Fiber optic cable lay vessels

Submarine telecom cables are connecting the world by transferring data. Huge lengths of fiber optic cables are connecting countries and even continents with each other. The telecom cables and repeaters are delicate products and installing long lengths of these cables at great depths require the right asset.

Sovereign vessel

Built for telecom projects

Royal IHC’s CLV T6000-23 is an excellent example of a vessel built for a specialist, telecom cablelay project. The vessel was designed drawing on Royal IHC’s knowledge of cable installation and burial operations, in combination with extensive design skills and experience building fully integrated offshore vessels and equipment.

One integrated vessel

We can provide one integrated vessel solution as the sole supplier for the ship, mission equipment and control system. We offer a multifunctional solution of cablelay and repair vessel.

  • integrated control system: control system for the mission equipment can be integrated to enable easier operation
  • hybrid propulsion: solutions focused on more efficient fuel consumption
  • large working area on the aft deck
  • focus on the highest level of comfort onboard
  • all cabins have their own private facilities.

Design benefits

The T6000-23 design further elaborates on our previous built vessels and includes features such as a hybrid engine arrangement, higher cablelay speed, and separation between the working and living areas.  A lean approach during the design of material flows and storage has resulted in a vessel sized appropriately for any project. All stages of a cablelay operation have been taken into account, from load-out at the cable manufacturer to burial of the cable into the seabed.

The vessel is equipped with an integrated control system which enables monitoring of all the equipment from the same station, providing easier operation management. The cable control room is located in the aft deck which also gives good visibility over the working area.

The vessel is outfitted with three cable tanks which allow for simultaneous loading resulting in fast load-outs and time savings. The cable is guided from the cable tanks into the cable highway, through the linear cable engine (LCE) or cable drum engine (CDE) before it leaves the vessel over the whiskers into the sea.

Specifications

  • three main cable tanks: max 2,000 tons per tank
  • two spare cable tanks: 140m3 per tank
  • operational depths range from 10 to 8,000 metres (also depending on the cable size and specification).
