ROV tether, towing and seismic cable
Oceanographic instruments, underwater robots and seabed seismic systems need reliable telemetry alongside the power required by the equipment. Fixed underwater routes and moving tethers impose different demands. A towing cable may need seawater-resistant materials and steel or aramid reinforcement; floating and neutrally buoyant constructions can be considered where cable weight affects deployment.
Hybrid subsea cable design
A custom underwater cable can combine power cores, control pairs or quads, Ethernet data elements, bus elements and optical fibres. Air, gas or fluid hoses can also be integrated where the equipment needs them. Designs can accommodate power elements up to 6 kV, data elements up to Cat 7 and strength members rated up to 100 kN, subject to the agreed construction. These are design options, not ratings shared by every subsea cable.
