To be used for the installation of offshore wind turbine monopile foundations, it will feature a fully revolving 5,tonne crane and the Ulstein U-stern. With a U-shaped notch at the stern, the HLV is designed to upend a monopile being stored lengthwise on the vessel using the 5,tonne crane and an upending system with a gripper that enables installation directly at the notch.
Completion is scheduled for May , with operation anticipated in the fall of Huisman says Its 5, tonne active heave-compensated tub mounted crane features a dual main hoist and universal quick connector, enabling efficient, safe tool changes to reduce cycle time and safety risks.
Key advantages of the low weight tub mounted crane include a compact tail swing for deck space optimization, no counterweight, full revolving capacity, and an in-house produced slew bearing. With the monopiles being stored lengthwise on the vessel, the integrated upending system enables direct handling from storage to installation. Ulstein says that the award of its contract follows feasibility and concept studies in based on its HX with the U-stern. The vessel will also feature the X-bow, and at meters long and 56 meters wide, will be the largest X-bow vessel yet built.
