Study To Evaluate Tanker-Based FPSO For Gulf Of Mexico

Brain Watt Associates, Inc.

(BWA) of Houston, Texas, in conjunction with H.O. Mohr & Associates, Inc., Coflexip & Services, Inc., and Noble, Denton & Associates, Inc. has announced the initiation of a joint industry study assessing a tanker-based floating production, storage, and offloading system (FPSO) for the Gulf of Mexico. The eight-month project is being sponsored by seven oil companies. Primary focus of the study is the large number of deepwater leases that are remote from existing pipeline infrastructure. The study will address the development of an inexpensive production system in terms of initial costs, operation, and maintenance. Key technical issues are the risers, mooring system, fluid swivels, and the riser-tanker interface. Study criteria include system installation in water depths of 3,000 feet and production of 15,000 BOPD from eight wells.

BWA will utilize its new RISCOM/ FREECOM time domain and frequency domain riser analysis program library in the design of the riser systems. BWA personnel with hands-on experience with tankerbased systems and projects in the Philippines, Brazil and the North Sea will be coordinating this effort. This project follows the successful completion of a 10-month study involving the use of semisubmersiblebased floating production systems for deepwater Gulf of Mexico leases.

Completion of the tanker FPSO project is targeted for July 1986, and will provide the operator with a data base from which FPSO systems can be evaluated for site specific application. The cost of the project is $43,000 per company.

Additional interested parties are welcome to join the program and should call Rick Davis at Brian Watt Associates, Inc. (713) 590- 9955.
