Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies And Other Matters	Commitments and Contingencies and Other Matters Commitments In March 2012, we executed a contract with a shipyard in Singapore for the construction of a newbuild semi-submersible well intervention vessel, the Q5000. This $386.5 million shipyard contract represented the majority of the costs associated with the construction of the Q5000. Pursuant to the terms of this contract, payments were made as a fixed percentage of the contract price, together with any variations, on contractually scheduled dates. The vessel was delivered to us in the second quarter of 2015 and is currently in transit to the Gulf of Mexico. In September 2014, we entered into the Nordea Credit Agreement to partially finance the construction of the Q5000 and other future capital projects. The Nordea Term Loan was funded at the time the Q5000 vessel was delivered to us (Note 6). At June 30, 2015, our total investment in the Q5000 was $479.0 million, including $386.5 million of scheduled payments made to the shipyard. In February 2013, we contracted to charter the Grand Canyon II and the Grand Canyon III for use in our robotics operations. The terms of the charters are for five years from the respective delivery dates. We took delivery of the Grand Canyon II in late April 2015 and received a $4.7 million non-refundable payment from the shipyard that constructed the vessel related to the delayed delivery of the vessel. This payment will be amortized as a reduction in our cost of sales over the five-year charter for the vessel. The delivery of the Grand Canyon III has been extended until February 2016. In September 2013, we executed a second contract with the same shipyard in Singapore that constructed the Q5000. This contract is for the construction of a newbuild semi-submersible well intervention vessel, the Q7000, which is to be built to North Sea standards. This $346.0 million shipyard contract represents the majority of the expected costs associated with the construction of the Q7000. Pursuant to the original terms of this contract, 20% of the contract price was paid upon the signing of the contract and the remaining 80% was to be paid upon the delivery of the vessel. Pursuant to an amendment we entered into with the shipyard in June 2015, the remaining 80% will now be paid in two installments, with 20% in June 2016 and 60% upon the delivery of the vessel. We agreed to pay the shipyard incremental costs of up to $14.5 million to extend the scheduled delivery of the Q7000 from mid-2016 to July 30, 2017. We paid $7.3 million of these costs in July 2015 and the remaining costs will be paid upon the delivery of the vessel. At June 30, 2015, our total investment in the Q7000 was $105.8 million, including the $69.2 million paid to the shipyard upon signing the contract. In February 2014, we entered into agreements with Petróleo Brasileiro S.A. (“Petrobras”) to provide well intervention services offshore Brazil. The initial term of the agreements with Petrobras is for four years with options to extend. In connection with the Petrobras agreements, we entered into charter agreements with Siem Offshore AS for two newbuild monohull vessels, both of which are expected to be in service for Petrobras in 2016. At June 30, 2015, our total investment in the topside equipment for the two vessels was $85.7 million. In November 2014, we paid a charter fee deposit of $12.5 million. Contingencies and Claims We believe that there are currently no contingencies which would have a material effect on our financial position, results of operations or cash flows. Litigation We are involved in various legal proceedings, some involving claims for personal injury under the General Maritime Laws of the United States and the Jones Act based on alleged negligence. In addition, from time to time we incur other claims, such as contract disputes, in the normal course of business.
