Transportable Recompression Chamber System (TRCS)


Introduction From usmilitary.about.com & cowanmfg.com.au


The TRCS is a combination of two pressure vessels used to treat divers suffering from decompression sickness and air embolisms. One vessel, the conically shaped Transportable Recompression Chamber (TRC) is used as the emergency evacuation chamber and for decompressing divers.
The standard Transfer Lock (TL) can accommodate 2 people (Modified Transfer Lock - 5 people) and is designed to transfer people, normally medical personnel, in and out of the TRC. It is capable of an operating depth equivalent to 70 metres while supporting both occupants on oxygen and air for an unlimited period (most dive tables are to a maximum of 6 hours).
The two vessels, TRC and TL are connected by a freely rotating NATO flange coupling. The vessels are supported with individual oxygen/air support racks used to supply and control oxygen/air to personnel in the vessels. The TRCS will be transportable by various ground, ship, and air transportation. This will enable a diver to receive prompt medical treatment when located at a remote site.

Unit 3) talk with a "patient" inside a transportable recompression chamber system (TRCS) during Exercise Kernel Blitz '97.
These devices are used on divers who are brought to the surface too quickly for the body to properly decompress. The chamber recompresses the diver to a safe depth, and then slowly recompresses to normal pressure. Exercise Kernel Blitz '97. was an exercise near the Southern California coast designed to train U.S. Sailors and Marines and Canadian and Australian troops in amphibious operations.

(TRCS)170k Pacific Ocean, 16 July 2004 - Hull Maintenance Technician 2nd Class Justin Culver, a Navy Diver assigned to Mobile Diving Salvage Unit One (MDSU-1), exits the Transportable Recompression Chamber System (TRCS), aboard USNS Sioux (T-ATF 171), after completing his decompression obligation during mixed gas diving salvage operations during exercise Rim of the Pacific (RIMPAC) 2004.
Sioux is one of the seven fleet ocean tugs operated by the Navy's Military Sealift Command. They are part of MSC's Naval Fleet Auxiliary Force operating in direct support of U.S. Navy fleets deployed around the world. RIMPAC is the largest international maritime exercise in the waters around the Hawaiian Islands. This year's exercise includes seven participating nations; Australia, Canada, Chile, Japan, South Korea, the United Kingdom and the United States. RIMPAC is intended to enhance the tactical proficiency of participating units in a wide array of combined operations at sea, while enhancing stability in the Pacific Rim region.
