Luxembourg-based Jan De Nul Group has been awarded a contract to transport and install monopolies for two offshore wind projects in Germany under development by Danish renewable energy company Ørsted Wind Power.

The 242 megawatt (MW) Gode Wind 3 and 900 MW Borkum Riffgrund 3 wind farms are located in the German North Sea.

Jan De Nul will utilize its next generation offshore installation vessel Les Alizés to transport and install 107 monopile foundations and one offshore substation, including the associated topside. Scour protection will also be installed at all monopile locations prior to installation.

The project will mark the first assignment for the Les Alizés and the transport and installation will start in 2023.

Both wind farms will use 11-MW Siemens Gamesa turbines.

The Borkum Riffgrund 3 will be located adjacent to Ørsted’s existing offshore wind farms Borkum Riffgrund 1 and Borkum Riffgrund 2, while Gode Wind 3 will be close to Ørsted’s Gode Wind 1 and 2.

The projects are still subject to a final investment decision from Ørsted, but completion is currently anticipated in 2024. Once completed, these wind farms will generate enough electricity to power approx. 1.2 million German households every year.

“This contract is an important milestone for us, it will be the maiden project for our new NextGen Heavy Lift Vessel Les Alizés,” said Peter De Pooter, Manager Offshore Renewables at Jan De Nul Group. “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.”

Les Alizés is currently under construction and is planned to be delivered in 2022. The vessel will primarily be used for the construction of offshore wind farms, but her large crane also makes her suitable for decommissioning offshore oil and gas platforms.
