CONSTRUCTION work has started on a vertical pipelay system for China Offshore Oil Engineering Company (COOEC) and Dutch lifting company Huisman, the first to be owned and operated by a Chinese company.

Huisman said the tower for the 325 metre lay system, for flexible pipe, would be installed onboard offshore construction vessel HYSY286.

Together with a 400 metre deep water mast crane previously supplied by Huisman, the vessel will be sent out to deep water construction projects.

Huisman China managing director Pim Overes said the vessel showed the ambition of COOEC parent company, China National Offshore Oil Corporation.

“(It is) an ambition we would like to support now and in the future, as we feel that together with our design capacities and quality in manufacturing we can complement each other in achieving this ambition,” he said.

CNOOC spokesman Ding Donghua said this was part of a company plan to improve offshore oil and gas resource development.

“The 325 metre vertical lay system VLS is the first step to pipe flex-lay in deep sea, which is a significant milestone in realisation of the strategy of CNOOC Secondary Leap,” he said.

“CNOOC and Huisman have a very good cooperation in the field of marine engineering equipment.”

“Huisman always provides us with reliable equipment and exquisite technical service. We hope and trust that Huisman, as usual, carries forward the innovative spirit and the pursuit of excellence,” he said.
