Aker Solutions has received contracts to deliver power umbilical systems to China National Offshore Oil Corporation's (CNOOC) Liuhua oil fields in the South China Sea.
Under the NOK350m ($41m) contracts, Aker will be responsible for the supply of 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.
Aker Solutions CEO Luis Araujo said: “Liuhua is an important project and we look forward to providing umbilicals which meet its long-distance power transmission requirements.”
The power umbilical systems are bundled cable and fiber optic systems intended to provide distribution of power, control and communication between subsea equipment on the seafloor and platforms or floating production facilities.
Aker’ advanced manufacturing process called OsciLay is planned to be used for engineering the static section of the Liuhua 16-2 umbilical.
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’ team in Malaysia will lead the engineering work. The firm plans to undertake production and manufacturing at its umbilical production facility in Mobile, Alabama in the US.
The delivery to the Liuhua 16-2 and 20-2 fields is planned for the end of 2019, while the Liuhua 21-2 delivery is set for 2020.
Aker Solutions had earlier provided subsea production system for Liuhua 19-5 and Yacheng 13-4 gas fields.
Earlier this year, TechnipFMC won a subsea contract by CNOOC for the Liuhua 16-2, 20-2 and 21-2 oilfield joint development project in the South China Sea.
The contract scope includes the engineering, procurement and construction of subsea equipment, including 26 units of Enhanced Horizontal Christmas Trees (EHXT) as well as wellheads, subsea control systems, manifolds, tie-in systems and intervention workover control systems (IWOCS).
