Test equipment
Composite cylinders for underwater applications

To simulate the influence of immersion, two solutions are available: either hyperbaric chambers are used, or sea trials are carried out. Given the high cost of offshore operations and the difficulties of instrumentation, onshore testing is preferred. Equipment that simulates the effect of pressure has been developed to verify the environmental resistance of subsea equipment. This equipment, commonly known as "hyperbaric chambers", comes in a variety of sizes and capacities.
