SCHIEDAM, the Netherlands — COSCO Shipping (Qidong) Offshore has commissioned Huisman to design and construct a leg encircling crane (LEC) for the new Cadeler F-class jackup offshore wind vessel.
It follows contracts last year for two identical 2,600-metric ton LECs for Cadeler’s X-class vessels.
With the new crane, Cadeler will be capable of installing foundations and wind turbines for next-generation offshore wind projects. The F-class design allows the vessel to be converted from a foundation installation unit to a wind turbine generator installation vessel within a short period.
Huisman’s work scope comprises design, engineering and construction of the LEC 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.
According to Huisman, features of the LEC design include a fully electrically driven system, which leads to high positioning accuracy, reduced maintenance and a high level of reliability; an optimized energy grid, which reduces the crane’s energy consumption; in-house developed slew bearing system, providing accurate positioning of the crane; boom designed to be stiff and lighter in weight, with reduced motion at the crane tip; and a small tail swing allowing for better use of free deck space.
