unassailable ‘fit & forget’ pressure moulded cable systems for hostile environments

Surface & Sonar


Scientific Management International designs, manufactures and supplies bespoke pressure moulded cable systems through-hull penetrators and pressure moulded connectors for a wide variety of applications across the most challenging and hostile environments on the planet. We have a record of more than 10,000 installations with zero leaks.

Encapsulated instruments and bespoke cable design form part of our custom solutions for inboard and outboard cable harnesses, winches, masts, communication systems and ship’s sonars. Surface operating conditions and hostile environments increasingly demand materials and processes with proven track records for more than 20 years continuous service which is why our products are so often preferred.


Our range of connectors, glands, harnesses and encapsulated looms provide reliable connectivity for electrical, co-axial, fibre optic and power cables and find favour in a range of sonar applications including bow systems, hydrophones, transducers (pictured), flank array sonar panels and towed sonar systems.

High performance, insulation resistance and low attenuation characterise every design and our completely amalgamated moulding technology ensures leak free lifetime deployments every time.
