Wind Energy – T&I
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.
The Voltaire is being built at the COSCO Shipping Shipyard in Nantong, China.
The 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.
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.
Philippe Hutse, Director Offshore Division at Jan De Nul Group: “The Voltaire will enable us to work in deeper waters and reach ever-higher nacelle heights than before. Adding Voltaire and Les Alizés to the fleet gives us the perfect set of vessels to execute the growing number of large and clustered international offshore wind projects. Our forward-looking view on market trends and the quick decision-making to invest in this set of Next Gen installation vessels, have done us no harm. The Voltaire and Les Alizés have all the required specifications to meet the upcoming challenges in offshore renewables. We are proud to be recognised for the choices we made back in 2019, and look forward to continuing our journey, alongside industry leaders, through our contribution to renewable energy growth in the worldwide energy transition.”
The success of the Voltaire was demonstrated in 2020 with the award of her first assignment only one year after her order: she will mobilize to the United Kingdom for the construction of the 3.6 GW Dogger Bank offshore wind farm, the world’s largest offshore wind farm, transporting and installing in total 277 GE Haliade-X turbines up to 14MW.
