The Hornsea Two offshore substation (OSS) and the reactive compensation station (RCS) topsides have left the Sembcorp Marine Admiralty Yard in Singapore and are en route to the UK, Sembcorp Marine said.
The two topsides departed on 15 August and are expected to reach their destination at the end of September for the integration with their jacket foundations.
The substations were ordered by Ørsted’s subsidiary Optimus Wind Limited.
Constructed at Sembcorp Marine’s integrated facilities, the OSS and RCS have a combined weight of 10,200 tonnes.
In addition to fabrication, Sembcorp Marine was in charge of the engineering, procurement, hook-up and commissioning works for the substations.
”These Substations, along with the OSS and RCS jacket foundations that were delivered by Sembcorp Marine in August 2020, demonstrate the Group’s commitment to meet the challenge of delivering these structures safely amid this pandemic,” said Sembcorp Marine’s Head of Offshore Platforms Samuel Wong .
Located in the North Sea some 89 kilometres off the Yorkshire Coast, Hornsea Two spans an offshore area of 462 square kilometres 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.
Patrick Harnett , Senior Programme Director at Ørsted, said: ”With plans to have the wind farm operational in 2022, this is a very exciting milestone for Hornsea Two. In 2019, Ørsted opened the UK’s largest operations base for offshore wind at Grimsby’s Royal Dock, providing a total of 400 jobs for local people. Hornsea Two will be maintained and operated from this base, creating a long-term operations hubs, meaning Ørsted will provide careers for years to come – offshore wind farms last at least 25 years.”
