LUXEMBOURG – Jan De Nul Group has contracted the CMHI Haimen shipyard in China to build a floating installation crane vessel.
The Les Alizés is 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 sq m (100,104 sq ft).
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, the company said.
The DP-2 vessel is expected to be delivered in 2022.
Jan De Nul has commissioned Huisman to supply the 5,000-metric ton tub mounted crane. It is designed to allow operations with both main hoist and auxiliary hoist in extreme weather conditions and the crane is outfitted with Huisman’s Dual Main Hoist System for easy upending of large structures.
The vessel will also feature a dual exhaust filter system that removes up to 99% of nanoparticles from emissions using a diesel particulate filter followed by selective catalytic reduction system for NOx removal.
According to Jan De Nul, it will be an ultra-low emission vessel (ULEv) and with EURO STAGE V certification (ULEv notation).
The Les Alizés will also have a Cleanship NDO7 label 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 decommissioning.
The vessel is named after the French word ‘alizé’, which means ‘trade wind’.
