Hyperbaric Test Center
The Hyperbaric Testing Center has always integrated the technological developments that make it a unique research, testing, measurement and validation centre
The center welcomes actors from the underwater industries, offshore oil and gas, offshore construction, mechanical, nuclear, aeronautics, Defence, space, medical and scientific research.
A unique test platform
Comex Experimental Hyperbaric center (CEH) in Marseille features outstanding testing and trial facilities. All its pressure vessel are made available to its customers for the qualification of equipment and methods of human intervention in extreme environments.
The center extends its activities to any internal or external pressure material testing. These tests are carried out in a series of chambers, with various working pressures and of different sizes, suitable for equipment with volumes ranging from a few deciliters to several cubic meters..

CE 6 300
Working Pressure : 630 bars
Working Pressure : 80 bars
Hydrostatic test can be performed up to 80b in those pressure vessels assembly. As per project needs, 1, 2 or 3 spheres can be used at the time, using watertight doors. Numerous technical flanges are available for feedthroughs. Adaptations are possible to control and automate environmental parameters such as pressure, temperature. Can be requalified to perform human dry & wet simulated dives..
CE 4 000
Working Pressure : 400 bars
Volume : 8 m3
This sphere is dimensioned to simulate up to 4000 meter depth (400b WP). Consisting of two horizontally bolted steel hemispheres, it was originally designed to test civilian submarine hulls, but it also can be operated to assess the pressure performances of any other equipment or material
CE 2 500
Working Pressure : 250 bars
It is a hemispherical chamber, sized to simulate up to 2500 meter depth (250b WP). It is specially adapted to test small components in a liquid environment.
Adaptations are possible to control and automate compression, stop pressure-hold and decompression phases.
CE 1 000
Working Pressure : 70 bars
Dimension : Ø 1 m / L 1.8 m
This cylindrical horizontal chamber allows to simulate up to 700 meter depth (70b WP). It features a full diameter access door, a viewing porthole and various feedthroughs for fluids and electricity..
This means of hydrostatic tests is specially adapted to test medium-sized equipment of R.O.V. type, manipulator arm, umbilicals, junction box, etc.
Adaptations are possible to control and automate compression, level-hold and decompression phases.
