Just twenty days after Les Alizés, Jan De Nul Group launched the Voltaire, a Next-Gen Offshore Jack-Up Installation Vessel for offshore renewables and decommissioning, at the COSCO Shipping Shipyard in Nantong, China. This vessel will be the second and largest jack-up vessel in Jan De Nul’s fleet, and able to support the renewable energy industry to build next generation offshore wind farms. In common with Les Alizés, the Voltaire is due for delivery in H2 2022, and will be welcomed by a global offshore wind industry that is already forecasting installation vessel shortages by mid-decade.Designed in-house, and pushing engineering boundaries, Voltaire is built to transport, lift and install offshore wind turbines, transition pieces and foundations. The main crane with a capacity of over 3,000 tonnes will enable her to construct the current and future generation of wind farms at sea. Voltaire is ready for the future of offshore renewables, and will also be available to the oil and gas industry for the decommissioning of offshore structures. The Voltaire is a jack-up vessel fitted with a high-tech jacking system. Four giant legs of 130 metres support the vessel to achieve stable working conditions at unsurpassed water depths up to 80 meters and with an elevated load of 16,000 tonnes. With the increasing demand for decarbonisation and lower-cost green electricity, offshore wind turbine and foundation components continue to rapidly increase in size to a point where their dimensions have largely outgrown the current market installation capability. Jan De Nul Group has been preparing for the arrival of next generation offshore wind components and in 2019, announced the order of the Voltaire, the world’s tallest and highly advanced jack-up installation vessel, and Les Alizés, an equally revolutionary floating installation vessel. With unrivalled lifting capacities of over 3,000 tonnes and 5,000 tonnes respectively, along with Jan De Nul’s existing subsea cable laying trio, these vessels will have the capability to install the complete requirements of next generation offshore wind. Today, it is clearer than ever that Jan De Nul made the right decision by ordering the Voltaire and Les Alizés in 2019.
