Subsea Pressure Testing Services

SCS facilitates a professional pressure test facility available for rental to clients requiring independent, third-party verification of their subsea equipment. Whether you are validating a new product design, qualifying components for a specific depth rating, or stress-testing assemblies before offshore deployment, the facility we use provides a controlled, professionally managed environment for accurate, repeatable results.

The Pressure Chamber

Our chamber is rated to 600 bar (equivalent to a water depth of 6,000 metres) and can accommodate a wide range of subsea components and assemblies.

Internal diameter: 400mm
Internal length: 1,000mm
Maximum pressure: 600 bar
Maximum ramp rate: 100 bar/min

A rapid open/close mechanism reduces turnaround time between tests, improving efficiency and reducing costs where multiple test cycles are required.

Live Electrical Testing Under Pressure

The chamber is fitted with three electrical ports, enabling functional testing of active systems throughout the pressurisation process – not just before and after. This allows SCS to verify the performance of cameras, lights, sensors and other electronic systems under simulated deep-sea conditions in real time.

Available electrical testing under pressure includes:

Insulation resistance (IR) testing
DC resistance testing
Ethernet speed testing
High voltage flash testing
Cable integrity testing
Cable fatigue testing
Cable cycle testing

An internal camera can be installed during testing to provide live visual monitoring of the equipment under test, giving engineers direct insight into how systems behave as pressure increases.

Test Reporting

Every test is conducted by an experienced team and documented in a detailed test report that covers all critical parameters, including the maximum pressure achieved, hold times, and ramp rates. Reports are suitable for use in product qualification, compliance documentation and client-facing deliverables.

Tests are carried out by a third-party partner.

Who Uses This Service?

Subsea pressure testing is relevant across a range of sectors and applications:

Subsea technology developers – product qualification and design validation
Camera, sensor and lighting manufacturers – depth rating vertification
Cable and connector suppliers – pre-deployment component vertification
Offshore energy contractors – pre-deployment component vertification
Research and defence – performance testing under extreme pressure conditions

Why SCS?

Our facility combines a high-specification pressure chamber with an experienced technical team and a straightforward rental process. We work to your test requirements, provide full documentation, and turn tests around efficiently, minimising disruption to your development or delivery schedule.
