering had to achieve for any bonus to be payable to a Named Executive Officer was 80% of target net income for the 2012 program. As recommended by our Chief Executive Officer and approved by the Committee, the target amount for our net income in 2012 was $286.3 million, an amount that was 21% more than the net income we achieved in 2011 and that equated to slightly above the high end of our published earnings per share guidance range for 2012. The Named Executive Officers in the program for 2012 and their respective maximum payouts as a percentage of base salary were: Mr. McEvoy – 150%; Mr. Migura – 125%; Mr. Kerins – 80%; Mr. Eriksen – 80%; and Mr. Hewlett – 70%. In 2012, approximately one-third of the targeted annual and long-term performance-based incentive compensation of the Named Executive Officers was attributable to annual incentive performance goals.

The following table notes the percentage of maximum payout to a Named Executive Officer under the program for the percentage of target net income achieved. The Committee had the discretion to award an amount less than that calculated.

In February 2013, the Committee approved annual incentive awards for 2012. Oceaneering achieved net income for 2012 which was slightly more than the target performance goal for 2012 and the Committee awarded amounts to the Named Executive Officers under the 2012 Cash Bonus Award Program which are reflected in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” below. The Committee also awarded additional merit bonuses to Messrs. McEvoy, Migura, Eriksen and Hewlett which are reflected in the “Bonus” column of the “Summary Compensation Table” below, in recognition of their leadership which contributed to our achieving a record level of net income for 2012.

Long-Term Incentive Compensation

Prior to 2006, we granted stock options annually and restricted stock or stock unit awards every three years to our executive officers and other key employees. However, in 2006 the Committee decided to refrain from using stock options as an employee compensation element for our executive officers and other employees for the foreseeable future and to instead use annual grants of service-based restricted stock unit awards and performance unit awards. Accordingly, no stock options were awarded in 2012. In April 2009, the Committee adopted a policy that Oceaneering will not provide U.S. federal income tax gross-up payments to any of its directors or executive officers in connection with future awards of restricted stock or stock units (although, as discussed below under “ – Change-of-Control Agreements,” the Level I Change-of-Control Agreements we have with two of our Named Executive Officers since 2001 provide for tax gross-ups for federal excise taxes on so-called “parachute payments,” which could apply to such future awards). This policy formalized our approach to U.S. federal income tax gross-up payments with respect to such awards since 2004. There are no outstanding incentive awards that provide for tax gross-up payments.

In deciding upon a methodology for determining the elements of our long-term incentive program, the Committee established the following objectives:

• deliver competitive economic value;

• reduce annual share utilization;

• preserve the alignment of the executive’s financial and shareholding interest with those of our shareholders, generally;

• attract and retain executives and other key employees;

• focus management attention on specific performance measures that have a strong correlation with the creation of shareholder value; and

• provide that approximately one-half of an executive’s total direct compensation is performance-based.

In order to achieve these objectives in 2012, the Committee decided to continue to utilize our long-term incentive program, which delivers value through two vehicles: restricted stock unit awards; and performance unit awards. The Committee expects to continue its practice of considering these long-term incentive awards in late February or early March of each year. Long-term incentive awards to new employees or in connection with other events such as promotions are considered at the next scheduled Committee meeting after the hire date or after the event occasioning the consideration of the award.

In February 2012, performance unit and service-based restricted stock unit awards were granted to the Named Executive Officers. At the notional value of $100 per performance unit for achievement of performance goals at target level, the performance unit and restricted stock unit awards comprised an estimated 52% and 48%, respectively, of the estimated grant date total long-term incentive value of these awards to the Named Executive Officers. The restricted stock units are scheduled to vest in full on the third anniversary of the award date, subject to earlier vesting if the employee meets specified age or age and years of service requirements or in the event of the termination or constructive termination of an employee’s employment in connection with a change of control of Oceaneering or due to death or disability. One-third of the awards to Messrs. McEvoy and Migura vested in December 2012, as a result of each of them having met the applicable age and years of service requirements. Each restricted stock unit represents the equivalent of one share of our common stock but carries no voting or dividend rights. Settlement of vested restricted stock units will be made in shares of our common stock, with some shares withheld to satisfy withholding tax requirements. The aggregate grant date fair value of restricted stock units awarded to Named Executive Officers is reflected in the “Stock Awards” column of the “Summary Compensation Table” and “Grant Date Fair Value of Stock and Stock Option Awards” column of the “Grants of Plan-Based Awards” table below.

21

The performance units awarded in February 2012 are scheduled to vest in full on the third anniversary of the award date, subject to similar early vesting terms as are applicable to the restricted stock units. The Committee approved specific financial goals and measures based on cumulative cash flow (as defined) and a comparison of return on invested capital and cost of capital for the three-year period of January 1, 2012 through December 31, 2014 to be used as the basis for the final value of the performance units. Those measures were selected because of the Committee’s belief that they have a strong correlation with the creation of shareholder value. The amount of cumulative cash flow during this three-year performance period necessary to achieve the target level goal for this measure is $1.80 billion. This amount was selected because it was three times the annual cash flow then expected to be achieved in 2012. The amounts to be achieved by Oceaneering to reach the threshold and maximum are $200 million less and $200 million more, respectively, than the target level amount. Oceaneering’s return on invested capital must exceed its estimated cost of capital over this three-year performance period by 25% for the target level goal to be achieved for this performance measure. For the threshold level to be achieved, the return on invested capital must equal our estimated cost of capital, and for the maximum level to be achieved the return on invested capital it must be 50% in excess of our estimated cost of capital. The final value of each performance unit may range from $0 to $150, with the threshold, target and maximum levels of achievement of goals valued at $75, $100 and $150, respectively. If the calculated unit value exceeds $100, the Committee retains discretion to reduce such value to any amount above or equal to $100. The value of vested performance units will be payable in cash.

The determination of the final value of each performance unit is based on the application of the following grid (with interpolation between the specified levels):

Cumulative Three – Year Cash Flow	Unit Values
Maximum		$75.00	$112.50	$125.00	$150.00
Target		$50.00	$  87.50	$100.00	$125.00
Threshold		$37.50	$  75.00	$  87.50	$112.50
Below Threshold		$  0.00	$  37.50	$  50.00	$  75.00
		Below Threshold	Threshold	Target	Maximum
		Return on Invested Capital/Cost of Capital

The estimated future payout of the performance unit awards to Named Executive Officers if each of the performance measures is achieved at the threshold, target or maximum level is reflected in the “Estimated Future Payouts Under Non-Equity Incentive Plan Awards” column of the “Grants of Plan-Based Awards” table below.

For 2012, approximately 54% of the targeted total direct compensation of Mr. McEvoy, our Chief Executive Officer, was at risk against short- and long-term performance goals and between approximately 49% and 53% was at risk for each of the other Named Executive Officers.

Post-Employment Compensation Programs

Retirement Plans

We maintain a 401(k) plan and a Supplemental Executive Retirement Plan (“SERP”). All of our employees who meet the eligibility requirements may participate in our 401(k) plan. Each of the Named Executive Officers participated in our 401(k) plan in 2012. Participation in our SERP includes Named Executive Officers and other key employees selected for participation by the Committee. Our SERP was established to provide a benefit to our executives and other key employees in excess of Internal Revenue Code limits for our 401(k) plan, in order to attract and motivate participants to remain with us and provide retirement plan values that are competitive with those provided by companies within the Compensation Peer Group. Under our SERP, we credit each participant’s notional account with a percentage determined by the Committee of the participant’s base salary, subject to vesting. A participant may elect to defer a portion of base salary and annual bonus for accrual pursuant to our SERP. Amounts accrued under our SERP are adjusted for earnings and losses as if they were invested in one or more investment vehicles selected by the participant from those designated as alternatives by the Committee. A participant’s vested interest in the plan is generally distributable upon termination. The percentages of base salary credited for Named Executive Officers in 2012 were: Mr. McEvoy – 50%; Mr. Migura – 40%; Mr. Kerins – 25%; Mr. Eriksen – 20%; and Mr. Hewlett – 20%. These amounts reflected no change in the percentage of base salary credited from 2011, except Mr. Eriksen’s participation level was increased from 10% to 20% effective January 2012. Please see the “Non-Qualified Deferred Compensation” table and accompanying narrative for further information about our SERP and contributions to the Named Executive Officers’ accounts.

Change-of-Control Agreements

In 2001, we entered into change-of-control agreements (each, a “Level I Change-of-Control Agreement”) with Messrs. McEvoy and Migura, each of whom at the time was a Named Executive Officer, replacing each of their respective prior senior executive severance agreements. In December 2008, we amended these Change-of-Control Agreements to clarify certain provisions and provide for compliance with Section 409A of the Internal Revenue Code. In May 2011, we entered into change-of-control agreements (each, a “Level II Change-of-Control Agreement”) with Messrs. Kerins, Eriksen and Hewlett. The Level I and II Change-of-Control Agreements are collectively called “Change-of-Control Agreements.” The payment and benefits under our Change-of-Control Agreements did not influence and were not influenced by the other elements of compensation, as the change-of-control payments and benefits serve different objectives and due to the fact that a change of control or other triggering event may never occur. We generally limit eligibility for change-of-control agreement participation to executive officers whose full support and sustained contribution would be important to the successful completion of a change of control. We believe the benefits provided by the Change-of-Control Agreements help promote long-term retention by providing some financial security to these Named Executive Officers against the risk of loss of employment which could result following a change of control of our company. The Change-of-Control Agreements entitle the individual to receive a severance package, described below, in the event of the occurrence of both a change of control and a termination of the executive’s employment by us without cause (as defined below) or by the executive for good reason (as defined below) during a period of time beginning a year prior to the occurrence or, in some cases, the contemplation by the Board of a change in control (the “Effective Date”) and ending two years following the Effective Date. For purposes of the Change-of-Control Agreements, a change of control is defined as occurring if:

• any person is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of our securities representing 20% or more of the combined voting power of our outstanding voting securities, other than through the purchase of voting securities directly from a private placement by us;

• the current members of our Board, or subsequent members approved by at least two-thirds of the current members, no longer comprise a majority of our Board;

• our company is merged or consolidated with another corporation or entity, and our shareholders own less than 60% of the outstanding voting securities of the surviving or resulting corporation or entity;

• there has been a consummation of either a tender offer or exchange offer by a person other than us for the ownership of 20% or more of our voting securities; or

• there has been a disposition of all or substantially all of our assets.

23

As defined in each Change-of-Control Agreement, cause for termination by Oceaneering means conviction by a court of competent jurisdiction, from which conviction no further appeal can be taken, of a felony-grade crime involving moral turpitude related to service with us.

As defined in each Change-of-Control Agreement, good reason for termination by the executive includes:

• any adverse change in status, title, duties or responsibilities;

• any reduction in annual base salary, SERP contribution level by us, annual bonus opportunity or aggregate long-term compensation, all as may be increased subsequent to date of the Change-of-Control Agreement;

• any relocation;

• the failure of a successor to assume the Change-of-Control Agreement;

• any prohibition by us against the individual engaging in outside activities permitted by the Change-of-Control Agreement;

• any purported termination by us that does not comply with the terms of the Change-of-Control Agreement; or

• any default by us in the performance of our obligations under the Change-of-Control Agreement.

Severance Package for Level I Change-of-Control Agreements

The severance package provided for an executive’s Level I Change-of-Control Agreement consists of an amount equal to three times the sum of:

• the executive’s highest annual rate of base salary during the then-current year or any of the three years preceding the year of termination;

• an amount equal to the maximum award the executive is eligible to receive under the then-current annual bonus plan; and

• an amount equal to the maximum percentage of the executive’s annual base salary contributed by us for him in our SERP for the then-current year multiplied by the executive’s highest annual rate of base salary.

A minimum aggregate amount payable for these items is stated in each such executive’s agreement, which amount was calculated using the year-end December 31, 2001 amounts for each component.

The severance provisions also provide that, for each applicable individual:

• the benefits under all compensation plans, including restricted stock agreements, restricted stock unit agreements and performance unit agreements, would be paid as if all contingencies for payment and maximum levels of performance had been met; and

• the applicable individual would receive benefits under all other plans he then participates in for three years.

The Level I Change-of-Control Agreements provide that, if any payments made thereunder would cause the recipient to be liable for an excise tax because the payment is a “parachute payment” (as defined in the Internal Revenue Code), then we will pay the individual an additional amount to make the individual whole for that tax liability.

24

Severance Package for Level II Change-of-Control Agreements

The severance packages provided for an executive’s Level II Change-of-Control Agreement consists of an amount equal to two times the sum of:

• the executive’s highest annual rate of base salary during the then-current year or any of the three years preceding the year of termination; and

• an amount equal to the target award the executive is eligible to receive under the then-current annual bonus plan.

There is no minimum aggregate amount payable for these items.

The severance provisions also provide that, for each applicable individual:

• the benefits under all compensation plans, including restricted stock agreements, restricted stock unit agreements and performance unit agreements, would be paid as if all contingencies for payment and maximum levels of performance had been met; and

• the applicable individual would receive benefits under all other plans he then participates in for two years.

The Level II Change-of-Control Agreements do not provide for any payment to the executive for any excise tax the executive may be liable for if the payment is a “parachute payment.”

Perquisites

We provide our Named Executive Officers with perquisites and other benefits that we believe are reasonable and consistent with our overall compensation program to enable us to attract and retain employees for key positions. The Committee periodically reviews the levels of perquisites and other personal benefits provided to our executive officers. The perquisites provided to our Named Executive Officers in 2012 and our incremental cost to provide those perquisites are set forth in the “All Other Compensation” column of the “Summary Compensation Table” below and the related footnotes to that table.

Stock Ownership Guidelines

To align the interests of our directors, executive officers and shareholders, we believe our directors and executive officers should have a significant financial stake in Oceaneering. To further that goal, our Board adopted stock ownership guidelines in 2007, requiring that our nonemployee directors, Chief Executive Officer, Executive Vice President and Senior Vice Presidents maintain minimum ownership interests in Oceaneering. Our nonemployee directors are generally expected to own not less than a fixed number of shares equal to five times the current annual cash retainer generally paid to nonemployee directors divided by the closing price of our stock on the date of adoption of the policy, as adjusted for any stock splits or stock dividends with respect to our stock subsequent to that date.

Our Chief Executive Officer, Executive Vice President and Senior Vice Presidents are generally expected to own not less than a fixed number of shares equal to a multiple of their current annual base salary divided by the closing price of our stock on the date of adoption of the policy, as adjusted for any stock split or stock dividends with respect to our stock subsequent to that date. The multiple of current annual base salary used to determine the fixed number of shares is as provided in the following table.

Level	Base Salary Multiple
Chief Executive Officer		5
Executive Vice President		3
Corporate Senior Vice Presidents		3
Other Senior Vice Presidents		2

25

The following forms of ownership are recognized in determining the number of shares of our stock owned by a nonemployee director or executive officer for purposes of satisfying the stock ownership guidelines:

• direct ownership of shares;

• indirect ownership of shares, including stock or stock equivalents held in our retirement plan; and

• vested and unvested shares of restricted stock or stock units held under our long-term incentive programs.

A nonemployee director or executive has three years from the later of the date of adoption of the policy or the initial date of election or appointment to comply with stock ownership guidelines. The time period for satisfying such ownership requirement by an executive may be extended at the discretion of our Chief Executive Officer for an additional period of up to two years. In the event that a nonemployee director or executive does not meet the stock ownership level within the specified time period, he or she will be prohibited from selling any stock acquired through vesting of restricted stock or restricted stock units or upon exercise of stock options, except to pay for applicable taxes or the exercise price, until he or she satisfies the requirements. Each of our current nonemployee directors and Named Executive Officers is covered by this policy and currently satisfies the stock ownership guidelines applicable to him, with the exception of Mr. Murphy, who was appointed by the Board in August 2012 and has three years to satisfy the guidelines.

Tax Deductibility of Pay

Section 162(m) of the Internal Revenue Code generally disallows a deduction to public companies to the extent of excess annual compensation over $1 million paid to certain executive officers, except for qualified performance-based compensation. Our 2012 annual cash bonus program and 2012 performance unit program are intended to qualify as performance-based compensation under Section 162(m). Our general policy, where consistent with business objectives, is to preserve the deductibility of compensation to executive officers. We may authorize forms of compensation that might not be deductible if we believe they are in the best interests of Oceaneering and its shareholders. Our 2012 service-based restricted stock unit awards are not considered performance-based under Section 162(m) and, accordingly, are subject to the $1 million limit on deductibility. All or a portion of the value, when vested, of these restricted stock unit awards may not be deductible.

Compliance with Internal Revenue Code Section 409A

Section 409A of the Internal Revenue Code can impose significant additional taxes on the recipient of “nonqualified deferred compensation” arrangements that do not meet specified requirements regarding both form and operation. Some of the arrangements between Oceaneering and its executive officers and other employees provide, or might be considered to provide, nonqualified deferred compensation. We generally seek to ensure that our compensation arrangements are either exempt from or comply with Section 409A.

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Proxy Statement with the management of Oceaneering International, Inc., and, based on such review and discussions, the Compensation Committee recommended to the Board of Directors of Oceaneering that the Compensation Discussion and Analysis be included in this Proxy Statement.

(1) These columns show the potential value of the payout for each Named Executive Officer under the performance units awarded in 2012 if the threshold, target or maximum goal is satisfied for each of the performance measures. The potential payouts are performance-driven and, therefore, at risk. For a description of the awards, including business measurements for the three-year performance period and the performance goals for determining the payout, see “Compensation Discussion and Analysis – Long-Term Incentive Compensation” above.

(2) The amounts reflect the number of restricted stock units awarded to the Named Executive Officers in 2012. For a description of the awards see “Compensation Discussion and Analysis – Long-Term Incentive Compensation” above.

(3) The amounts reflect the aggregate grant date fair value of restricted stock units computed under FASB ASC Topic 718 awarded to the Named Executive Officers in 2012.

We do not provide a Pension Benefits Table because we have no qualified pension plan or other plan that would be reportable under the SEC’s rules applicable to Pension Benefits Tables.

Nonqualified Deferred Compensation

Our SERP is an unfunded, defined contribution plan for selected executives and key employees of Oceaneering, including the Named Executive Officers. Pursuant to our SERP, U.S. participants, including the Named Executive Officers, may defer up to 85% of their base salaries and 90% of their annual cash bonus amounts. We credit a participant’s notional account with a determined percentage of the participant’s base salary, subject to vesting. Benefits under our SERP are based on the participant’s vested portion of his or her notional account balance at the time of termination of employment. A participant vests in our credited amounts at the rate of 33% each year, subject to accelerated vesting upon the soonest to occur of: (1) the date the participant has completed ten years of participation; (2) the date that the sum of the participant’s age and years of participation equals 65; (3) the date of termination of employment by reason of death or disability; and (4) the date of termination of employment within two years following a change of control. Messrs. McEvoy, Migura, Kerins and Hewlett are fully vested in their SERP accounts. All participants are fully vested in deferred base salary and bonus.

Potential Payments on Termination or Change of Control

As described in the “Compensation Discussion and Analysis” above, Messrs. McEvoy and Migura have Level I Change-of-Control Agreements entered into in 2001; Messrs. Kerins, Eriksen, and Hewlett have Level II Change-of-Control Agreements entered into in 2011. Upon a change of control of Oceaneering, each of them may be subject to certain excise taxes pursuant to Section 4999 of the Internal Revenue Code. Pursuant to their Level I Change-of-Control Agreements, we have agreed to reimburse Messrs. McEvoy and Migura for all such excise taxes that may be imposed and any income taxes and excise taxes that may become payable as a result of the reimbursement. We have not agreed to reimburse Messrs. Kerins, Eriksen or Hewlett for any such amounts. Based on the amounts shown in the “Change of Control with Termination” column in the following tables, none of the Named Executive Officers would be subject to an excise tax liability, except Mr. McEvoy. Mr. McEvoy would be subject to an excise tax liability, assuming a change of control occurred on December 31, 2012. However, whether an excise tax liability will arise in the future will depend on the facts and circumstances in existence at the time a change-of-control payment becomes payable. All of the outstanding long-term incentive agreements of the Named Executive Officers have provisions for settlement in the event of death, disability or a change of control.

Assuming a December 31, 2012 termination date and, where applicable, using the closing sale price of our Common Stock of $53.79 per share on December 31, 2012, the tables below show potential payments to each of the Named Executive Officers under the existing contracts, agreements, plans or arrangements, whether written or unwritten, in the event of a termination of such executive’s employment, including amounts payable pursuant to benefits or awards in which the Named Executive Officers are already vested. As used in the agreements referenced in the tables below, the term “Change of Control” has the same meaning as the Change-of-Control Agreements define that term. For a summary of that definition, see “Compensation Discussion and Analysis – Change-of-Control Agreements” above.

(1) Payment or benefit only if involuntary termination is the result of a reduction in force.

(2) Amount for each indicated Named Executive Officer reflects an amount equaling three times the sum of: (a) his highest annual rate of base salary for the prior three years; (b) the maximum award he is eligible to receive under the annual cash bonus program for the current year; and (c) maximum percentage of base salary contribution level by us for him in our SERP for the current year multiplied by his highest annual rate of base salary in effect during the current year or any of the prior three years that is payable pursuant to the executive’s Change-of-Control Agreement.

(3) This amount reflects a tax gross-up payment to Mr. McEvoy as a result of tax that would have been imposed under Section 4999 of the Internal Revenue Code and, based on a termination as of December 31, 2012 following a change of control. Under Mr. McEvoy’s Level I Change-of-Control Agreement, we would reimburse Mr. McEvoy for such excise taxes and any income and excise taxes that would be payable as a result of that reimbursement. The calculation of the excise tax gross-up was based on an excise tax rate of 20%, a federal income tax rate of 35%, a Medicare tax rate of 1.45%, and no state or local income tax because Mr. McEvoy is a resident of the State of Texas, which does not impose such taxes on individuals. The calculation also treated the entire amounts of the performance unit awards as “parachute payments.”

(4) Amount for each indicated Named Executive Officer reflects the estimated value of the benefit to the executive to receive the same level of medical, life insurance and disability benefits for a period of three years after termination that is payable pursuant to the executive’s Change-of-Control Agreement.

(5) Amount for each Named Executive Officer reflects the value of shares of Common Stock that would be delivered for each outstanding unvested restricted stock unit pursuant to the executive’s 2010, 2011 and 2012 Restricted Stock Unit Agreements. Messrs. McEvoy and Migura are fully vested under their 2010 Restricted Stock Unit Agreements.

(6) Amount for each Named Executive Officer reflects the value of shares of Common Stock that would be delivered for each outstanding unvested restricted stock unit pursuant to the executive’s 2010, 2011 and 2012 Restricted Stock Unit Agreements and Change-of-Control Agreement. Messrs. McEvoy and Migura are fully vested under their 2010 Restricted Stock Unit Agreements.

(7) Upon death or disability, the performance units awarded pursuant to the 2011 and 2012 Performance Unit Agreements would vest. The amounts payable, if any, for each indicated Named Executive Officer pursuant to the executive’s 2011 and 2012 Performance Unit Agreements will not be known until completion of the three-year performance periods of January 1, 2011 – December 31, 2013 and January 1, 2012 – December 31, 2014, respectively, at which time the performance will be measured. For information about the goals and measures and the amounts payable, see “Compensation Discussion and Analysis – Long-Term Incentive Compensation” above.

(8) Amount for each Named Executive Officer reflects cash payment for outstanding unvested performance units at the maximum goal level pursuant to the executive’s 2010, 2011 and 2012 Performance Unit Agreements ($150 per unit) and Change-of-Control Agreement.

(9) Amount for each indicated Named Executive Officer reflects the value of shares of Common Stock that would be delivered for each outstanding vested restricted stock unit pursuant to the executive’s 2010, 2011 and 2012 Restricted Stock Unit Agreements and Change-of-Control Agreement.

(10) Amount for each indicated Named Executive Officer reflects cash payment for vested performance units awarded pursuant to the executive’s 2010 Performance Unit Agreement as a result of our achievement in excess of the maximum goals for the performance measures of (i) comparison of return on invested capital and cost of capital and (ii) cumulative cash flow for the three-year performance period of January 1, 2010 – December 31, 2012, as certified by the Compensation Committee in February 2013. This amount is included for each indicated executive in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” above. The amount payable, if any, for each indicated Named Executive Officer pursuant to the executive’s 2011 and 2012 Performance Unit Agreements for outstanding vested performance units will not be known until completion of the three-year performance periods of January 1, 2011 – December 31, 2013 and January 1, 2012 – December 31, 2014, respectively, at which time the performance will be measured. For information about the goals and measures and the amounts payable, see “Compensation Discussion and Analysis – Long-Term Incentive Compensation” above.

(11) Amount for each indicated Named Executive Officer reflects cash payment for outstanding vested performance units at the maximum level pursuant to the executive’s 2010, 2011 and 2012 Performance Unit Agreements ($150 per unit) and Change-of-Control Agreement.

(12) Amount for each indicated Named Executive Officer reflects the accumulated account values (including gain and losses) of contributions by the Named Executive Officer and Oceaneering for vested amounts and by Oceaneering for unvested amounts. For more information on SERP amounts, see “Nonqualified Deferred Contributions” above.

36

(13) Amount for each indicated Named Executive Officer reflects an amount equaling two times the sum of: (a) his highest annual rate of base salary for the prior three years; and (b) the target award he is eligible to receive under the annual cash bonus program for the current year that is payable pursuant to the executive’s Change-of-Control Agreement.

(14) Amount for each indicated Named Executive officer reflects the estimated value of the benefit to the executive to receive the same level of medical, life insurance and disability benefits for a period of two years after termination that is payable pursuant to the executive’s Change-of-Control Agreement.

Amount for the indicated Named Executive Officer reflects cash payment for performance units awarded pursuant to the executive’s 2010 Performance Unit Agreement as a result of our achievement in excess of the maximum goals for the performance measures of (i) comparison of return on invested capital and cost of capital and (ii) cumulative cash flow for the three-year performance period of January 1, 2010 – December 31, 2012, as certified by the Compensation Committee in February 2013. This amount is included for the executive in the “Non-Equity Incentive Plan Compensation” column of the “Summary Compensation Table” above. The amounts payable, if any, for each indicated Named Executive Officer pursuant to the executive’s 2011 and 2012 Performance Unit Agreements will not be known until the completion of the three-year performance periods of January 1, 2011 – December 31, 2013, and January 1, 2012 – December 31, 2014, respectively, at which time the performance will be measured. For information about the goals and measures and the amounts payable, see “Compensation Discussion and Analysis – Long-Term Incentive Compensation” above.

DIRECTOR COMPENSATION

During 2012, we paid each of our nonemployee directors, on a quarterly basis, an annual retainer of $80,000 with additional annual retainers of $15,000 to the Chairman of the Audit Committee and $8,000 to each of the Chairmen of the Compensation Committee and the Nominating and Corporate Governance Committee. During 2012, we did not pay nonemployee directors any additional amount for attendance at meetings of the Board or a Committee of the Board. Mr. Huff, the Chairman of the Board, did not receive the above board fees in 2012 pursuant to the terms of his 2012 Chairman Restricted Stock Unit and Performance Unit Agreements. Mr. McEvoy, our Chief Executive Officer, does not receive separate compensation for his service as a director. See “Summary Compensation Table” above for information concerning the compensation paid to Mr. McEvoy.

During 2012, besides payment of annual retainers, our nonemployee directors were also allowed to participate in health care coverage the same as provided to employees in our basic medical plans. Nonemployee directors could elect to participate in the health care plan without payment of any monthly premium and participate in a supplemental medical plan at no cost to the director. We paid the Medicare premium for Mr. Hughes. Mr. Huff’s Amended Service Agreement, which is described below, provides for medical coverage on an after-tax basis to Mr. Huff, his spouse and children for their lives. All directors are provided a group personal excess liability insurance policy at no cost to the directors and they are reimbursed for their travel and other expenses involved in attendance at Board and committee meetings and activities.

In 2012, our nonemployee directors participated in our shareholder-approved 2010 Incentive Plan. Under this plan in 2012, Messrs. Collins, DesRoche, Hooker, Hughes and Pappas, were each awarded 8,000 shares of restricted stock, and Mr. Murphy, who was appointed by the Board in August 2012, was awarded 4,000 shares of restricted stock. The restricted stock awards are scheduled to vest in full on the first anniversary of the award date, subject to (1) earlier vesting on a change of control or the termination of the director’s service due to death and (2) such other terms as are set forth in the award agreement. Under this plan in 2012, Mr. Huff was awarded 20,000 restricted stock units and 15,000 performance units with the terms as set forth in his 2012 Chairman Restricted Stock Unit and Performance Unit Agreements. The restricted stock units and performance units awarded to Mr. Huff are scheduled to vest on a pro-rata basis within three years from the award date, with a final vesting date in February 2015, subject to (a) earlier vesting by reason of Mr. Huff’s cessation of service as Chairman for reasons other than his refusal to serve and (b) other terms set forth in the award agreements. The performance units awarded to Mr. Huff have the same performance goals and measures over the same time period and with the same range of values payable as the performance units granted to executive officers. As provided in Mr. Huff’s 2012 Chairman Restricted Stock Unit and Performance Unit Agreements, he was not eligible in 2012 for any retainers or meeting fees otherwise applicable to nonemployee directors. For more information on these restricted common stock unit and performance unit awards, see “Compensation Discussion and Analysis – Long-Term Incentive Compensation.” For information about stock ownership guidelines for nonemployee directors, see “Compensation Discussion and Analysis – Stock Ownership Guidelines.”

37

As we previously disclosed, we entered into a Restricted Stock Unit Agreement and a Performance Unit Agreement with Mr. Collins in 2011 when he was serving as our President and Chief Executive Officer. The restricted stock units and performance units awarded to Mr. Collins are scheduled to vest on a-pro-rata basis within three years from the award date, with a final vesting date in December 2013, subject to Mr. Collins’ serving as a director on a vesting date and earlier vesting by reason of (a) a change of control and (b) other terms set forth in the award agreements. The performance units awarded to Mr. Collins have the same performance goals and measures over the same time period and with the same range of values payable as the performance units then awarded to other executive officers at the time of the awards.

The table below summarizes the compensation of our nonemployee directors for the year ended December 31, 2012.

(1) Amounts shown are attributable entirely to annual retainers as described in “Director Compensation” above.

(2) The amounts reflect the aggregate grant date fair value of awards by us in 2012 related to restricted stock and restricted stock unit awards computed in accordance with FASB ASC Topic 718. For a discussion of valuation assumptions, see Note 8 to our consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2012. The aggregate number of restricted shares and/or units of stock outstanding as of December 31, 2012, for each of Messrs. DesRoche, Hooker, Hughes and Pappas was 8,000, for Mr. Murphy it was 4,000, for Mr. Collins it was 86,000 (including restricted shares and restricted stock units), and for Mr. Huff it was 70,000. There are no shares subject to outstanding stock options.

(3) The amount represents the cash payment for performance units for Mr. Huff pursuant to his 2010 Chairman Performance Unit Agreement and for Mr. Collins pursuant to his 2010 Performance Unit Agreement awarded when he was Chief Executive Officer, as a result of our achievement in excess of the maximum goals for each of the performance measures of (i) comparison of return on invested capital and cost of capital and (ii) cumulative cash flow, for the performance period of January 1, 2010 – December 31, 2012, as certified by our Board in February 2013.

(4) The amount shown for each attributable perquisite or benefit does not exceed the greater of $25,000 or 10% of the total amount of perquisite received by any director, except as quantified for Mr. Huff in footnote (5) below.

(5) The amounts shown for 2012 are attributable to the following:

• Mr. Huff: (i) $17,408 for tax gross-up payments associated with his medical coverage described below and (ii) perquisites and other personal benefits comprised of: provision of excess liability insurance; and annual premiums and reimbursement of medical costs for health care, including premium and costs reimbursed for a supplemental medical insurance plan ($69,802).

• Mr. Collins: (i) $720 for the additional amount of cash dividends on Common Stock initiated after the date of his restricted stock award described in footnote (2) above and (ii) perquisites and other personal benefits comprised of: excess liability insurance; personal use of company-owned fishing camp; and annual premium for basic health care provided by us; and premium and costs reimbursed for a supplemental medical insurance plan.

Service Agreement with Mr. Huff

As we previously disclosed, we entered into a Service Agreement with Mr. Huff in 2001 (the “Service Agreement”), when Mr. Huff was serving as our Chairman of the Board and Chief Executive Officer. The Service Agreement replaced Mr. Huff’s prior employment agreement. Since 2001, the Service Agreement provides (as did the prior employment agreement) medical coverage on an after-tax basis to Mr. Huff, his spouse and children during his employment with us and thereafter for their lives. The Service Agreement also continues to provide that if any payments thereunder would cause Mr. Huff to be liable for an excise tax because the payment is a “parachute payment” (as defined in the Internal Revenue Code), then we would pay Mr. Huff an additional amount to make him whole for that tax liability. The Service Agreement was amended in 2006 and 2008 (the “Amended Service Agreement”) to address, among other things, issues arising under Section 409A of the Internal Revenue Code. The Amended Service Agreement, among other things, provides for entitlement to post-retirement benefits of $800,000 per year for 10 years which vested and commenced on August 15, 2011, provided that in the event of Mr. Huff’s death, his disability or a change of control, all unpaid amounts would be accelerated and become payable in a non-discounted lump-sum payment. The Amended Service Agreement also provides for a tax-protection clause, generally to ensure that Mr. Huff would not be impacted adversely by taxes under Section 409A of the Internal Revenue Code.

Also as part of Mr. Huff’s retirement benefits, we established an irrevocable grantor trust, commonly known as a “rabbi trust,” to provide Mr. Huff greater assurance that we would set aside an adequate source of funds to fund the payment of the post-retirement benefits under the Amended Service Agreement, including the medical coverage benefits payable to Mr. Huff, his spouse and their children for their lives. In connection with establishment of the rabbi trust, we contributed to the trust a life insurance policy on the life of Mr. Huff which we had previously obtained, and we agreed to continue to pay the premiums due on that policy. When the life insurance policy matures, the proceeds of the policy will become assets of the trust. If the value of trust assets exceeds $4 million, as adjusted by the Consumer Price Index, at any time after January 1, 2012, the excess may be paid to us. However, because the trust is irrevocable, the assets of the trust are generally not otherwise available to fund our future operations until the trust terminates, which is not expected to occur during the lives of Mr. Huff, his spouse or his children. Furthermore, no tax deduction will be available for our contributions to the trust; however, we may benefit from future tax deductions for benefits actually paid from the trust (although benefit payments from the trust are not expected to occur in the near term, because we expect to make direct payments of those benefits for the foreseeable future).

Assuming a December 31, 2012 termination date of Mr. Huff’s serving as our Chairman of the Board (for reasons other than his refusal to serve as our Chairman of the Board) for any reason other than we have failed to fulfill our obligations under his Amended Service Agreement, and, where applicable using the closing sale price of our Common Stock of $53.79 per share on December 31, 2012, potential payments to Mr. Huff consist of: $6,400,000, which reflects the unpaid portion of Mr. Huff’s vested post-retirement benefit which would be accelerated and become payable in a non-discounted lump sum payment in the event of Mr. Huff’s death, his disability or a change of control; and $9,765,300, which reflects: (1) the value of shares of Common Stock that would be delivered for each outstanding vested and unvested restricted stock unit pursuant to the Amended Service Agreement and his Restricted Stock Unit

39

Agreements; and (2) a cash payment for outstanding performance units, pursuant to the Amended Service Agreement and under his Performance Unit Agreements, at the maximum goal level of $150 per unit. Based on these amounts, Mr. Huff would not be subject to an excise tax liability. However, whether an excise tax liability will arise in the future will depend on the facts and circumstances in existence at the time a change-of-control payment becomes payable.

Assuming a December 31, 2012 termination date of Mr. Huff’s serving as our Chairman of the Board as a result of his refusal to serve as our Chairman of the Board for any reason other than that we have failed to fulfill our obligations under the Amended Service Agreement, Mr. Huff would forfeit all unvested restricted stock units and performance units that were awarded to him and his vested performance units would be paid at the target goal level of $100 per unit, resulting in a reduction of $4,755,100 from the potential payment stated above pursuant to his applicable agreements.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Our Board of Directors adopted a written policy with respect to related-person transactions to document procedures pursuant to which such transactions are reviewed and approved or ratified. The policy applies to any transaction in which (1) Oceaneering or any of its subsidiaries is a participant; (2) any related person has a direct or indirect material interest; and (3) the amount involved exceeds $120,000, but excludes any transaction that does not require disclosure under Item 404(a) of Regulation S-K promulgated by the SEC. Under the policy, related persons include our directors, nominees to become a director, executive officers, beneficial owners of 5% or more of our voting securities, immediate family members of any of the foregoing persons, and any entity in which any of the foregoing persons is employed as an executive officer or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership. Our policy includes a process to monitor related-person transactions and, if a determination is made that a proposed transaction or category of transaction is a related person transaction, a submission is made to the Nominating and Corporate Governance Committee, which will consider all of the relevant facts and circumstances available and evaluate whether to approve or ratify the transaction.

Except as set forth in this Proxy Statement, no director or executive officer of Oceaneering or nominee for election as a director of Oceaneering, or holder of more than 5% of the outstanding shares of Common Stock, and no member of the immediate family of any such director, nominee, officer or security holder, to our knowledge, had any material interest in any transaction during the year ended December 31, 2012, or in any currently proposed transaction, to which Oceaneering or any subsidiary of Oceaneering was or is a party in which the amount involved exceeds $120,000.

No director or executive officer of Oceaneering who has served in such capacity since January 1, 2012 or any associate of any such director or officer, to the knowledge of the executive officers of Oceaneering, has any material interest in any matter proposed to be acted on at the 2013 Annual Meeting of Shareholders, other than as described in this Proxy Statement.

PROPOSAL 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

The Audit Committee of the Board of Directors has appointed Ernst & Young LLP, independent certified public accountants, as independent auditors of Oceaneering for the year ending December 31, 2013. Although we are not required to seek shareholder approval of the appointment, it has been our practice to do so. No determination has been made as to what action the Audit Committee would take if our shareholders fail to ratify the appointment. The Audit Committee retains the discretion to appoint a new independent registered public accounting firm at any time if the Audit Committee concludes such a change would be in the best interests of Oceaneering. Representatives of Ernst & Young LLP will be present at the meeting, will be given the opportunity to make a statement if they so desire and will be available to respond to appropriate questions of any shareholders.

In accordance with our bylaws, the approval of the proposal to ratify the appointment of Ernst & Young LLP as independent auditors of Oceaneering for the year ending December 31, 2013 requires the affirmative vote of a majority of the shares of Common Stock voted on this proposal at the meeting. Accordingly, abstentions and broker “non-votes” marked on proxy cards will not be included in the tabulation of votes cast on this proposal.

The persons named in the accompanying proxy intend to vote such proxy in favor of the ratification of the appointment of Ernst & Young LLP as independent auditors of Oceaneering for the year ending December 31, 2013, unless a contrary choice is set forth thereon or unless an abstention or broker “non-vote” is indicated thereon.

The following table shows the fees incurred by Oceaneering for the audit and other services provided by Ernst & Young LLP for 2012 and 2011.

Fees Incurred by Oceaneering for Ernst & Young LLP	2012		2011
Audit Fees (1)	$	2,345,000	$	2,346,000
Audit-Related Fees (2)		122,000		118,000
Tax Fees (3)		43,000		81,000
All Other Fees (4)		2,000		2,000
Total		2,512,000		2,547,000

(1) Audit Fees represent fees for professional services provided in connection with: (a) the audit of our financial statements for the years indicated and the reviews of our financial statements included in our Forms 10-Q during those years; and (b) audit services provided in connection with other statutory or regulatory filings.

(2) Audit-Related Fees consisted of accounting, consultation services, employee benefit plan audits, services related to due diligence for business transactions, and statutory and regulatory compliance.

(3) Tax Fees consisted of tax compliance and consultation fees.

(4) All Other Fees consisted of a subscription to Ernst & Young LLP’s informational on-line service.

The Audit Committee has concluded that Ernst & Young LLP’s provision of services that were not related to the audit of our financial statements in 2012 was compatible with maintaining that firm’s independence from us.

The Audit Committee has established a policy that requires pre-approval of the audit and non-audit services performed by our independent auditors. Unless a service proposed to be provided by the independent auditors has been pre-approved by the Audit Committee under its pre-approval policies and procedures, it will require specific pre-approval of the engagement terms by the Audit Committee. Under the policy, pre-approved service categories are generally provided for up to 12 months and must be detailed as to the particular services provided and sufficiently specific and objective so that no judgments by management are required to determine whether a specific service falls within the scope of what has been pre-approved. In connection with any pre-approval of services, the independent auditors are required to provide detailed back-up documentation concerning the specific services to be provided. The Audit Committee does not delegate to management any of its responsibilities to pre-approve services performed by our independent auditors.

41

None of the services related to the Audit-Related Fees, Tax Fees or All Other Fees described above were approved by the Audit Committee pursuant to the waiver of pre-approval provisions set forth in applicable rules of the SEC.

The Audit Committee has delegated to the Chairman of the Audit Committee the authority to pre-approve audit-related and non-audit-related services not prohibited by law to be performed by Ernst & Young LLP, provided that the Chairman is required to report any decisions to pre-approve such audit-related or non-audit-related services and fees to the full Audit Committee at its next regular meeting.

Providing voting instructions by telephone or Internet eliminates the need to return this Voting Instruction Form. Before providing your voting instructions, you should read the proxy statement and Voting Instruction Form. Please follow the steps listed on the reverse side. Your voting instructions will be promptly confirmed and posted. Thank you for participating.

(Items to be voted on appear on reverse side.)
