After successfully completing the FEED for the Scarborough project, McDermott has been awarded a contract by Woodside, as Operator for and on behalf of the Scarborough Joint Venture, for the engineering, procurement, construction, installation and commissioning (EPCIC) services for its Floating Production Unit (FPU) offshore Western Australia. The integrated scope also includes the design, fabrication, integration, transportation and installation of the hull and topsides.
The topside, which will be approximately 30 000 t, will be fabricated by McDermott's joint venture fabrication yard, Qingdao McDermott Wuchuan, in China. The project scope includes a battery energy storage system to reduce emissions on the topsides and support Woodside's net emissions reduction targets.
The FPU processes natural gas, which includes gas separation, dehydration and compression as well as mono ethylene glycol regeneration and produced-water handling. Designed for a production capacity of up to 1.8 billion standard cubic feet per day, the topside will be connected to the semi-submersible hull and pre-commissioned prior to transportation and installation in a water depth of 3100 ft (950 m), approximately 248 miles (400 kilometers) offshore Western Australia. The FPU will be capable of being remotely operated and minimally staffed during normal production operations.
In Qatar, McDermott will deliver engineering, procurement, construction and installation (EPCI) for the North Field East (NFE) Topsides and the North Field East (NFE) Offshore Pipelines and Subsea Cables projects, with an option included to also award the North Field South (NFS) Offshore Topsides—representing one of the largest single contracts McDermott has been awarded in its company history.
The NFE development will provide feed gas into the four new LNG Trains currently under construction and, together, with the NFS infrastructure, which will provide feed gas for the future additional two LNG trains, will enable an increase in total LNG production in Qatar from 77 million tpy to 126 million tpy.
The scope of the contract includes the fabrication and installation of eight wellhead topsides (WHT) for NFE and a further five WHT for NFS. The significant subsea pipeline scope includes over 300 miles (500 km) of pipelines and, in addition, McDermott will install over 140 miles (225 km) of 33kV subsea cables and associated works. For the first time, four of these WHT, plus all subsea infrastructure, will be fabricated in QFAB, improving the in-country execution platform to support future energy developments. The remaining fabrication will be done in collaboration with McDermott's facility in Batam, Indonesia.
