SHANGHAI, China -- DNV is the classification society of choice for offshore projects in China, the company says. Current projects include involvement with Cosco Shipyard, Dalian Shipbuilding, Hantong Shipbuilding, Shanghai Waigaoqiao, and Yantai Raffles.

Sevan Marine's FPSO unit is under construction at both Yantai Raffles (two units) and Hantong Shipyard (one unit). Yantai Raffles is building two circular Sevan FPSO units for completion this year. TheSevan 300, with a storage capacity of 300,000 bbl can process and treat 30,000 b/d of oil and 3.6 MMcm/d of gas.

Another innovative project is the DNV-classed rig,SS Frigstad Oslo based on the Frigstad D90 design, being built at Yantai Raffles. The rig will be the largest semisubmersible ever built and will be used in ultra deepwater environments to 3,658 m (12,000 ft), DNV says. The semi has a drilling depth of 15,240 m (50,000 ft).

CNOOC and ConocoPhillips China Inc. are completing a contract with Shanghai Waigaoqiao for a 280,000 dwt FPSO hull for the Peng Lai oil field in Bohai Bay. The $200-million contract for the 310 m (1,017 ft) long, 60 m (197 ft) wide, 29 m (95 ft) deep hull, is the largest yet built in China and will have storage capacity of 2 MMbbl of oil, DNV says.

Another unique project is on order by MPF Corp. Ltd. at Cosco Dalian Shipyard – the hull of a floating, drilling, processing, storage, and offloading vessel (FDPSO).

There are also two harsh environment semisubmersible rigs for OffRig classed by DNV at Yantai Raffles, DNV says.
