Legs and Crane Being Installed on Jan De Nul’s Voltaire

One meter higher than the Eiffel Tower. That’s how high Jan De Nul’s brand new offshore jack-up installation vessel Voltaire will be able to reach. And that’s necessary: the vessel is designed to install the offshore wind turbines of the future, with turbines over 270m high and blades 120m long. Size matters!
The Voltaire is specifically designed to transport, hoist and install offshore wind turbines, transition pieces and foundations.

For these lifting works, the vessel is equipped with a main crane of more than 3,000t, a giant that has just been installed on board at the shipyard in China.

With a crane house weighing 1800t, a boom length of 140m and weighing 800t, this is the largest Leg Encircling Crane ever built. The crane will use a Universal Quick Connector (UQC) to pick loads quickly and completely without manual handling, i.e. fully automated. A big step forward in safer working!

The legs enabling the Voltaire to lift itself above the water surface, are also being mounted on board. The first part of the legs were installed just before the launching at the end of January. They are now gradually increasing the height until they reach their full 131.5m.

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!
