Half of the monopile foundations are now in place at the Thor offshore wind farm site, as Jan De Nul’s heavy-lift vessel Les Alizés installed the 36th of the project’s total 72 monopiles on 15 July.
“With Thor we are constructing Denmark’s largest offshore wind farm to date. Reaching halfway in the safe installation of the monopiles is a great achievement. My thanks go to all colleagues and partners involved for their contribution. Building a project of this size and scale is a great opportunity to demonstrate our expertise in delivering valuable offshore wind farms around the globe” , said Sven Utermöhlen , CEO of RWE Offshore Wind.
Once complete in 2027, the 1.1 GW Thor will become Denmark’s largest offshore wind farm and is expected to produce enough renewable energy to supply the equivalent of more than one million Danish households.
The first monopile was installed at the project site in the Danish North Sea, located approximately 22 kilometres off the west coast of Jutland, in April this year.

The monopiles are shipped from the heavy-lift terminal in Eemshaven, the Netherlands, to the Thor site, with five monopiles loaded in one shipment. The secondary steel structures, which include boat landings and internal and external platforms for the foundations, are being transported from the Danish Port of Thyborøn, which is the offshore construction base for Thor.
The 72 monopiles, measuring around 100 metres in length and weighing up to 1,500 tonnes each, and the secondary steel structures are being delivered by Dajin Offshore and EEW SPC .
