Partnering in practice: Deepwater pipelay Gulf of Mexico
The Mustique flowlines are dual 3-inch diameter pipelines located in 832 feet of water in Garden Banks 236. The Shasta flowlines are dual 4-inch diameter pipelines and are located in 1,040 feet of water in Green Canyon 6. A total of four pipeline end termination skids and 50 miles of pipelines were installed under a partnering agreement between the Lease Operator (Operator) and its pipeline installation contractor (Contractor). The Operator (Hardy Oil and Gas USA, Inc.) represented itself as well as one other working interest owner (Samedan Oil Corp.) in the Mustique project, and the Shasta project included a third working interest owner (Texaco Exploration and Production Inc.). The most technical challenges of the project were the laying of dual flowlines from the Contractor`s reel barge, and the installation of the flowlines past an intermediate wellhead, as was the case in the Shasta project. The installation of dual termination skids at the intermediate wellhead also required a considerable amount of technical expertise. The Operator`s objective was to achieve specific contracting goals that resulted in cost-effective work that met or exceeded the accepted quality standards of the offshore construction industry, and also to provide a means to maximize the value of each participant`s resources and expertise. Partnering, a non-bidding contracting approach, on the Shasta and Mustique projects enabled both the Operator and the Contractor to work together to share the risks involved in the installation of offshore pipelines, as well as share the savings that were realized as a function of working together.
