High pressure testing system for sonar and sensor technology research

(Ref: SO1007)

This high pressure testing system is designed to test defence and security components under hyperbaric conditions for simulating realistic subsea environmental and operating conditions. The 1270 litre, 100 bar (1450 psi) hyperbaric test chamber has multiple customer-specific connections, ports and penetrations. The closure is held in position whilst with 18 easy-to-handle and position manual chocks.

The pressure test system comprises numerous modules including:


– High pressure testing vessel with a quick-access manual chock closure

– Bund with an integrated hyperbaric test chamber support frame

– Closure parking frame to allow for safe test component change-out

– Access platform

– Fully automated fluid management system


The fully automated fluid management system comprises of the fill drain system and the pressure control system operated by the control panel. The fill drain system simply allows for the pressure test chamber to be filled, purged and drained prior and post testing.

The control panel’s touch screen HMI enables the operator to interface with the PLC which controls the sequence of operations including writing, editing, saving, loading and executing customer-specific test profiles.

Test profiles may include pressurisation to a selected pressure at a defined ramp rate, or a period of stable pressure, or depressurisation to a selected pressure at a specific ramp rate which can all be saved to a library. A cycle is a profile that has been executed from start to finish.

Our experienced engineers installed and commissioned the system and delivered operator training with a full high pressure system package walkthrough including equipment description and functionality, along with essential pressure system safety procedures, practical activities and demonstrations.

We also provided a written scheme of examination in line with the Pressure System Safety Regulations (PSSR:2000) to ensure the pressure system is inspected annually, addressing all points of the relevant standards and legislation for the operation and maintenance of pressure equipment.
