Yesterday (29 April 2021), at the CMHI Haimen shipyard in China, the keel laying ceremony was held for Jan De Nul Group's Heavy Lift Crane Vessel Les Alizés took place.

Les Alizés will be equipped with a main crane of 5,000 tons, a deck loading capacity of 61,000 tons and a deck space of 9,300 m².  The vessel is designed to transport and install multiple units of the largest and heaviest wind turbine foundations in one trip. It is expected to be ready for operations in 2022.

The Ultra-Low Emission vessel will be equipped with an exhaust gas filtering technology that complies with the EURO STAGE V guidelines for emissions on land and inland waterways, and will also have a Cleanship NDO7 label and a Green Passport EU label.


Les Alizés will be equipped with several green measures and innovations to minimize the environmental impact, such as a highly advanced dual exhaust filter system that is said to be able to remove up to 99% of nanoparticles from emissions using a diesel particulate filter (DPF) followed by selective catalytic reduction system (SCR); as well as an onboard Energy Storage System optimising engine operation and reducing fuel consumption and emissions. The vessel will also have a Cleanship NDO7 and a Green Passport EU label.

The Cleanship label confirms that the vessel checks and minimizes the waste water and all other residual waste. The second Green Passport label means that all materials and hazardous substances are mapped out during the construction phase, in order to facilitate the recycling of the vessel when decommissioned. Both certificates are issued by a specialized external agency.

In addition to
Les Alizés , Jan De Nul is awaiting the completion of the construction of its new offshore jack-up installation vessel Voltaire at Cosco Shipping Shipyard in Nantong, China. Voltaire is specifically designed to transport, lift and install offshore wind turbines, transition pieces and foundations for current and future developments. Jan De Nul claims that the vessel will have better operational limits compared to the existing jack-up installation vessels. She will be delivered in 2022.
