Offshore Windmill Installation Vessel

Installation of first telescopic leg crane:


Last week, the boom for the first offshore telescopic leg crane has successfully been installed onto the slewing platform onboard the SC-14000XL at Japan Marine United Corporation.The 2500t offshore heavy lift crane is designed, manufactured and commissioned by the heavy lift group of NOV’s subsidiary GustoMSC and installed on the SC-14000XL, Shimizu’s wind installation jack-up vessel. The GustoMSC designed vessel will be the largest self-elevating platform for offshore wind installation in Japan and capable of installing next generation wind turbines.

VOLTAIRE BEING EQUIPPED WITH CRANE AND LEGS:


One meter higher than the Eiffel Tower. That’s how high Jan de Nul’s 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. 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 3,000 tonnes, a giant that has just been installed on board at the shipyard in China.
With a crane house weighing 1800 tonnes, a boom length of 140 metres and weighing 800 tonnes, 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. We are now gradually increasing the height until they reach their full 131.5 metres.

With both feet in the middle of the energy transition
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!
