The offshore and onshore maneuvers to bring the two main cables of the Thor offshore wind farm to the Danish mainland have been completed. Thor offshore wind farm. The Belgian company Jan De Nul, specialized in offshore infrastructure, was in charge of this complex operation that marks a key step in the construction of the largest wind farm in Danish waters.
Located 22 kilometers off the North Sea coast, the Thor farm is designed to have an installed capacity of 1,080 megawatts, sufficient to supply renewable electricity more than one million homes. This project is the result of a partnership between RWE (51%) and Norges Bank Investment Management (49%), combining energy expertise and Norwegian public investment.
Specialized technology for cable connection
To lay the cables, Jan De Nul used its Isaac Newton vessel, which specializes in the deployment of submarine cables. On land, the Moonfish machine drilled into the coastal subsoil to facilitate cable entry without affecting the coastal environment. This technique, known as HDD (Horizontal Directional Drilling), minimizes the environmental impact of the process.
Once connected to the national grid, Thor will become a pillar of Denmark’s electricity supply. This step advances the country’s decarbonization and strengthens its leadership in renewable energy in Europe. renewable energies in Europe.

The cabling activities are part of a tight schedule that aims to have the park operational within the next few years. The project not only improves the Danish power infrastructure but also boosts the development of sustainable offshore solutions.
