Accounting Policies [Abstract]
USE OF ESTIMATES	NOTE 3—USE OF ESTIMATES We use estimates and assumptions to prepare our financial statements in conformity with U.S. GAAP. Those estimates and assumptions affect the amounts we report in our consolidated financial statements and accompanying notes. Our actual results could differ from those estimates, and variances could materially affect our financial condition and results of operations in future periods. Changes in project estimates generally exclude change orders and changes in scope, but may include, without limitation, changes in cost recovery estimates, unexpected changes in weather conditions, changes in productivity, unidentified required vessel repairs, customer and vendor delays and other costs. We generally expect to experience a reasonable amount of unanticipated events, and some of those events can result in significant cost increases above cost amounts we previously estimated. As of June 30, 2015, we have provided for our estimated costs to complete on all our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results. For all contracts, if a current estimate of total contract cost indicates a loss, the projected loss is recognized in full when determined. The following is a discussion of our most significant changes in estimates that impacted operating income for the three and six months ended June 30, 2015 and 2014. Three months ended June 30, 2015 Operating income for the three months ended June 30, 2015 was positively impacted by net favorable changes in cost estimates totaling approximately $7.3 million across all segments. The AEA segment was positively impacted by net favorable changes in estimates aggregating approximately $3.4 million, primarily due to reduced cost estimates attributable to the contract close-out process associated with the Papa Terra EPCI project in Brazil. The MEA segment had net favorable changes in estimates aggregating approximately $0.6 million. A project in Saudi Arabia was positively impacted by $7 million due to productivity improvements and associated cost savings on the Intermac 406 vessel, which is working on a cable lay project. These favorable changes were partially offset by a $4.9 million increase in pipelay cost estimates on a U.A.E. project, primarily due to changes in execution plan, and $1.5 million of unfavorable change in estimates for multiple projects. The ASA segment was positively impacted by net favorable changes in estimates and productivity bonuses earned totaling approximately $3.3 million, driven by multiple projects, none of the individual results of which were material. Six months ended June 30, 2015 Operating income for the six months ended June 30, 2015 was positively impacted by net favorable changes in cost estimates totaling approximately $28.9 million across all segments. The AEA segment was positively impacted by net favorable changes in estimates aggregating approximately $10.0 million. Improvements primarily related to reduced cost estimates of approximately $3.4 million attributable to the Papa Terra project, $3.8 million due to productivity improvements on the Agile charter and reduced cost estimates of $3.6 million attributable to a revised demobilization plan for one of our vessels, the North Ocean 105 (the “NO 105”), which is working on a subsea project in Brazil, partially offset by unfavorable impact of $0.8 million driven by multiple projects. The MEA segment was positively impacted by net favorable changes in estimates aggregating approximately $9.7 million. One EPCI project in Saudi Arabia was positively impacted by $6.9 million due to changes in revenue recovery and cost savings based on agreement with a customer on design optimization. . Another project in the U.A.E. improved by $4.8 million as a result of an agreement with the customer on compensation for vessel downtime due to weather and standby delays. A project in Saudi Arabia was positively impacted by $7.4 million of changes mostly due to productivity improvements and associated cost savings on the Intermac 406, which is working on a cable lay project. We also had favorable changes of $1.3 million from multiple projects, none of the individual results of which were material. These favorable changes were partially offset by a $5.8 million negative impact on another EPCI project in Saudi Arabia, primarily due to increase in cost estimates, as a result of a change in marine execution plans, and a $4.9 million increase in pipelay cost estimates on a U.A.E. project, as a result of changes in execution plan. The ASA segment experienced an improvement of approximately $9.2 million, driven by multiple projects, none of the individual results of which were material, primarily due to favorable changes in estimates. Three months ended June 30, 2014 Operating income for the three months ended June 30, 2014 was positively impacted by $24.4 million of net favorable changes in cost estimates. The AEA segment deteriorated by a net $13.4 million from changes in estimates on three projects. On the PB Litoral project, we increased our estimated costs to complete by approximately $20 million, primarily due to projected fabrication cost increases, reflecting reduced productivity and execution plan changes to mitigate further project delays, as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On Jack & St. Malo, a subsea project in the Gulf of Mexico, we increased our estimated costs to complete by approximately $23.3 million, primarily due to equipment downtime issues on the North Ocean 102 (the “NO102”), our primary vessel working on the project. This project was completed in the third quarter of 2014. These negative impacts were partially offset by approximately $30 million of project close-out improvements on the Papa Terra project, which was completed in 2014, from marine cost reductions and increased recoveries due to successful developments from an approval process for additional weather-related compensation. The MEA segment experienced net favorable changes in estimates aggregating approximately $22 million, primarily due to increased cost recovery estimates of approximately $29.2 million on a pipelay project in the Caspian, which was completed in 2014. The increased cost recovery estimates were based on positive developments during the three months ended June 30, 2014 from a project close-out process with the customer. This improvement was partially offset by $7.2 million of increased estimated costs to complete an EPCI project in Saudi Arabia, mainly for the onshore scope of the project. The ASA segment was positively impacted by net favorable changes in estimates aggregating approximately $15.8 million, mostly due to reduced cost estimates on the Siakap Subsea Development (“Siakap”), a subsea project in Malaysia, which was completed in 2014, of approximately $10.2 million during the three months ended June 30, 2014. Those reduced cost estimates were primarily related to project close-out savings on marine spread and procurement costs. In addition, completion of three smaller projects resulted in project close-out savings of approximately $5.6 million. Six months ended June 30, 2014 Operating income for the six months ended June 30, 2014 was negatively impacted by $21.2 million of net unfavorable changes in cost estimates. The AEA segment was negatively impacted by net unfavorable changes in estimates aggregating approximately $39.3 million associated with four projects. On the PB Litoral project, we increased our estimated costs to complete by approximately $55.4 million due to liquidated damages and extended project management costs arising from project delays, projected fabrication cost increases reflecting reduced productivity and execution plan changes to mitigate further project delays, as well as procurement and marine installation cost increases. This project is in a loss position and is estimated to be completed in the fourth quarter of 2015. On the Jack & St. Malo project, we increased our estimated costs to complete by approximately $22.5 million, primarily due to equipment downtime issues on the NO102, our primary vessel working on the project. This project was completed in the third quarter of 2014. These negative impacts were partially offset by $33.7 million of project close out improvements on the Papa Terra project, from marine cost reductions upon completion of activities and increased recoveries due to successful developments from an approval process for additional weather-related compensation. We also recognized $4.9 million of cost reductions, mainly due to project close-out improvements on Tubular Bells Gulfstar, a marine installation project in the Gulf of Mexico. The MEA segment was negatively impacted by net unfavorable changes aggregating approximately $12.7 million, due to changes in five projects in the region. On three EPCI projects in Saudi Arabia, we increased our estimated cost at completion by approximately $35.3 million, primarily as a result of vessel downtime due to weather and standby delays, reduced productivity levels and increased cost estimates to complete the onshore scope of one of the projects. On another EPCI project in Saudi Arabia, we increased our overall estimated costs to complete by approximately $6.6 million related to (1) the onshore work which was substantially completed in July 2014 and (2) delays in completing the offshore work, due to limited access to the project site, which was caused by schedule conflicts with another contractor. These negative changes were partially offset by approximately $29.1 million of increased cost recovery estimates on a pipelay project in the Caspian, based on positive developments during the six months ended June 30, 2014 from the project close-out process with the customer. The ASA segment experienced net favorable changes in estimates aggregating approximately $30.8 million, mostly due to changes in estimates on the Siakap project, during the six months ended June 30, 2014. Those changes were primarily related to productivity improvements on our marine vessels and offshore support activities, as well as project close-out savings.
