Royal IHC offers a sophisticated range of cable lay vessels covering a wide range of power cable types from inter-array, export, interconnector and any combination.




Cable lay equipment

We offer a full range of cable lay equipment to suit your needs and are equally experienced supplying full cable lay spreads or integrating a specific part into a pre-existing spread. You can also rent equipment for these purposes. 

Our carousels can be installed above or below deck and range in size from small 100t auxiliary tanks to large laying baskets up to 7000t and beyond.

A cornerstone of our efficient cable lay spreads is our quadrant handling system which provides several benefits to operational efficiency, cable safety and ease of use of the system overall.

  • operational efficiency is maximised by minimising the duration of the quadrant handling operation
  • cable safety is maximised by reducing cable bending to a minimum while overboarding the quadrant and cable, maintaining a tangent to the stern chute
  • ease of use of the lay system is maximised when paired with our “O-Loop” systems, as the quadrant can be engaged during normal lay operations to decouple the carousel and the tensioner, making it easier for the operator to speed match.

We can provide all other equipment required for safe, efficient cable lay such as active heave compensated winchestensioners with breakback functionality to allow easy passing of the quadrant, route paths, loader arms, stern chutes, whiskers, transpooling equipment  and spare cable storage.

Cable burial

Royal IHC is at the forefront of cable burial/subsea plough technology striving to safely and efficiently bury power cables despite ever changing cable parameters, deeper burial depths and deeper water depth. Our launch and recovery systems (LARS) can handle a range of products from high bollard pull ploughs, to tethered trenchers and ROVs and are suitable for our own vehicles and others.
