Subsea 7 was awarded an engineering, procurement, installation, and commissioning (EPIC) subsea umbilical, riser, and flowline (SURF) contract valued at approximately US $600 million from Chevron Overseas Congo for the development of the Lianzi field offshore Congo and Angola.
The technical specifications include a 4-m (12-ft) wet insulated production flow-line with direct electrical heating, which would set a record for the deepest electrically heated pipe. The project will maximize the use of local personnel and resources in Congo and Angola. A significant part of the design and fabrication will be executed in Luanda, with additional fabrication work carried out in Lobito by Subsea 7’s Angolan joint venture.
All flow-lines will be spooled to the rigid reel-lay ship the Seven Oceans at Subsea 7’s Luanda base in Angola.
Angolan and Congolese personnel will join the offshore construction teams during the offshore phase which is scheduled for the second half of 2014.
