Huisman has received an order to deliver a Travelling Load Stabilising System, which will be integrated into both 3,000+mt Leg Encircling Cranes for Havfram’s two new NG-20000X-HF Wind Turbine Installation Vessels. This system enables Havfram to stabilise wind turbine components during installation, particularly blades, but also nacelles and tower segments.
The system consists of two pairs of tuggers working together to control the position of the load. One pair is fitted on independent trolleys that can travel along an integrated rail along the crane’s stiff boom. The rigid connection between the rail and the crane boom enhances overall stability.
The trolleys automatically follow the main block to maintain an optimal tugger line configuration. The second pair of tugger lines is deployed from the crane tip, providing a force perpendicular to the first pair. By approaching the load from two directions, the system offers significantly more control than a conventional single pair of tuggers.
The Travelling Load Stabilising System will function as an integral part of the cranes and will be operated from the crane cabins, with an optional walk-around box (WAB). The Leg Encircling Cranes and Auxiliary Crane packages are currently under construction at Huisman’s production facility in Zhangzhou, China. Upon completion, they will be delivered to Yantai CIMC Raffles Offshore, where they will be installed on the NG-20000X-HF Wind Turbine Installation Vessels being built for Havfram.
