Remote Operation Vehicles

We specialise in the design and manufacture of custom subsea cables for Remotely Operated Vehicles (ROVs) and other underwater systems.

Get in touch

With decades of experience in harsh-environment cable technology, our engineering team delivers high-performance, bespoke cable assemblies tailored to the demanding requirements of subsea exploration, offshore energy, defence, and marine science sectors.

Every ROV system is unique, and so are its connectivity needs. We work closely with clients to develop fully customised cable solutions that integrate:

• Power transmission (low and high voltage)
• Data and signal lines (including twisted pairs, coax & serial comms)
• Fibre optic elements for high-bandwidth communication
• Load-bearing and strain members

• Buoyancy control (neutral or positive)
• Protective armouring and anti-vibration features

Whether you need a lightweight tether, a reinforced umbilical, or a multi-functional hybrid cable, we design each solution from the ground up to match your exact operational environment and performance goals

Built for the Harshest Environments

Our subsea cables are engineered to thrive in challenging marine conditions, including:

• Deepwater pressure environments
• Constant flexing and dynamic loads
• Saltwater corrosion
• Extreme temperatures
• Prolonged service life (typically 25 years)

We use advanced materials and precise manufacturing techniques to ensure durability, flexibility, and performance over long deployments. Optional armour layers, water-blocking features, and custom jacketing ensure your cables are ready for long-term subsea operation.

In-House Design & Rapid Prototyping

Get in touch

Concept Cables offers a fully integrated design and manufacturing service:

• CAD and simulation-based cable design
• Rapid prototyping for short development cycles
• Low to medium production volumes starting from as little as 100m
• Custom testing programs including electrical, optical, mechanical, and environmental

We’re proud to work as an extension of your engineering team—providing responsive, expert support from concept to final delivery.

ROV Cable Applications Include:

• ROV main umbilicals and tethers
• Towed sensor arrays and sonar systems
• Underwater cameras and lighting systems
• Subsea data acquisition systems
• Diver communications
• Subsea instrumentation and control

Our solutions are trusted by customers operating in offshore energy, renewables, defence, oceanographic research, and commercial diving.

Quality You Can Depend On

As an ISO 9001:2015 certified manufacturer, quality and consistency are central to our process. All cable assemblies are produced in the UK at our Dorset-based facility, where we carry out rigorous inspection and testing before shipment. Custom acceptance testing and documentation can be provided as required for regulated or mission-critical applications.
