COMEX has been awarded the new contract for the operational maintenance of the hyperbaric chambers used by the French Navy and the French Army. Awarded on May 21, 2026, this multi-year contract extends a partnership that began in 2009 around strategic equipment supporting military hyperbaric operations.
This renewal confirms the trust placed in COMEX to ensure the availability, safety and compliance of critical hyperbaric installations, deployed in particular at the naval bases of Brest, Cherbourg, Toulon, Saint-Mandrier and Roscanvel.
A strategic contract to ensure the availability of hyperbaric assets
In the military sector, operational maintenance goes beyond standard technical servicing. Its purpose is to ensure that equipment remains available, safe and compliant with regulatory requirements, including in demanding environments where responsiveness and reliability are essential.
The hyperbaric chambers covered by this contract play an important role in supporting diving, recompression and intervention operations. Their availability is therefore a major operational issue for the armed forces.
The new contract covers around forty hyperbaric systems, including different generations of recompression chambers — among them the new CX1800 generation — as well as a saturation diving system. This scope reflects COMEX’s ability to support hyperbaric equipment of different generations over the long term, while integrating the latest technical developments.
Comprehensive expertise in defense hyperbaric MRO
Under this contract, COMEX provides preventive and corrective maintenance services, on-site technical interventions, spare parts supply, and support for regulatory requalification operations.
COMEX teams also manage obsolescence issues and propose technical upgrades whenever necessary. This ability to support installations over the long term, anticipate technical developments and maintain a high level of responsiveness is a central component of the contract.
Defense hyperbaric MRO requires highly specialized expertise. These systems are subject to regulations specific to hyperbaric operations, including the applicable requirements governing hyperbaric interventions, as well as strict obligations in terms of safety, traceability and compliance. In this context, COMEX’s long-standing knowledge of the installations is a decisive advantage.
Design, maintenance and continuous improvement
One of COMEX’s key strengths lies in its dual expertise: designing hyperbaric installations and ensuring their operational maintenance. This comprehensive approach enables its teams to gain an in-depth understanding of the systems they maintain, identify technical constraints, and propose solutions tailored to the customer’s operational needs.
The gradual integration of new-generation chambers also marks an important milestone. It reflects evolving requirements, the introduction of new equipment, and the need to ensure continuity between legacy installations and the latest hyperbaric systems.
This approach is part of a continuous improvement process, supported by ongoing technical monitoring of components, obsolescence issues, regulatory requirements and operating conditions.
A long-standing relationship built on trust
Since 2009, COMEX has been supporting the French Navy in the operational maintenance of its hyperbaric installations. This latest renewal reflects a long-standing relationship built on trust, grounded in technical expertise, operational excellence, team responsiveness, and the quality of the relationship developed over the years.
In an environment as demanding as Defense, continuity of service, confidentiality and intervention capability are essential. COMEX therefore remains fully committed to supporting the armed forces by keeping hyperbaric equipment available, compliant and suited to operational requirements in the field.
COMEX, a trusted partner for critical hyperbaric installations
Through this new contract, COMEX confirms its position as a trusted partner for the operational maintenance of critical hyperbaric installations.
This expertise serves not only defense stakeholders, but also professional diving operators, hyperbaric centers, and operators of pressurized equipment requiring a high level of safety, compliance and availability.
With this renewal, COMEX reaffirms its commitment: to support its customers over the long term in the operation, maintenance and evolution of their hyperbaric installations, including in the most demanding environments.
