RWE has installed all 72 monopile foundations at the 1GW Thor offshore wind farm in the Danish North Sea.
The company said the installation was completed over five months using Jan De Nul’s vessel Les Alizés.
Tobias Keitel, chief technology officer at RWE Offshore Wind, said: “Together with our partner, Norges Bank Investment Management, we are well on track with the construction of Thor – Denmark’s largest offshore wind farm to date. The safe installation of the monopiles is testament to the expertise, dedication and collaboration of the entire team involved.”
The monopiles, up to 100 metres long and weighing 1500 tonnes, were shipped from Eemshaven in the Netherlands to the site 22km off Jutland.
Secondary steel structures, including boat landings, will be installed later this year from the Danish Port of Thyboron.
RWE said innovative reusable hard covers will protect the monopiles until towers are mounted next year, reducing waste and supporting circularity.
Turbine installation from the Port of Esbjerg is scheduled to begin in 2026. Thor will be the first offshore project to feature steel towers manufactured with a lower carbon footprint and half the turbines will use recyclable blades.
When operational in 2027, the wind farm will supply the equivalent of more than one million Danish households.
Thor, jointly owned by RWE (51%) and Norges Bank Investment Management (49%), will be operated from a new service base in Thorsminde, creating up to 60 jobs.
