COOEC will begin commissioning the vessel in early 2011, before delivering it to a field in the South China Sea in the second half of 2011.

The commissioning is being undertaken in preparation for CNOOC’s deep-water pipelay service duties at Husky’s Liwan 13-1 Gas Field in the South China Sea.

COOEC will be the operator of the $US439 million vessel, which has a lifting capacity of 4000 t and is capable of functioning in water depths of up to 3,000 m. The unit has the capacity to lay 5 km of subsea pipelines per day.

The Haiyangshiyou 201 was built by Jiangsu Rongsheng Heavy Industries, in Rugao city, Jiangsu province.
