Les Alizés is specifically designed for loading, transporting, lifting, and installing offshore wind turbine foundations.

Currently under construction at the CMHI Haimen shipyard in China, Les Alizés will be capable of building the newest generation of offshore wind farms once delivered in April 2022, Jan De Nul said.

The vessel’s main features are a main crane of 5,000 tons, a deck loading capacity of 61,000 tons, and a deck space of 9,300 square metres.

”Adding some of our new Red Rock technology features to this crane package delivery, we’re proud to be partnering with Jan De Nul Group on offering the most efficient installation method of offshore wind farms. This is a clear indication that Red Rock is on the fast-track to literally becoming a heavyweight contributor to the offshore wind market,” said Red Rock CCO Thomas Holte.

Les Alizés will be able to load out, transport, and install multiple units of the largest and heaviest wind turbine foundations, Jan De Nul said.

In addition, as a crane vessel that floats, it will be able to install heavier and larger foundations into deeper waters and in more challenging seabed conditions.

”Sitting on giant foundations up to 2,500 tons, stretching 270 meters towards the sky, and with blades the length of football fields, it is satisfactory that Red Rock technology is needed to add value to an undertaking we all consider to be a tall order, which is to ensure the vessel’s capability to install very large wind turbines greener and less expensive,” said Holte.
