Keppel Wins Lingshui 17-2 Engineering Work

Keppel FloaTEC secured an engineering services contract from China’s Offshore Oil Engineering Company (COOEC), the main engineering, procurement, construction and installation (EPCI) contractor for the Lingshui 17-2 production semisubmersible to be built at COOEC's Qingdao facility in China. 

The Keppel Offshore & Marine subsidiary said its work scope includes the review and the independent design verification for the Lingshui 17-2 production semi hull, mooring, riser and deck structure.

The facility is reported to be the world’s first deepwater semi-submersible production floater with condensate storage facilities. OEdigital could not immediately confirm.

Lingshui 17-2 is in the east Lingshui Sag area of Qiongdongnan Basin, about 1,500 meters of water around 150 kilometers south of Hainan Province in South China Sea. When completed, the field will produce about 3 billion to 3.5 billion cubic meters gas per year.

CNOOC is operator with 100% interest in Lingshui 17-2. Husky has been discussing taking a minority interest in the field, according to World Energy Reports.

World Energy Reports notes a number of key contracts have been awarded for the development. In April 2017 CNOOC selected SBM to perform the production semi hull/mooring system/riser frot end engineering and design (FEED). MacGregor Cargotec has the contract to supply the mooring system. Aker Solutions has secured an NOK 1.7 billion contract to supply the subsea production system and umbilicals.

The subsea production system for the Lingshui 17-2 field will consist of 11 horizontal subsea trees, four manifolds, topside and subsea control system and a vertical tie-in connection system. According to World Energy Reports, a second phase envisages extending the subsea system from Lingshui 18-1 and Lingshui 25-2. Gas from the development will be piped to Hong Kong for power generation via an existing pipeline originating on the Yacheng 13-1 field.
