HOUSTON, Aug. 27 -- Paris-based Technip-Coflexip's US unit, Technip Offshore Contractors Inc.—formerly Coflexip Stena Offshore Inc.—received two contracts for installation of deepwater pipelines in the Gulf of Mexico. Both projects will be accomplished using the company's new CSO Deep Blue ultradeepwater pipelay and construction vessel:

-- TotalFinaElf SA subsidiary TotalFinaElf E&P USA Inc. and Chevron Pipe Line Co. awarded a contract for the installation of two 15.8 mile, 8-in. and 10-in. pipelines and an associated reeled steel catenary riser in Matterhorn field. The field is on Mississippi Canyon Block 243 in 2,816 ft of water.

The pipelines will extend from a tension leg platform to a subsea tie-in with existing pipelines. Installation is scheduled for completion in the fourth quarter.

-- BP America Production Co. awarded a contract for fabrication and installation of a subsea pipeline in its King West development. King West is on Mississippi Canyon Block 84 in water 1,655 m deep.

The single pipe-in-pipe, passively insulated flowline will consist of 3.5 km of 6-in. pipe within a 10-in. pipe. The pipe stalks, in 5,000 ft lengths, will be fabricated onshore, welded, and spooled onto the pipelay vessel's reel for installation. The flowline will tie back the King West well from a point near the well to an existing subsea tie-in base associated with the producing King subsea flowline system.

Construction is slated for April 2003.
