Sofia substation installation completed
UK, England: RWE’s contractor Heerema has completed the installation of the offshore substation for the 1400 MW Sofia Offshore Wind Farm off the UK coast. The installation on site was carried out with the heavy-lift vessel Sleipnir as a subcontractor of the consortium between GE Vernova and Seatrium.
The platform is as tall as an 11-storey building and weighs 13000 tons. It was lifted onto the jacket foundation structure, and RWE has claimed is the largest lift in the history of offshore wind energy. The substation took two and a half years to build. High-voltage direct current (HVDC) technology improves the efficiency in power transmission from the project to shore via a 220 km cable route.
The offshore substation was realised as a joint project between RWE, GE Vernova and Seatrium. It is located 200 km off the UK’s north-east coast on the Dogger Bank in the North Sea and is anticipated to be fully operational in 2026.
Sven Utermohlen, CEO RWE Offshore Wind, commented: “The successful installation of the Sofia offshore substation, the largest of its kind, is a milestone in the construction of our offshore wind farm and for the offshore wind industry. Building a project of this size and scale is a great opportunity to demonstrate our expertise and partnership excellence in the expansion of offshore wind.”
Once completed, the project will produce electricity from 100 14MW Siemens Gamesa wind turbines, while the electricity will be transported via subsea cables to Redcar, Teesside.
