The offshore substation topside for RWE’s 1-gigawatt (GW) Thor wind farm has been successfully installed off the coast of Denmark, marking a key construction milestone for what will become the country’s largest offshore wind facility.
The topside was transported from the HSM Offshore yard in Schiedam, the Netherlands, and lifted into position by the heavy-lift vessel Gulliver, operated by Scaldis SMC. The installation follows the earlier placement of the jacket foundation at the site.
“This installation marks a key step in our full EPCIC contract delivery for the Thor project, including engineering, procurement, construction, installation, and commissioning of both jacket and topside,” an HSM Offshore spokesperson said.
Developed by RWE in partnership with Norges Bank Investment Management, the Thor wind farm is expected to begin operations in 2027. Once operational, it will supply renewable electricity to more than one million Danish households.
The substation will serve as the central hub for collecting and exporting power generated by the wind turbines, which will be installed in the North Sea off the west coast of Jutland.
The Thor project forms part of Denmark’s broader strategy to expand offshore wind capacity and meet long-term decarbonisation targets.
