Next-Gen installation vessel Les Alizés kicks off maiden assignment

The vessel which was delivered early 2023 arrived in the Dutch harbour Eemshaven at the end of June, where the first monopiles were loaded before departing to the installation location in the German North Sea, Jan De Nul said.

In total Les Alizés will transport and install 106 wind turbine monopile foundations and one offshore substation foundation, including associated topside for the German offshore wind farms Gode Wind 3 (253 MW) and Borkum Riffgrund 3 (913 MW), developed by Danish company Ørsted.

Both wind farms will use 11 MW Siemens Gamesa turbines and monopiles without transition pieces. Before installation, scour protection will be installed at all 107 locations. Once completed, these wind farms will generate enough electricity to power approx. 1.2 million German households every year.

Jörg Kubitza, Managing Director for Ørsted in Germany: "With the installation of the foundations for our two new projects this year, we are laying the ground work for additional, large-scale renewable energy at sea. And thus further establish offshore wind power as a pillar of the energy transition. I am pleased that we have now reached the next milestone. In addition to the required capacities that will have to be installed in the coming decades, our projects also exemplify how offshore wind power can be built out in a value-creating and competitive manner in Germany – if the right framework conditions are in place."

Peter De Pooter, Manager Offshore Renewables at Jan De Nul Group: “This contract is an important milestone for us, as it is the maiden project for our new Next-Gen heavy lift vessel Les Alizés. We are looking forward to install and complete both wind farms in close collaboration with our client Ørsted. Together with Voltaire’s first mission and other projects, we are proud to contribute to construct the global transition to renewable energy by installing these offshore wind turbines in the most efficient and environmentally friendly way possible.”
