CAPELLEN, Luxembourg  Jan De Nul Group's floating heavy-lift vessel Les Alizés left the CMHI Haimen Shipyard in China on Jan. 16 and is heading for Europe.

Les Alizés is specifically designed for loading, transporting, lifting and installing offshore wind turbine foundations. The vessel features a crane of 5,000 tons, a deck loading capacity of 61,000 tons and a deck space of 9,300 sq m.

"Her dimensions and lifting capacity make her perfectly fitted to transport several of today's heavy wind turbine foundations in one trip," the company stated.

Les Alizés will perform its first mission in Germany. There, the vessel will transport and install 107 monopile foundations and one offshore substation topside for Ørsted’s Gode Wind 3 and Borkum Riffgrund 3 offshore wind farms.

In May 2022, it was announced that Smulders would supply the secondary steel elements for the two wind farms offshore northern Germany. The components are for the 23 TP-less foundations and single offshore substation foundation for Gode Wind 3, and the 83 TP-less foundations for Borkum Riffgrund 3. Smulders also was scheduled to supply boat landings, external ladders, suspended internal cages (SIP-units) and anode cages.

In late 2021, Ørsted contracted Cadeler A/S to transport and install wind turbine generators and also contracted Boskalis to install the inter-array cables for the Gode Wind 3 and Borkum Riffgrund 3 projects in the German North Sea.
