Aker Solutions has won orders valued at more than US$41.6 million (NOK 350 million) to deliver power umbilical systems to China National Offshore Oil Corporation's (CNOOC) Liuhua oilfields in the South China Sea, off Hong Kong.
The work scope includes more than 35km of dynamic and static power umbilicals for the Liuhua 16-2, 20-2 and 21-2 fields, linking the subsea development to a new floating production, storage and offloading (FPSO) unit.
"We are honoured to work with CNOOC again to demonstrate our capabilities in China," said Luis Araujo, chief executive officer of Aker Solutions. "Liuhua is an important project and we look forward to providing umbilicals which meet its long-distance power transmission requirements."
Power umbilical systems are bundled cable and fiber optic systems providing distribution of power, control and communication between subsea equipment on the seafloor and platforms or floating production facilities. The static section of the Liuhua 16-2 umbilical will be engineered using Aker Solutions' advanced manufacturing process called OsciLay.
Project delivery is set for the end of 2019 for Liuhua 16-2 and 20-2, and in 2020 for Liuhua 21-2.
"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," said Greg Ross, Aker Solutions' vice president of subsea sales in Asia Pacific. "OsciLay allows us to manufacture extremely long or heavy power umbilicals which will otherwise be limited using conventional manufacturing approaches."
