It’s official: in November 2025, Septentrion Environnement was certified to provide training and issue the Hyperbaric Aptitude Certificate (CAH) with a B rating for “techniques, sciences, and other interventions” for classes 0, I, II, and III.
The Hyperbaric Aptitude Certificate is a regulatory qualification that certifies that a professional is fit to work in a hyperbaric environment (an environment where the pressure is higher than at sea level and in open air). Using the Institute’s technical facilities, Septentrion Environnement’s team of trainers and professional divers can now welcome trainees to practical training courses designed to develop operational skills in scientific diving.
Our trainers, professional divers, and scientists can now assist you in acquiring and renewing your Hyperbaric Diving Certificate (CAH) Mention B. This recognition marks a new step in our commitment to sharing our expertise and supporting professionals in developing their skills through certified professional training
