The Cable Repair Ship performs maintenance on the Sound Surveillance System (SOSUS) which is a network of strategically placed sonar sensors that provide early warning of submarines. The T-ARC class is capable of laying and retrieving deep water acoustic cables, and is also capable of supporting oceanographic research.
USNS Zeus is the only active Cable Repair Ship in the U.S. Navy. ZEUS is the first multi-mission cable ship designed and built by the U.S. Navy specifically as a cable ship.
It incorporates advanced propulsion features, centralized integrated displays for monitoring ship and cable machinery parameters and functions, passive flume stabilization, better maneuverability and cable handling capabilities at both bow and stern, and survey equipment designed to combine high performance and versatility with minimal maintenance.
Main propulsion is diesel-electric ( GM diesels), rated horse power is ten thousand (five thousand to each of two shafts), five main generators (GE), and four motor generators.
ZEUS combines the main propulsion system with bow and stern-mounted tunnel thrusters in an integrated control system which provides the precise trackkeeping and position holding capabilities required for cable laying and repair, array laying operations, projector towing, acoustic surveys, and other mission tasks.
Application of roll dampening techniques enable the ship to provide a stable platform for safe cable operations at slow speeds up to the maximum permissible sea states specified for each mission.
The Global Cable repair ship market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
USNS ZEUS cable repair ship
The Military Sealift Command operates ships manned by civilian crews and under the command of a civilian master. These ships, indicated by the blue and gold bands on their stack, are “United States Naval Ships” vice “United States Ships” as is the case of commissioned ships.
USNS ZEUS is fitted with a wide array of cable handling equipment including 5 cable tanks, cable transporters, DO-HB tension machines, self fleeting cable drums, overboarding sheaves, and dynamometer cable fairleader.
The secondary mission of the USNS ZEUS is Oceanographic Survey. USNS ZEUS is fitted with both single beam and multi-beam (SIMRAD EM 121) sonars for bottom profiling and can deploy towed sidescan sonars and camera sleds.
CTD systems and deployed Acoustic Measurement Buoys (AMB) and Environmental Measurement Buoys (EMB) provide data measurement of the ocean environment.
In a major initiative to harden deployed systems, the USNS ZEUS will be fitted with a Heavy Overboarding System (HOS). The HOS is a 32.5 metric ton A-frame designed and built by Soil Machine Dynamics, Ltd.. This system is designed to handle and deploy the CRS I & II, free swimming Remotely Operated Vehicles (ROVs), the Sea Tractor, a bottom crawler, and the Sea Plow.
