U.K. engineering company Multisec, in partnership with Durham Lifting, has designed and manufactured one of the largest C-Hooks ever produced for the offshore wind industry.
The bespoke lifting tool, developed for SeAH Wind, has a capacity of 125 tonnes and can handle monopile sections measuring up to 4.2 meters in length and 15.5 meters in diameter. The company said the device will provide a versatile and reliable solution for handling monopile cans and cones.
Unlike traditional C-Hooks, which are limited to single-direction tilt adjustment, Multisec’s design incorporates a dual gantry crane system with motorized counterweights that can travel to either side of the lifting point. The feature enables controlled clockwise and counterclockwise rotation, ensuring safe handling across monopile sections of varying dimensions and centers of gravity.
To improve durability, the mechanical load path was engineered to ensure that primary forces are not transferred through welds, enhancing performance in heavy-duty applications.
“With offshore wind projects continuing to scale, the requirement for safe, adaptable lifting equipment has never been greater. Multisec’s latest innovation reflects its commitment to supporting the energy transition with robust solutions designed to meet the technical demands of modern offshore infrastructure,” said Multisec.
