Under the contract, McDermott will be responsible for the engineering, procurement, construction, installation and commissioning (EPCIC) services for the FPU.
The scope of works also includes the designing, fabrication, integration, transportation and installation of the hull and topsides of the FPU.
The contract award follows the completion of the front-end engineering design for the project.
With a production capacity of up to 1.8 billion standard cubic feet per day, the topside will be connected to the semi-submersible hull.
It will be installed in a water depth of 3,100ft, approximately 248 miles offshore Western Australia.
Equipped to process natural gas, the FPU can be remotely operated. It also requires minimal staffing during normal production operations.
McDermott executive vice-president and chief operating officer Samik Mukherjee said: “McDermott brings the engineering and execution expertise to deliver integrated deepwater subsea projects and offshore FPUs to the highest standards.
“The facilities incorporate energy efficiency into its design to reduce Scarborough’s offshore emissions.”
McDermott plans to fabricate the 30,000t topside at its joint venture fabrication yard, Qingdao McDermott Wuchuan, in China.
A battery energy storage system will be installed to reduce emissions on the topsides.
McDermott’s subsea team in Perth, Australia, will support the transportation, installation, hook-up and commissioning activities for the project.
