COOEC issues tender for Lingshui 17-2

TechnipFMC and Subsea 7 among contractors invited to bid for installation of facilities at project in South China Sea

China's Offshore Oil Engineering Company (COOEC) is seeking a sub-contractor to work on the installation of deep-water facilities for the Lingshui 17-2 deep-water gas play in the South China Sea.

COOEC, via its COOEC Subsea unit, late last week issued a tender for the installation of mooring piles, umbilicals, terminals and other subsea structures for the Lingshui gas field.

“An invitation to tender was issued last Friday to a number of foreign contractors including TechnipFMC and Subsea 7,” said one source, adding that Saipem of Italy was not ready to participate - in part due to vessel commitments to other projects.

Bids are due to be submitted by 26 August for the work that is expected to start early in the second quarter of 2020 and will last four months.

The award could be made as soon as early September and the winner is expected to base its project team in Shenzhen in mid-September.

The vessel to be used on the job should have no more than 15 years in service and be equipped with a dynamic positioning system and two heavy work remotely-operated underwater vehicles.

The workscope includes installing 15 subsea mooring piles, four deep-water manifolds, two subsea umbilical termination units, one subsea distribution unit and five umbilicals.

Qualified bidders should have a track record of subsea umbilical, riser and flowline, and pipe installation.

Meanwhile, COOEC has shortlisted Saipem and Subsea 7 in the competition to provide a vessel to install steel catenary risers linked to Lingshui’s semi-submersible production platform.

COOEC in recent days has been holding individual sessions with Saipem and Subsea 7 as a final clarification exercise.

Located in the Qiongdongnan basin near the island of Hainan in the South China Sea, and in water depths of up to 1560 metres, the Lingshui 17-2 development includes a subsea production system covering 11 wells, with one manifold in the west and three in the east, all tied back to a large semi-submersible platform.

Oslo-listed Aker Solutions earlier won a contract to supply 11 horizontal trees, four manifolds, topsides, a subsea control system and more than 70 kilometres of umbilicals.

Operator CNOOC Ltd initially targeted first gas from Lingshui at the end of 2020, with preliminary output expected to be about 3.3 billion cubic metres per annum of gas and 1400 cubic metres per day of condensate. However, first gas is now more likely to flow in 2021.
