A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, for electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves[1] for guiding cable over bow or stern or both. Bow sheaves,[2] some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS Cable Innovator at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS Long Lines.[3]
The first transatlantic telegraph cable was laid by cable layers in 1857–58. It briefly enabled telecommunication between Europe and North America before misuse resulted in failure of the line. In 1866 the SS Great Eastern successfully laid two transatlantic cables, securing future communication between the continents.
Modern cable ships
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.[4]
Modern cable ships differ greatly from their predecessors. There are two main types of cable ships: cable repair ships and cable-laying ships. 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. A cable-laying ship, like Long Lines, is designed to lay new cables. Such ships are bigger than repair ships and less maneuverable; their cable storage drums are also larger and are set in parallel so one drum can feed into another, allowing them to lay cable much faster. These ships are also generally equipped with a linear cable engine (LCE) that helps them lay cable quickly. By locating the manufacturing plant near a harbor, cable can be loaded into the ship's hold as it is being manufactured.[5]
The newest design of cable layers, though, is a combination of cable-laying and repair ships. An example is USNS Zeus (T-ARC-7) the only U.S. naval cable layer-repair ship. Zeus uses two diesel-electric engines that produce 5,000 horsepower (3,700 kW) each and can carry her up to 15 knots (28 km/h; 17 mph). She can lay about 1,000 miles (1,600 km) of telecommunications cable to a depth of 9,000 feet (2,700 m). The purpose of Zeus was to be a cable ship that could do anything required of it, so the ship was built to be able to lay and retrieve cable from either the bow or the stern with ease. This design was similar to that of the first cable ship, Great Eastern. 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.[6]
Equipment

To ensure that cable is laid and retrieved properly, specially designed equipment must be used. Different equipment is used on cable-laying ships depending on what their job requires. In order to retrieve damaged or mislaid cable, a grapple system is used to gather cable from the ocean floor. There are several types of grapples, each with certain advantages or disadvantages. These grapples are attached to the vessel via a grapple rope, originally a mix of steel and manila lines, but now made from synthetic materials. This ensures that the line is strong, yet can flex and strain under the weight of the grapple. The line is pulled up by reversing the Linear Cable Engine used to lay the cable.[7]

The most common laying engine in use is the Linear Cable Engine (LCE). The LCE is used to feed the cable down to the ocean floor, but this device can also be reversed and used to bring back up cable needing repair. These engines can feed 800 feet (240 m) of cable a minute. Ships are limited to a speed of eight knots (15 km/h) while laying cable to ensure the cable lies on the sea floor properly and to compensate for any small adjustments in course that might affect the cables' position, which must be carefully mapped so that they can be found again if they need to be repaired. Linear Cable Engines are also equipped with a brake system that allows the flow of cable to be controlled or stopped if a problem arises. A common system used is a fleeting drum, a mechanical drum fitted with eoduldes (raised surfaces on the drum face) that help slow and guide the cable into the LCE.[7] Cable ships also use “plows” that are suspended under the vessel. These plows use jets of high-pressure water to bury cable three feet (0.91 m) under the sea floor, which prevents fishing vessels from snagging cables as thrall their nets.[8]
HMTS Monarch[9] (renamed CS Sentinel 13 October 1970)[1] completed the first transatlantic telephone cable, TAT-1, in 1956[10] from Scotland to Nova Scotia for Britain's General Post Office (GPO).

The Ocean Marine System Group used a cable laying software designed by Makai Ocean Engineering Inc., in five of their cable installation and repair vessels. The MakaiLay software has been used by 90% of the worlds' global fleet of cable ships. These five OMS vessels were installed with this software on August 23, 2023, to reduce failures during installation and increase reliability, safety, speed, and accuracy:[11]
- CS Cable Vigilance
- CS Île de Ré (Formerly Alcatel/Alcatel-Lucent/Nokia ship)
- CS Lodbrog (Formerly Alcatel/Alcatel-Lucent ship)
- CS Teneo

Repeaters
When coaxial cables were introduced as submarine cables, a new issue with cable-laying was encountered. These cables had periodic repeaters inline with the cable and powered through it. Repeaters overcame significant transmission problems on submarine cables. 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. British ships, such as HMTS Monarch and HMTS Alert solved the problem by providing a trough for the repeater to bypass 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. It was normally necessary for the ship to slow down while the repeater was being laid.[12] American ships, for a time, tried using flexible repeaters which passed through the sheave. However, by the 1960s they were also using rigid repeaters similar to the British system.[13]
Another issue with coaxial repeaters is that they are much heavier than the cable. 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.[13][12]: 212

During this operation, 2,500 nautical miles (4,600 km; 2,900 mi) of cable were stored on each ship, but 300 feet (91 m) of cable was lost over a region known as Telegraph Plateau in the North Atlantic with depths nearly 10,500 ft (3,200 m). Attempts with USS Niagara failed twice that year and work was abandoned, until next year, both ships met in the mid-Atlantic for spicing of their cables and HMS Agamemnon traveled east towards Valentia Island. Additional breakage in the cable occurred and another attempts to lay the cabling were sort of successful. A failure occurred in the installed cable after a month due to engineer mishandling causing damaged.[14]
