STS Subsea

STS Subsea designs and manufactures highly-specialised, bespoke connectors, electrical umbilicals, cables and antennas designed for use in under-sea or harsh environments.

We offer a complete prototyping service, from design and manufacture to electrical and pressure testing to 10,000psi, with an on-site moulding service and an over-moulding material capability for Polyurethane, Neoprene and Polyethelene components, as well as metal to glass seals designed to prevent water ingress to a depth of up to 3600 metres.

Under-sea examples include specialised applications such as the hull-penetrator, cable and antenna for the Astute submarine’s UHF and SARSAT distress beacon and a 300m sea cable – carried with a moulded strain-relief connector – for the winch on the 2093 mine-hunting sonar which incorporates a combined hydraulic/electrical cable assembly.

Just above the water, solutions include the cable harnesses for an array of deep ocean meteorological buoys.

Our customers include many Defence prime contractors, the British and overseas navies, and world leading oceanographic research organisations.

One of the core capabilities of STS Subsea is adapting commercially available products for use in subsea and harsh environments, tailored to specific customer needs. As a consequence we have developed various standard product ranges that are available from stock or on very short lead times :-
