When Henri G. Delauze founded COMEX in 1961, in Marseilles, industrial deep-sea diving did not exist yet. Very soon however, COMEX promoted this new technology and became a pioneer in deep diving operations for the offshore oil industry. For over 30 years, divers of COMEX, world leader in sub-sea engineering and in manned and unmanned sub-sea interventions scoured all the seas on earth and worked at depths of over 300 meters thanks to the use of helium/oxygen in the breathing mixtures.
During the past 20 years, COMEX has continued its development and diversified its activities by entering the robotic and automation fields, with the creation of CYBERNETIX, and the nuclear industry with COMEX NUCLEAIRE. Nowadays, still chaired by H.G. Delauze, COMEX S.A. holding company defines the main orientations and the long and mid term strategy for the COMEX Group. It holds participations in CYBERNETIX and GEOCEAN. COMEX S.A. also manages the activities of the Marseilles based Hyperbaric Experimental Center which features exceptional testing equipment:
 Several automated large hypo and hyperbaric chambers that can be used in hydraulic mode or with various gases (oxygen, helium, hydrogen…)
 A testing pool with a 10 meter deep tank
 A bio-medical and scientific research department, with 40 year experience in physiological studies in hostile environment, equipped with very specific testing instruments.
