Netherlands-based ThreeX BV has signed a letter of award with Chinese yard CIMC Raffles for building a heavy-lift vessel for offshore wind farm installation work.

The vessel will accommodate a 7500-tonne crane, capable of installing giant next-generation offshore wind turbines, foundations and transformer platforms.

The unique twin-hull vessel design has been developed by Vuyk Engineering Rotterdam, a subsidiary of Royal IHC Group, and is aimed at lowering transport and installation costs for future wind farm developments.

The HLV7500 vessel, measuring 198 metres by 82 metres, will be equipped to lift structures to a height above sea level of 178 metres for the auxiliary hoist and 160 metres for the main hoist.

It will be among the largest of its kind in the industry, with a capacity to transport and install the largest structures and components.

The heavy-lift crane vessel combines a large deck space with industry-leading lifting capacity and speed, according to ThreeX BV.

Kongsberg Maritime will supply an integrated package that includes engines and thrusters including all engineering.

ThreeX BV added that it has been in dialogue with several offshore wind developers and contractors for offshore wind projects in Europe, Asia and the US.
