All 72 wind turbine foundations at the Danish Thor offshore wind site, developed by RWE, are now equipped with secondary steel and ready for the wind turbine installation, which is expected to start in the spring of 2026.
The installation of the secondary steel structures, including boat landings, main access platforms, and internal cassettes, was completed at the beginning of November, less than six months after Van Oord’s offshore wind installation vessel MPI Adventure started the work, operating from the Danish Port of Thyborøn.
To protect the foundations from the harsh conditions at sea until the turbine towers are mounted, reusable hard covers have been installed, RWE said on 11 November.
Thor’s monopiles, delivered by Dajin Offshore and EEW SPC, were installed by Jan De Nul using its heavy-lift vessel Les Alizés , which put the final monopile in place in September.
