Saturation diver working on the USS Monitor wreck at 70 m (230 ft) depth. Saturation diver conducts deep sea salvage operations. Saturation diving is diving for periods long enough to bring all tissues into equilibrium with the partial pressures of the inert components of the breathing gas used.
Herbert Nitsch (born 20 April 1970) is an Austrian freediver, the current freediving world record champion, and "the deepest man on earth" [1] having dived to a depth of 253.2 meters (831 feet). Nitsch has held 34 world records in all of the eight freediving disciplines recognised by AIDA International and one in the traditional Greek ...
In 2011, divers completed a 1,000 fsw saturation dive to evaluate the new Navy's Saturation Fly-Away Diving System (SAT FADS). [36] The SAT FADS was designed in 2006 as a portable replacement of two decommissioned Pigeon-class submarine rescue vessels. [36] In March 2022, CDR Dustin Cunningham took up his appointment as Commanding Officer of ...
COMEX diving bell. COMEX (or Compagnie Maritime d'Expertises) is a French company specializing in engineering and deep diving operations, created in November 1961 by Henri-Germain Delauze and run by him until his death in 2012. This company is known worldwide for its technology in regard to underwater exploration at great depths. [citation needed]
Saturation diving is a procedure used to reduce the high-risk decompression a diver is exposed to during a long series of deep underwater exposures. By keeping the diver under high pressure for the whole job, and only decompressing at the end of several days to weeks of underwater work, a single decompression can be done at a slower rate ...
Once saturation is achieved, the amount of time needed for decompression depends only on the depth and gases breathed. This was the beginning of saturation diving and the US Navy's Man-in-the-Sea Program. [1] The first two phases of Project Genesis involved exposing animals to saturation in various breathing gases.

Last Breath is a 2019 British documentary film directed by Richard da Costa and Alex Parkinson. It relates the story of a serious saturation diving accident in 2012, when diver Chris Lemons had his umbilical cable severed and became trapped around 100 metres (330 ft) under the sea without heat or light, and with only the small amount of breathing gas in his backup tank.
Hydrox, a gas mixture of hydrogen and oxygen, is occasionally used as an experimental breathing gas in very deep diving. [1] [2] It allows divers to descend several hundred metres. [3] [4] [5] Hydrox has been used experimentally in surface supplied, saturation, and scuba diving, both on open circuit and with closed circuit rebreathers. [6]
