HOUSTON, Aug. 25 -- Chevron USA Inc. has let a contract to a J. Ray McDermott SA subsidiary for installation of infield flowlines, associated pipeline connections, and steel catenary risers (SCRs) for the Tahiti development in the Green Canyon area of the Gulf of Mexico.

The Tahiti development includes a truss spar on Block 641 in 4,000 ft of water, production drilling facilities on Blocks 596 and 640, and a discovery well on Block 640 that Chevron said could produce as much as 30,000 b/d of oil (OGJ Online, Oct. 20, 2004).

McDermott will install two 6-in. and four 9-in. flowlines with associated pipeline end terminations (PLETs), a PLET assembly near the drill center manifold, including static flowline segments and in-line buoyancy, which will transition into an SCR terminating at the Tahiti spar. Derrick Barge 50 will perform the work in 2007.

Chevron and partners EnCana Gulf of Mexico LLC and Shell Gulf of Mexico Inc. will decide early in 2006 the contractor for installation of manifolds on Blocks 596 and 640 and an additional gravity-based tie-in sled adjacent to the discovery well.
