Hornsea Two OSS and RCS Design All Done

Semco Maritime and ISC Consulting Engineers have completed the design of the offshore substation and the Reactive Compensation Station (RCS) for the Hornsea Project Two offshore wind farm.

The fabrication of the two structures will take place at Sembcorp Marine’s integrated yard facilities in Singapore, as part of a recently signed contract.

Once completed, the project’s substation is expected to set a record with a 1,320MW capacity and a 7,500t topside installed on a six-legged jacket foundation.

Ørsted awarded Semco Maritime with a contract at the end of last year to develop electrical and mechanical basic engineering design of the Hornsea Two offshore substation and RCS.

The 1.4GW Hornsea Project Two offshore wind farm will feature 165 Siemens Gamesa 8MW turbines installed some 89km from the Yorkshire coast in the UK.

It will become the world’s biggest offshore wind farm when operational in 2022, leapfrogging the 1.2GW Hornsea Project One, currently being constructed 120km offshore Yorkshire.
