The first monopile for the Thor offshore wind farm in Denmark has been completed at Dajin Offshore Heavy Industry’s Penglai facility in China.
In April last year, RWE selected Dajin Offshore and EEW SPC to deliver 36 monopiles each, together with secondary structures, for the Thor offshore wind farm.
A few months later, the Chinese manufacturer signed deals for internal platforms to be delivered by Wulkan Shipyard from Szczecin, Poland, electrical outfitting including installation from ProCon Wind Energy headquartered in Aalborg, Denmark, and concrete external working platforms from the Polish subsidiary of Per Aarsleff, Denmark.
In China, the cutting of the first steel for monopiles, which do not need transition pieces, began at the start of 2024.
The foundations, designed by Wood Thilsted, will be installed by Jan De Nul Group, who will provide the vessel for the work that is expected to be carried out next year.
The TP-less monopiles will support Siemens Gamesa’s SG 14-236 DD wind turbines . Siemens Gamesa will manufacture recyclable rotor blades for 40 of the 72 wind turbines.
Installation of the units at the site located approximately 22 kilometres from Thorsminde on the west coast of Jutland is expected to start in 2026.
With a planned capacity of more than 1,000 MW, Thor is Denmark’s largest offshore wind farm to date.
Once fully operational, which is planned no later than the end of 2027, the wind farm will be capable of producing enough green electricity to supply the equivalent of more than a million households, or one in three Danish households, according to RWE.
