The Nexus has been equipped with a cable carrousel with a capacity of 5,000 tonnes to install long export cables. It was normally necessary for the ship to slow down while the repeater was being laid. Cable ships have unique requirements related to having long idle periods in port between cable laying or repairs, operation at low speeds or stopped at sea during cable operations, long periods running astern (less frequent as stern layers are now common), high maneuverability, and a fair speed to reach operation areas. This new vessel is Van Oord's second cable-laying vessel in addition to the Nexus. Cable laying ship RESPONDER sank at around 1740 Seoul time Sep 12, west of southern tip of Tsushima island, East China sea, South Korea, after more than 12-hour long firefighting, reportedly because the ship took on too much water during firefighting, though it doesn’t look this way. GUARD VESSEL. Cable ships also use “plows” that are suspended under the vessel. Thomas N. Sanderlin, Stuart M. Williams & Robert D. A cable-laying ship, like Long Lines, is designed to lay new cables. ACCOMMODATION UNITS. The difficulty with laying repeaters is that there is a bulge where they are spliced in to the cable and this causes problems passing through the sheave. A rope connected in parallel to the repeater went through the sheave which pulled the cable back in to the sheave after the repeater had passed. [7], The most common laying engine in use is the Linear Cable Engine (LCE). Its intelligent cable lay control system will be a further evolution from Nexus. These plows use jets of high-pressure water to bury cable 3 feet under the sea floor, which prevents fishing vessels from snagging cables as thrall their nets.[8].
