Ørsted Wind Power S/A and Jan De Nul Group announced the signing of the final contract for the transport and installation of 107 monopile foundations and one offshore substation topside at Gode Wind 3 and Borkum Riffgrund 3 offshore wind farm. The transport and installation will start in 2023 and will be the first assignment for Les Alizés , the next generation offshore installation vessel of Jan De Nul Group.

Jan De Nul’s scope includes the transport and installation of 106 wind turbine monopile foundations and one offshore substation foundation, including associated topside. For the first time, Ørsted will be using monopiles without the need of installing a transition piece for connecting turbine and foundation. Before installation, scour protection will be installed at all 107 monopiles locations.

Both wind farms will use 11-MW Siemens Gamesa turbines and are located in the German North Sea. The
Borkum Riffgrund 3 more particularly will be located adjacent to Ørsted's existing offshore wind farms Borkum Riffgrund 1 and Borkum Riffgrund 2. Gode Wind 3 will be close to Ørsted's Gode Wind 1&2.

Delivery is expected to be complete in 2024. Once completed, these wind farms will generate enough electricity to power approx. 1.2 million German households every year. The projects are subject to Ørsted’s final investment decision.

Peter De Pooter, Manager Offshore Renewables at Jan De Nul Group, said: “This contract is an important milestone for us, it will be the maiden project for our new NextGen Heavy Lift Vessel Les Alizés. We are most pleased having signed this contract with industry leader Ørsted Wind Power A/S and are looking forward to jointly develop both wind farms. Together with other projects in preparation by Jan De Nul, we are proud to contribute to the global transition to renewable energy by installing foundations and wind turbines in the most efficient way using the best environmentally friendly technologies.”
