Subsea 7 has been awarded an engineering and installation contract by Chevron USA for the Tahiti Phase 2 development in the Gulf of Mexico.
The Subsea 7 workscope is to install one 19-centimetre by 4,000-metre long flexible riser, one 10-centimetre by 1,400-metre long umbilical, five rigid well jumpers, 10 electrical flying leads (EFL) and seven steel flying leads (SFL). Subsea 7 will also transport the flexible riser from Le Trait, France to the Gulf of Mexico.
The installation of the flexible and umbilical will take place during third quarter 2011 with the five well tie-ins occurring through to mid-2012. Subsea 7 will be utilising the 'Seven Oceans' (pipelay) 'Skandi Neptune' (construction/flexlay), and the 'Ross Candies' (light construction/IMR) vessels for the installation.
The Tahiti Phase 2 work is located in Green Canyon 640 and is approximately 190 nautical miles south of New Orleans in water depths over 1,200 metres. Chevron holds a 58 percent working interest in Tahiti and is the operator.
