Hyperbaric Support Operations
Turnkey decompression chambers, medical locks, and specialist crews.
Turnkey decompression chambers, medical locks, and specialist crews.
Hyperbaric Medical Chambers & Compression Systems
Containerized multi-lock chambers, TBM interventions, diver decompression, and life-support operations.
Operating in high-pressure hyperbaric and subsea environments demands medical-grade life support systems and rigorous pressure vessel certification.
Chow Marine maintains a dedicated fleet of transportable, containerized double-lock hyperbaric decompression chambers certified in accordance with ASME-PVHO-1 (Pressure Vessels for Human Occupancy) and CSA Z275.1 standards.
Our systems are deployed across commercial diving operations, marine civil works, and tunneling projects to provide immediate on-site treatment capability for decompression illness and support planned surface decompression (Sur-D-O2) protocols.
Every hyperbaric system is operated by certified Chamber Operators under the supervision of Diving Medical Technicians (DMTs) and licensed Diving Medical Officers (DMOs), featuring continuous O₂/CO₂ atmospheric gas analysis and hyperbaric fire suppression.
PVHO Pre-Deployment Audit
Hydrostatic pressure testing, seal integrity inspection, and medical gas purity certification.
Life-Support Telemetry Hookup
Integration of primary/secondary breathing air banks, oxygen manifolds, and automated fire extinguishing systems.
Operational Pressurization
Controlled staged pressurization following US Navy / DCIEM decompression and treatment schedules.
Medical Sign-Off & Release
Physician neurological and physiological clearance prior to atmospheric depressurization.

01
Why is an on-site decompression chamber required on marine projects?
add
Why is an on-site decompression chamber required on marine projects?
When divers operate at deeper depths or for extended bottom times, immediate access to a recompression chamber within minutes is legally mandated and medically vital to treat potential decompression sickness (DCS) or arterial gas embolism.
02
What decompression tables do your operators utilize?
add
What decompression tables do your operators utilize?
Our operators are trained in DCIEM (Defence and Civil Institute of Environmental Medicine) Canadian tables, US Navy Diving Manual Revision 7 tables, and proprietary saturation protocols.
03
Can your chambers be mobilized by road on short notice?
add
Can your chambers be mobilized by road on short notice?
Yes. Our chamber units are skid-mounted inside ISO 20-foot shipping containers that can be transported on standard flatbed trailers and mobilized anywhere in Ontario or Quebec within hours.
