Jan De Nul kicks off the development of its 5,000 tonnes crane vessel Les Alizés. The metal chopping ceremony befell on the shipyard China Merchants Heavy Industry (Jiangsu) Co., Ltd. in China, within the presence of Jan De Nul representatives, the Vice General Manager of the shipyard and the Country Chief Executive of M&O China of Bureau Veritas.
After 13 months of preparation, designing and planning, the undertaking groups of each the Shipyard and Jan De Nul Group are glad to succeed in this primary necessary milestone.
Les Alizés will primarily be used for the development of offshore wind farms, however along with her highly effective crane, she can be extraordinarily appropriate for decommissioning offshore oil and gasoline platforms. Thanks to her dimensions and spectacular lifting and loading capacities, Les Alizés will have the ability to load out, transport and set up a number of models of the most important and heaviest wind turbine foundations. In addition, as a crane vessel that floats, it is going to be in a position to set up heavier and bigger foundations into deeper waters and in tougher seabed situations.
Les Alizés is particularly designed for loading, transporting, lifting and putting in offshore wind turbine foundations. The principal options are a principal crane of 5,000 tons, a deck loading capability of 61,000 tons and a deck area of 9,300 m². With these traits, Les Alizés can simply transport the heavier future foundations, a number of in a single journey, to the offshore set up web site, with direct advantages in planning, gas consumption and emissions discount.
Unlike Jan De Nul’s different offshore set up vessel beneath building Voltaire, Les Alizés doesn’t have 4 legs to raise itself above the ocean floor. It is a crane vessel for floating set up, which signifies that the vessel will not be depending on the water depths and the seabed situations. Les Alizés is supplied with a high-performance DP2 system.
Les Alizés might be geared up with an exhaust gasoline filtering expertise that complies with the strict European EURO STAGE V tips for emissions on land and inland waterways. This extremely superior twin exhaust filter system removes as much as 99% of nanoparticles from emissions utilizing a diesel particulate filter (DPF) adopted by selective catalytic discount system (SCR) for NOx removing.
Additionally, the crane vessel might be fitted with an Energy Storage System (ESS), forming a hybrid setup along with the primary diesel engines. This ESS will compensate energy peaks on the primary engines and recuperate vitality from the heavy raise crane, leading to optimised engine operation and fewer gas consumption and emissions.
And lastly, Les Alizés can 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 different residual waste. The second Green Passport label signifies that all supplies and dangerous substances are mapped out throughout the building section, so as to facilitate the recycling of the vessel when decommissioned. Both certificates are issued by a specialised exterior company.
