HOUSTON, Feb. 21 -- Chevron Corp. contracted Subsea 7 SA for the engineering and installation of the Tahiti Phase 2 development in about 4,000 ft of water in the Gulf of Mexico, about 190 miles south of New Orleans.
Subsea 7's workscope includes the installation of one 7.5-in. by 13,000 ft long flexible riser, one 4-in. by 4,500 ft long umbilical, five rigid well jumpers, 10 electrical flying leads, and seven steel flying leads.
It also will transport the flexible riser from Le Trait, France to the Gulf of Mexico and commence immediately the engineering work at its Houston office. Plans are to install the flexible riser and umbilical in third-quarter 2011 and tie in five wells through mid 2012.
