Inter-array cable laying vessels

The inter-turbine (array) cable laying vessels are operating in-field at the offshore wind farms, laying power cable between the wind turbines. The cables are typically installed in single lengths from one turbine to the next. In general, wind turbines are increasing, which means that the cable size is also increasing.

Elevating cable laying operations

The SX127 is a compact and versatile design, optimised for in-field cable laying operations. The vessel is prepared for operations with a power cable, including two underdeck carousels. With a high deadweight capacity of 7,200 tonnes, the vessel can carry a cable weight of 6,000 tonnes.

Due to a growing demand for higher cable capacity, the current trend is towards even larger vessels. The SX238 is a flexible platform designed for inter-array operations, reaching a perfect compromise between vessel size and cable capacity. The vessel has two under-deck carousels, enabling up to 6,000 t cable capacities, and the platform has a tailor-made cable protection system (CPS) module for effective mobilisation and installation.
