Ørsted Wind Power and Jan De Nul Group have signed 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, a milestone for the company according to Peter De Pooter, manager offshore renewables at Jan De Nul Group.

“It will be the maiden project for our new NextGen Heavy Lift Vessel Les Alizés,” he said. “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,” he added.

The 242 MW Gode Wind 3 and 900 MW Borkum Riffgrund 3 Wind Farms are owned and developed by the Danish renewable energy company Ørsted Wind Power. Both wind farms will use 11 MW Siemens Gamesa turbines and are located in the German North Sea.

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.
