Offshore jack-up installation vessel Voltaire

One meter higher than the Eiffel Tower. That’s how high our brand new offshore jack-up installation vessel Voltaire can reach. And that’s necessary: the vessel is designed to install the offshore wind turbines of the future, with turbines over 270 metres high and blades 120 metres long.

The Voltaire is specifically designed to transport, hoist and install offshore wind turbines, transition pieces and foundations. How will the ship manage this? With a main crane of more than 3,000 tonnes, an operational depth of 80 metres, a payload of approximately 14,000 tonnes and accommodation for more than 100 people.


With these unprecedented dimensions and possibilities, the Voltaire is an important asset for the future of the renewable energy sector. That future revolves more and more around a global energy transition and a minimal impact on the climate. That is why Jan De Nul is equipping its new generation vessels with a double exhaust gas filter system that removes up to 99% of nanoparticles from emissions. An Ultra-Low Emission vessel, in other words!
