McDermott has completed the Scarborough floating production unit (FPU) floatover project for Woodside Energy.

This milestone encompasses the fabrication, construction and offshore installation of the FPU topside and hull structures.

The contract, awarded in 2021, extended McDermott's involvement with the Scarborough Energy Project following the front-end engineering design (FEED) of the FPU.

The project's scope includes comprehensive engineering, procurement, construction, installation and commissioning services.

McDermott has undertaken the design, fabrication, integration, transportation and installation of the FPU, which features a topside of approximately 30,000 tonnes (t) and a 37,000t hull structure.

The company said this FPU is not only the largest that McDermott has ever designed and constructed but also ranks among the most significant semi-submersible production platforms in offshore history.

The topsides were fabricated at McDermott's joint venture yard, Qingdao McDermott Wuchuan, in Qingdao, China. Concurrently, the hull was constructed by COSCO at its Qidong shipyard.

The topsides boast six deck levels and are equipped with 169 core equipment units including three gas turbine-driven export gas compressors and three main generators with waste heat recovery systems.

The facility also includes more than 50,000m of piping, one million metres of cabling, 568 integrated subsystems and a battery energy storage system to support emissions reduction efforts.

Earlier this month, the topsides and hull were transported offshore and the topsides were installed onto the hull via a floatover operation off the coast of Dalian, China.

Post-floatover, the FPU reached CIMC's Raffles yard in Yantai, China, for the final integration works.

The next phase will see the FPU sail to Western Australia to be moored at the Scarborough gas field roughly 375km offshore from the Burrup Peninsula.

Additionally, McDermott has also secured an enterprise framework agreement (EFA) with Shell Global Solutions International.

Spanning an initial three years with options for two additional one-year extensions, the EFA encompasses engineering and procurement services across McDermott's Low Carbon Solutions, Offshore Middle East, and Subsea and Floating Facilities divisions.
