Installation Vessel Les Alizes Embarks on Maiden Assignment


Les Alizés, Jan De Nul Group‘s newest crane vessel, has reported for her inaugural assignment: installing the first of 107 monopile foundations for the construction of Orsted’s Gode Wind 3 and Borkum Riffgrund 3 offshore wind farms in Germany.

The first monopiles were loaded on Les Alizés at the Dutch Eemshaven seaport at the end of June. The vessel then departed to the installation location in the German North Sea.

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

Both wind farms will use 11 MW Siemens Gamesa turbines. Orsted will use monopiles without a transition piece. Before installation, scour protection will be installed at all 107 locations.

Peter De Pooter, manager offshore renewables at Jan De Nul Group, notes: “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.”
