Subsea 7 S.A. has been awarded an EPIC SURF contract valued at approximately $600 million from Chevron for the development of the Lianzi field, located in a unitized offshore zone between the Republic of Congo and the Republic of Angola.
The technical specifications include a 12” 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.
Olivier Carre, Senior Vice President for Subsea 7’s Africa and Gulf of Mexico Territory , said: “We are very pleased to be awarded this EPIC contract including the design and procurement of the subsea facilities which fits perfectly with Subsea 7’s capacity to deliver large scale projects. We look forward to working in close cooperation with Chevron to deliver the Lianzi project safely and to the highest standards.”
Lianzi
Located 65 miles (105 km) offshore in approximately 3,000 feet (900 meters) of water, the Lianzi field will be developed via a tieback to the existing Benguela Belize Lobito Tomboco (BBLT) platform located in Angola Block 14.
The $2.0 billion development will include a subsea production system and a 27 mile (43 km) electrically heated flowline – the first of its kind at this water depth – to transport the oil from the field to the BBLT platform. First oil is expected in 2015. Once completed, the project is expected to produce a maximum of 46,000 barrels of oil equivalent per day.
Chevron Overseas Congo Limited is operator of the Lianzi field and has a 31.25 percent interest, along with Total (36.75 percent), ENI (10 percent), Sonangol (10 percent), SNPC (the Republic of Congo National Oil Company – 7.5 percent), and GALP (4.5 percent).
