Huisman has confirmed that it will supply the crane for Cadeler’s new F-class installation vessel
The Dutch company has been awarded a contract by COSCO Shipping (Qidong) Offshore Co Ltd, the shipyard building the vessel, for the design and construction of a leg tower crane.
The contract follows contracts awarded in 2021 for two identical 2,600-tonne leg-circling cranes for Cadeler’s X-class vessels.
Using the crane, Cadeler will be able to install foundations and wind turbines. Class F vessels are a unique design that can be converted from a foundation installation unit to a wind turbine installation vessel in a short time.
Huisman’s scope of work includes the design, engineering and construction of the crane at its production facility in Zhangzhou, China. The cranes will be commissioned in 2025 at COSCO’s shipyard in Qidong, China, where the F-class vessel will be built.
The crane surrounding the legs is fully electric, resulting in high positioning accuracy, low maintenance and high reliability. It is designed for reduced energy consumption. It will have an in-house developed slewing bearing system, providing reliable and accurate positioning.
The boom design makes it stiffer and lighter than a conventional design. The fact that the boom is of rigid construction will lead to reduced movement at the end of the crane. A small rear swing allows optimized use of the free space on the deck.
