Sembcorp Marine sends substations for 1.4 GW Hornsea 2 Project offshore wind project

Sembcorp Marine has completed the fabrication of the Offshore Substation (OSS) and Reactive Compensation Station (RCS) for Ørsted Wind Power subsidiary Optimus Wind Limited. The substations have set off on a voyage to the Hornsea Two Offshore Wind Farm from Sembcorp Marine Admiralty Yard.

Constructed at Sembcorp Marine’s integrated facilities, the OSS is the largest AC offshore substation and together with the RCS, they have a combined weight of 10,200 tonnes. In addition to fabrication, Sembcorp Marine spearheaded the engineering, procurement, hook-up, and commissioning works for the substations.

Located in the North Sea some 89 km off the Yorkshire Coast, Hornsea Two spans an offshore area of 462 km2 and will be the world’s largest wind farm when it goes into operation in 2022. With a capacity of 1.4 GW, the farm will provide power to more than 1.3 million homes in the United Kingdom.

The substations will reach their destination at end-September 2021 for integration with their jackets. Installation of the OSS and RCS jacket foundations was completed in October 2020.
