Built to the same exacting standards as our sonar systems, GeoAcoustics provides high-reliability cable moulding and overmoulding solutions for subsea equipment manufacturers, marine systems integrators, and offshore contractors.
Following the acquisition of a specialist cable moulding company near our Great Yarmouth headquarters, we have significantly expanded our capability, enabling complex multi-connector assemblies and bespoke mouldings for a wide range of marine and subsea applications.
Integral resillience
Designed for harsh offshore and underwater environments, our overmoulded and potted cable assemblies are engineered to withstand pressure, saltwater ingress, abrasion, and mechanical shock. By fully encapsulating the cable termination, the moulding process creates a seamless watertight seal that protects electrical integrity throughout the life of the deployment.
Critical applications
For sonar transducers, ROVs, AUVs, and subsea sensor packages operating at depth, cable reliability is critical. A failed termination can mean lost data, costly downtime, or even loss of equipment. GeoAcoustics moulded cable assemblies are designed to eliminate these weak points and deliver dependable long-term performance in demanding subsea applications.

How our process works
1 / Requirements & Design
We work with you to understand your application, environment, cable type, connector interface, depth rating, and any specific standards compliance required.
2 / Material Selection
We specify the optimal mould or potting material (TPE, TPU, polyurethane, silicone, or epoxy), matched to your operating environment and mechanical requirements.
3 / Tooling & Prototyping
Mould tooling is designed and fabricated. Prototype assemblies are produced and reviewed with you before sign-off, ensuring the design is optimal before volume production.
4 / Production
Full-scale production at our dedicated cable moulding facility in Great Yarmouth. Experienced specialists oversee every assembly using precision processes and quality-controlled materials.
5 / Test & Despatch
Watertight integrity and electrical testing on every unit. Full documentation supplied. Competitive lead times without compromising on the quality our customers depend on.
Why
choose
us?
Water Ingress Protection
We deliver watertight seals rated for the full pressure range of marine survey depths, from surface installations to deep-towed systems.
Signal Fidelity
High quality encapsulation maintains shielding continuity and eliminates microphonic noise, which is critical for acoustic sensor cables where signal integrity is paramount.
Mechanical Durability
Strain relief and overmoulding distribute mechanical loads, preventing fatigue failure at the conductor-termination interface during repeated deployment cycles.
Chemical Resistance
Our material selection matches to the deployment environment, with saltwater, hydraulic fluids, bilge environments, and fuel-contaminated water all accounted for.
Abrasion & Impact Resistance
Protects against deck handling impacts, vessel-side contact, and seabed contact during towed operations or AUV recovery.
