BHP, in partnership with Pemex, has selected McDermott International to provide front-end engineering design (FEED) of a semisubmersible floating production unit (FPU) for the Trion project in the Gulf of Mexico. The FPU will be designed for a water depth of approximately 8,200 ft and is destined for the Trion field, 19 miles south of the US/Mexico maritime border and about 112 miles off the Mexican coastline. The design contract was awarded following a 14-month design competition, which was preceded by a competitive tender process. Building upon the pre-FEED work previously completed by McDermott, the FEED study work will focus on the development of an FPU design with a nameplate capacity of 100,000 B/D of oil. The scope of the FEED contract includes engineering tasks related to the configuration, sizing, and analysis of the FPU, including topsides, hull, risers, and mooring.
