Luxembourg-based marine services company Jan De Nul has ordered a second next-generation offshore wind turbine installation vessel.

The new vessel, named Les Alizés, will be built at China Merchants Industry Holdings shipyard in in Haimen, China with delivery in 2022.

The order comes just six months after Jan De Nul pulled the trigged on the 3,000-ton capacity jack-up offshore installation vessel Voltaire, which is also due for delivery in 2022.

Unlike the Voltaire, the Les Alizés will be a floating installation crane vessel with an impressive lifting capacity of 5,000 tons.

Both vessels are designed for building the newest generation of offshore wind farms, but will also be equipped for decommissioning offshore oil and gas platforms.

“We continue to invest in the future of offshore renewable energy. By ordering Les Alizés today, from 2022 we will have not one, but two, offshore installation vessels that will be able to install the newest generation of offshore wind farms,” said Philippe Hutse, Offshore Director at Jan De Nul Group. “This is how we offer our customers the most efficient installation method. Similar to the Voltaire, we have financed this investment by means of a green loan thanks to the green emissions reduction technology on board the vessel. During the design phase, as is the case for all our new vessels, we studied very carefully the environmental impact and the solutions to minimize that impact.”

Les Alizés will be specifically designed for loading, transporting, lifting and installing offshore wind turbine foundations. The 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 m². Unlike the Voltaire, Les Alizés will not have four jack-up legs, rather it will be equipped with a high-performance DP2 system. It will also be to be an Ultra-Low Emission Vessel with advanced environmentally-friendly systems such as an advanced dual exhaust filter system that will remove 99% of nanoparticles from emissions.
