To ensure that they sink at the same rate as the cable (which can take some time to reach the bottom) and keep the cable straight, the repeaters are fitted with parachutes.[12][11]:212. The Netherlands The vessel is able to mobilise a power cable-lay spread to undertake subsea inter array cable laying. Cable laying vessels; ROV Ploughs cutters and jetters; Deck operations roles and responsibilities; The role of subsea survey in the cable laying process from route planning, through to post lay inspection. Cable repair ships, like the Japanese Tsugaru Maru, tend to be smaller and more maneuverable; they are capable of laying cable, but their primary job is fixing or repairing broken sections of cable. Different equipment is used on cable-laying ships depending on what their job requires. The names of cable ships are often preceded by "C.S." MULTICAT / SHOALBUSTER / WORKBOAT. [7], The most common laying engine in use is the Linear Cable Engine (LCE). Cable-laying vessels IHC supplies cable-lay vessels to perform a wide range of tasks. Zeus was built to be as maneuverable as possible so that it could fulfill both roles: as a cable layer or a cable repair ship. ROTTERDAM, the Netherlands – Van Oord has contracted Vard in Norway to build a DP-2 cable-laying vessel.
