Jan De Nul launches the Voltaire, the world’s largest next-generation jack-up vessel

Just twenty days after Les Alizés, Jan De Nul Group launched the Voltaire, a next-generation offshore jack-up rig vessel for offshore renewable energy and decommissioning, at the COSCO Shipping shipyard in Nantong, China, according to the press release. the society. This vessel will be the second and largest jack-up vessel in Jan De Nul’s fleet and will be able to support the renewable energy industry to build next-generation offshore wind farms. Like Les Alizés, the Voltaire is due for delivery in the second half of 2022 and will be welcomed by a global offshore wind industry that is already forecasting shortages of installation vessels by mid-decade.

Designed in-house and pushing the boundaries of engineering, Voltaire is designed 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 it to build current and future generation offshore wind farms. Voltaire is ready for the future of offshore renewables and will also be available for the oil and gas industry for the dismantling of offshore structures.

The Voltaire is a jack-up vessel equipped with a high-tech lifting system. Four giant 130 meter legs support the vessel to achieve stable working conditions at unrivaled water depths of up to 80 meters and with a high load of 16,000 tons.

With the growing demand for decarbonization and green electricity at lower cost, offshore wind turbine and foundation components continue to rapidly increase in size to a point where their dimensions have greatly exceeded the current installation capacity of the market.

Jan De Nul Group has prepared for the arrival of next-generation offshore wind components and announced in 2019 the order of the Voltaire, the tallest and most advanced jack-up installation vessel in the world, and the Alizés, a equally revolutionary floating installation vessel.

With unrivaled lifting capacities of over 3,000 tonnes and 5,000 tonnes respectively, as well as Jan De Nul’s existing submarine cable laying trio, these vessels will have the capacity to install all wind power requirements. new generation offshore. Today it is clearer than ever that Jan De Nul made the right decision by ordering the Voltaire and Les Alizés in 2019.

The Voltaire’s success was evident in 2020 with the award of its first mission just one year after its order: it will be mobilized in the United Kingdom for the construction of the 3.6 GW Dogger Bank offshore wind farm, the largest offshore wind farm in the world, transporting and installing a total of 277 GE Haliade-X turbines up to 14 MW. Thus, the Voltaire will contribute to the largest offshore wind farm in the world, generating enough energy to power up to 6 million homes each year, around 5% of the UK’s electricity needs.

The highly innovative main crane will be fitted with a Universal Quick Connector (UQC), developed by Huisman, and leveraging the expertise of Jan De Nul’s operational and engineering teams. The result is an innovative and revolutionary UQC, which will bring a major change in safer offshore lifting activities.

Compared to Jan De Nul’s other Jack-Up Vessel Vole au vent, this new ship has almost double the deck space. Not only is this vessel capable of loading the next generation of wind turbines and foundations, but the larger deck space will also allow Jan De Nul to optimize offshore installations and reduce fuel consumption and emissions. In addition, the Voltaire will be able to run on second-generation biodiesel, which reduces the fuel’s carbon footprint by up to 90%.

In common with Les Alizés, the Voltaire features a highly advanced twin exhaust filter system, removing up to 99% of nanoparticles from emissions using a diesel particulate filter (DPF) and reducing emissions of NOx and other pollutants by means of a selective catalyst. reduction system (SCR) to levels that comply with EU Stage V regulations. Together, these vessels will be the world’s first two seaworthy installation vessels with an extremely low carbon footprint.
