The China National Offshore Oil Corporation (CNOOC) has awarded contracts to Aker Solutions to deliver power umbilical systems to Liuhua oil fields located offshore Hong Kong.

Under the contract valued at more than Nkr350m ($41.4m), Aker will provide over 35km of dynamic and static power umbilicals for the Liuhua 16-2, 20-2 and 21-2 fields in the South China Sea.

The umbilicals will link the subsea development to a new floating production, storage and offloading (FPSO) unit.

Aker Solutions CEO Luis Araujo said: “We are honoured to work with CNOOC again to demonstrate our capabilities in China.

“Liuhua is an important project and we look forward to providing umbilicals, which meet its long-distance power transmission requirements.”

The bundled cable and fibre optic umbilical systems provide distribution of power, control and communication between subsea equipment on the seafloor and platforms or floating production facilities.

Aker will engineer the static section of the Liuhua 16-2 umbilical using its advanced manufacturing process called OsciLay.

“OsciLay allows us to manufacture extremely long or heavy power umbilicals, which will otherwise be limited using conventional manufacturing approaches.”

Aker Solutions Asia Pacific subsea sales vice-president Greg Ross said: “OsciLay is a unique manufacturing method, which addresses challenges of more extreme tension loads during installation, eliminating splicing of cables due to manufacturing weight limitations.

“OsciLay allows us to manufacture extremely long or heavy power umbilicals, which will otherwise be limited using conventional manufacturing approaches.”
Aker Solutions’ global facilities will be involved in the project.

The engineering work will be led by the company’s team in Malaysia, while production and manufacturing will take place at its umbilical production facility in Mobile, Alabama, US.

Project for Liuhua 16-2 and 20-2 fields offshore Hong Kong is expected to be delivered by the end of next year, and for Liuhua 21-2 in 2020.

Initially in 2010, Aker Solutions worked on a subsea project with CNOOC. Since then, the company has provided the subsea production system for Liuhua 19-5 and Yacheng 13-4 gas fields.
