Jan De Nul orders second next generation offshore installation vessel Les Alizés
Just six months after the investment announcement for the offshore installation vessel Voltaire, Jan De Nul Group orders Les Alizés, a floating installation crane vessel from the CMHI Haimen shipyard in China, the company said in its release.
Together with the Voltaire, this new vessel will be in a super-size class of its own, capable of building the newest generation of offshore wind farms. Les Alizés, that will be ready in 2022, is equipped with a crane having a lifting capacity of 5,000 tons and equally impressive lifting heights.
Les Alizés will mainly be used for the construction of offshore wind farms, but with her impressive crane she is also extremely suitable for decommissioning offshore oil and gas platforms.
Thanks to her dimensions and impressive lifting and loading capacities, Les Alizés will be able to load out, transport and install multiple units of the largest and heaviest wind turbine foundations. 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 vessel will be built at a shipyard of China Merchants Industry Holdings Co. Ltd., located in Haimen, Nantong City, China. As a subsidiary of China Merchants Group, this shipyard has a proven track record in supplying marine and offshore facilities which gives Jan De Nul Group sufficient confidence to award this contract to CMIH.
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 m². With these characteristics, Les Alizés 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.
Unlike the Voltaire, Les Alizés does not have four legs to lift itself above the sea surface. It is a crane vessel for floating installation, which means that the vessel is not dependent on the water depths and the seabed conditions. Les Alizés is equipped with a high-performance DP2 system.
The highly advanced dual exhaust filter system removes up to 99% of nanoparticles from emissions using a diesel particulate filter (DPF) followed by selective catalytic reduction system (SCR) for NOx removal.
As a result of these exhaust filtering systems, Les Alizés and the Voltaire will be the first seaworthy installation vessels in the world with extremely low emissions (Ultra-Low Emission Vessel or ULEv for short) and with EURO STAGE V certification (ULEv notation).
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. Both certificates are issued by a specialized external agency.
On 5 July 2019, Jan De Nul Group concluded an agreement for a green loan with a consortium of five banks, led by KBC Bank, for the financing of both investments. The consortium of five banks consists of KBC Bank, BNP Paribas Fortis, ING Luxembourg, Rabobank and Belfius Bank.
