    Hyperbaric Medical & Decompression Chambers

    Our range of Hyperbaric Oxygen Therapy Chambers and decompression chambers are meticulously engineered to meet the highest standards of performance and reliability. From compact, portable monoplace chambers for quick response in remote locations to larger, multiplace Hyperbaric Oxygen Treatments (HBOT) chambers, we offer a solution for every scenario.

    These chambers are used in the treatment of conditions such as decompression sickness and carbon monoxide poisoning, by exposing patients to normal air pressure levels higher than atmospheric pressure. Hyperbaric systems also support medical treatments in critical care and emergency response settings, and are an essential part of saturation diving operations. Whether you’re looking to hire or buy, we offer professional guidance to help you select the right system for your needs.

    Frequently Asked Questions

    A Deck Decompression Chamber (DDC) is a pressurised, surface-based vessel used to safely manage the physical effects of deep-water diving. When divers breathe compressed air or mixed gases at depth, inert gases like nitrogen or helium dissolve into their tissues. If a diver ascends too quickly, these gases form microscopic bubbles in the bloodstream, leading to decompression sickness (DCS). A DDC is used to artificially recompress the diver on the surface, dissolving the dangerous bubbles back into the blood, and then slowly decompressing the chamber to allow the body to safely off-gas.

    A twin-lock hyperbaric chamber is divided into two separate pressurised compartments. The primary compartment, known as the main lock, is where the diver rests during their decompression schedule or medical treatment. The secondary compartment, known as the entry lock or transfer lock, is much smaller. This twin-lock design is an essential life-support feature. It allows a Diver Medic Technician (DMT) or essential medical supplies to be pressurised and transferred into the main lock to assist the patient without ever having to depressurise the main chamber and compromise the diver’s treatment.

    In saturation diving, the divers do not return to normal surface pressure for the entire duration of the project, which can last for weeks. Instead, they live inside a massive, specially designed hyperbaric habitat located on the deck of the dive support vessel. The internal pressure of this habitat is exactly matched to the pressure of the working depth. Divers commute to the working depth in a pressurised diving bell that locks directly onto the main hyperbaric chamber. This complex integration allows dive teams to work efficiently at extreme depths without facing the massive physical toll of daily decompression.

    Because the interior of a hyperbaric chamber contains different gas mixtures and is under extreme pressure, safety regulations are incredibly strict. A commercial DDC must be equipped with a Built-In Breathing System (BIBS), which features dedicated masks that supply pure oxygen or mixed gas directly to the diver and immediately exhaust their exhaled breath outside the chamber to prevent toxic carbon dioxide buildup. Chambers must feature real-time O2 and CO2 electronic analysers, two-way communication systems, and hyperbaric fire suppression systems designed to instantly extinguish a flame in a high-oxygen environment.

    Procuring and operating a commercial hyperbaric chamber requires strict adherence to international offshore standards. The primary regulatory guidelines are set by the International Marine Contractors Association (IMCA), specifically documents like IMCA D018 for the testing and certification of diving plant equipment, and IMCA D023 for containerised systems. The steel pressure vessel itself must undergo rigorous, scheduled hydrostatic testing to prove its structural integrity. Additionally, if the chamber is integrated into a containerised dive spread, the external lifting frame must hold a valid DNV certification to guarantee safe transfer via offshore cranes.
