Jan De Nul’s next generation heavy-lift vessel Les Alizés has left the CMHI Haimen Shipyard in China and is currently on its way to Europe. The vessel was delivered by the shipyard on 16 January and departed on 19 January.
Les Alizés is specifically designed for loading, transporting, lifting and installing offshore wind turbine foundations. The main features are a main crane of 5000 tonnes, a deck loading capacity of 61,000 tonnes and a deck space of 9300 m2.
With these characteristics, the vessel can easily transport the heavier future foundations, several in one trip, to the offshore installation site, with direct benefits in planning, fuel consumption and emissions reduction.
Jan De Nul’s Les Alizés and its new jack-up installation vessel Voltaire are the first seaworthy installation vessels in the world with extremely low emissions (Ultra-Low Emission Vessel or ULEv for short). Both are equipped with an exhaust gas filtering technology that complies with the strict European Stage V. The highly advanced dual exhaust filter system removes up to 99 per cent of nanoparticles from emissions using a diesel particulate filter (DPF) followed by selective catalytic reduction system (SCR) for NOx removal.

Floating installation
Les Alizés is a crane vessel for floating installation, which means that it is not dependent on water depths and seabed conditions. As such, it will be able to install heavier and larger foundations into deeper waters and in more challenging seabed conditions.
Les Alizés’ maiden voyage takes it to Europe for its first mission in Germany: the transport and installation of 107 monopile foundations and one offshore substation topside at Ørsted’s Gode Wind 3 and Borkum Riffgrund 3 offshore wind farm.
Jan De Nul had ordered the vessel in November 2019.
