McDermott has announced the safe, successful completion of fabrication, construction, and offshore floatover of the Scarborough floating production unit (FPU) topside and hull structures for Woodside Energy.
The contract, awarded in 2021, followed the successful delivery of front-end engineering design for the Scarborough Energy Project's FPU and includes engineering, procurement, construction, installation and commissioning (EPCIC) services. McDermott is delivering design, fabrication, integration, transportation and installation of an approximately 30 000 t topside and 37 000 t hull structure, making it the largest floating production facility the company has ever designed and built, and one of the largest semi-submersible production platforms built in offshore history.
Topsides fabrication was completed at McDermott's joint venture yard, Qingdao McDermott Wuchuan (QMW), in Qingdao, China, while the hull was constructed by COSCO in its Qidong shipyard, also in China. The topsides have six deck levels; 169 core equipment units, including three gas turbine-driven export gas compressors and three main generators with waste heat recovery systems; more than 50 000 m of piping; one million meters of cabling; 568 integrated subsystems and a battery energy storage system, supporting operational emissions reduction.
Earlier this month, both structures were transported offshore, and the topsides installed onto the hull via floatover off the coast of Dalian, China.
Following the successful floatover, the FPU arrived at CIMC's Raffles yard in Yantai, China, for final integration works. From there, it is expected to sail away to Western Australia, where it will be moored at the Scarborough gas field approximately 375 km offshore from the Burrup Peninsula.
