Construction & Utilities
From the ocean floor to the surface, Concept Cables delivers the specialist connectivity that keeps marine innovation moving.
Our custom subsea cables power and protect critical systems across ROV operations, diving support, aquaculture, oceanography, renewables, and scientific research.
Built to withstand the harshest marine environments, our solutions ensure reliable performance where it matters most – helping you explore, protect, and harness the ocean with confidence.
With decades of experience and a commitment to innovation, we work as an extension of your engineering team—designing, testing, and manufacturing cables tailored to your exact operational needs. From rapid prototyping to long-term deployments, Concept Cables combines technical expertise with proven reliability, ensuring your mission beneath the waves is backed by world-class connectivity.
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.
Engineered for Harsh Environments
Our subsea cables are built to survive where others fail. Offering outer jackets that are resistant to abrasion, saltwater and biofouling with UV-stable polymers. Neutral or positive buoyancy control, together with anti-vibration straked designs, ensures stable operation in dynamic waters. Protective armour layers provide robust defence against constant movement and impact while advanced strain-relief members and water-blocking barriers safeguard internal conductors from ingress at depth and provide pressure-resistant construction.
Our cables deliver long service life under the combined stresses of corrosion, flexing, and deepwater loads.
From Concept to Delivery
Achieving this level of reliability starts with our integrated approach to design and manufacturing. Using advanced CAD tools and simulation, we prototype bespoke solutions rapidly, enabling short development cycles without compromising quality. Production volumes can be scaled from short runs to larger projects, while every assembly is subject to rigorous in-house electrical, mechanical, and environmental testing. As an ISO 9001:2015 certified manufacturer, we ensure full traceability and consistency throughout, delivering cables that perform exactly as intended in the toughest marine applications.
We deliver innovative, high-quality, sustainable cable solutions. Rigorously tested, ISO-certified, reliable, and tailored to meet each customer’s precise, long-term needs.
