Helix Reports First Quarter Results Doubling Last Year’s First
Quarter Earnings

HOUSTON, TX –Helix Energy Solutions (Nasdaq: HELX) reported first quarter net income of $55.4 million, or $0.67 per diluted share. This represents more than two times last year’s first quarter results.

Included in the earnings was a $20.7 million pre-tax charge ($0.16 per share) for the write-off of the total estimated cost to Helix for a mechanical failure in the drilling of a well at the Tulane prospect. In late March, mechanical difficulties were experienced drilling this well and, after further review and analysis, we determined the wellbore would be plugged and abandoned. Therefore, under the Company’s successful efforts method of accounting, the total estimated drilling costs to the Company were charged to earnings in the first quarter.

Despite this first quarter charge, due primarily to the continued strengthening of the contracting services markets, the Company raises the lower end of its earnings guidance estimates for 2006 to a range of $2.70 — $3.30 per diluted share.

Diluted Earnings Per Share		0.67			0.32			0.69

Owen Kratz, Chairman and Chief Executive Officer of Helix, stated, “We had a first quarter to be very proud of, except for the unexpected setback in drilling the Tulane prospect. The decision to abandon the well was a difficult one given that it was a mechanical failure as opposed to a dry hole (the reservoir could still be there). This was one of the deals closed in early 2005 in which we participated as a non-operator through a promote. It is the risk of this kind of negative impact that gave rise to the realization that we needed to be in more control and on the operator side of these arrangements. This event clearly highlights the strategic rationale for the pending acquisition of Remington Oil and Gas.

It is a testament to the strengths of our overall business model that we came close to eclipsing our record earnings of Q4/05 despite the Tulane charge. “

Financial Highlights

v	Revenues: The $132.1 million increase in year-over-year first quarter revenues was driven primarily by significant improvements in Contracting Services revenues due to the introduction of newly acquired assets and much better market conditions.
v	Margins: 35% is two points better than the year ago quarter despite the $20.7 million pre-tax charge (Tulane) taken in the first quarter of 2006. Without this charge, margins would have been 42% driven by the improved market conditions for Contracting Services.
v	SG&A: $21.0 million increased $8.2 million from the same period a year ago due primarily to increased overhead to support the Company’s growth. This level of SG&A was 7% of first quarter revenues, compared to 8% in the year ago quarter.
v	Equity in Earnings: $6.2 million reflects our share of Deepwater Gateway, L.L.C.’s earnings for the quarter relating to the Marco Polo facility as well as our share of Offshore Technology Solutions Limited’s earnings which is the Trinidadian company to which we contributed the Witch Queen.
v	Income Tax Provision: The Company’s effective tax rate for the quarter was 34.1% which is less than the 36% rate in last year’s first quarter due primarily to the Company’s ability to realize foreign tax credits due to improved profitability both domestically and in foreign jurisdictions.
v	Balance Sheet: Total debt as of March 31, 2006 was $445 million. This represents 37% debt to book capitalization and with $425 million of EBITDA during the last twelve months, this represents 1.0 times trailing twelve month EBITDA.

The improvement resulted from a full quarter of contribution from the acquisitions made last year (Stolt assets, Torch assets and Helix RDS) together with better pricing. H E L I X E N E R G Y S O L U T I O N S

Contracting Services (CS) cont. Gross profit margins improved by 15 points year over year and by six points sequentially. Most of the sequential improvement was due to the better pricing environment, with margins already reaching the top end of the forecast range for 2006. Q2/06 and Outlook: We expect further improvement in Q2/06 financial performance driven mainly by pricing. This trend should continue for at least the medium term as we add backlog on gradually better terms. H E L I X E N E R G Y S O L U T I O N S

CS - Reservoir and Well Technology First Quarter 2006 Revenues $9,605 Gross Profit 2,509 26% H E L I X E N E R G Y S O L U T I O N S Q1/06: Both revenue and gross profit were in line with our expectations for the first full quarter of business since the acquisition of Helix RDS. Q2/06 and Outlook: Activity levels are very robust and we are seeking to enter new international markets, e.g. Trinidad. The recruitment and retention of personnel is the main challenge related to achieving our earnings expectations for the full year. (Amounts in thousands, except percentages)

Q2/06 and Outlook: We expect this level of utilization to be maintained well into next year as hurricane related inspection and repair work continues. The longevity of this work is illustrated by the fact that the DSV Kestrel will commence an eighteen month contract with a major operator in June.

CS - Deepwater Construction First Quarter First Quarter Fourth Quarter 2006 2005 2005 Pipelay 100% 64% 96% Robotics 70% 66% 75% Utilization Q1/06: Pipelay asset utilization again reached 100% on the back of an exceptionally strong market for subsea tie-backs. The Express has enjoyed 98% utilization since she entered service in October. Utilization of robotic assets declined 5% sequentially due to seasonality in international operating areas and the pipe burial marketplace. H E L I X E N E R G Y S O L U T I O N S

CS - Deepwater Construction Q2/06 and Outlook: Both deepwater pipelay assets are booked through the end of the year (apart from the upgrade program for the Express which is scheduled for 45 days in Q3). The outlook is also bright for 2007 based on brisk bidding activity. The robotics group (Canyon) looks set to have another strong year with the award of several significant pipe burial contracts, together with a continued good market for ROV services. H E L I X E N E R G Y S O L U T I O N S

CS - Well Operations Q1/06: Utilization declined by 27% sequentially as both the Q4000 and Seawell had periods of unscheduled downtime. Q2/06 and Outlook: Both vessels are fully booked until the end of the year, with the Seawell in particular looking set to see at least a 10 point gross profit increase compared to 2005.

Output from this well resumed in March following a repair. At the end of the quarter daily throughput was around 40,000 boe/day from the Marco Polo wells and three K2/K2N wells. Q2/06 and Outlook: A further five wells should be brought online, from the K2/K2N and Genghis Khan fields, by the end of the year. Equity income for the full year is still expected to fall in the guidance range of $27 - $32 million. The Independence Hub is still on track for mechanical completion by the end of the year, with an enhanced production capacity of 1 bcf/day (up from 850 mmcf/day).

(Amounts in thousands, except percentages and production data)

Oil & Gas Production Q1/06: Shelf: Production of 5.4 Bcfe was 17% greater than fourth quarter due to shut-ins from Hurricanes Katrina and Rita. Realized commodity prices were down 6% overall from last quarter but 39% higher than those achieved in last year's first quarter. Natural gas made up 59% of the first quarter production. Gunnison: Production of 2.7 BCFe was up 29% over last quarter's levels due mainly to hurricane shut-ins in the 4Q/05. Natural gas made up 56% of Gunnison production in Q1. The present status of all deepwater production projects, besides Gunnison, is presented on the next two slides. H E L I X E N E R G Y S O L U T I O N S
