Subsea 7 S.A. has been awarded an EPCI topside contract valued at approximately $150 million from Chevron for the development of the Lianzi field offshore the Republic of Congo and Angola.
The scope of work includes a 200mT module hosting a high voltage generation system for the new subsea Direct Electrically Heated pipeline cable, a 80mT flow meter deck extension, and various upgrades on the platform. Project execution will maximize the use of local personnel and resources in the Republic of Congo and Angola. Onshore fabrication will be performed in both the Republic of Congo and Angola by Subsea 7’s Angolan joint venture. The offshore works, including installation, hook-up and commissioning, are scheduled for the second half of 2014.
Olivier Carre, Senior Vice President for Subsea 7’s Africa and Gulf of Mexico Territory, said: “Following the award to Subsea 7 earlier this year of the subsea installation works for the Lianzi development, we are proud of the award of the topsides modifications works, which demonstrates our proven capabilities in the offshore hook-up and revamping segment”.
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).
