We are using the dive table DECO 2000.It is valid from sea level to a height of 700 m. In underwater diving activities such as saturation diving, technical diving and nitrox diving, the maximum operating depth (MOD) of a breathing gas is the depth below which the partial pressure of oxygen (pO 2) of the gas mix exceeds an acceptable limit.This limit is based on risk of central nervous system oxygen toxicity, and is somewhat arbitrary, and varies depending on the diver training . In Sealab II teams of 10 divers stayed underwater for periods of 15 days in a depth of 70 meters. . That depth is the equivalent of approximately 10 NBA basketball courts aligned vertically. Once the divers return to the sat system post diving . An aspiring saturation diver must dive a minimum number of hours at a variety of depths within the air range (0-50M). Compression arthralgia is generally a problem of deep diving, particularly deep saturation diving, where at sufficient depth even slow compression may produce symptoms. This is possible because the diver's body becomes saturated with inert gas, preventing the formation of bubbles. A diver needs to gradually descend or ascend from and to a depth or they can easily get injured by decompression sickness. We should note that depth pay is for air and mixed gas diving.

In this study we examined the hydration status of 11 male divers over 19 days of a commercial saturation diving campaign to a working depth of 74 m, using two non-invasive methods: bioelectrical impedance analysis (BIA) and urine specific gravity (USG). Answer (1 of 3): I will let you in on a not-so-well-kept little secret that divers learn after a time: water will NOT crush a SCUBA diver and kill them no matter how deep they go. The dynamic positioning system of the diver support vessel crashed, and the ship drifted away from the working place, while one diver's umbilical became snagged on a steel platform and was severed. SAT divers live for up 28 days in a small topside chamber that is pressurized to the same level as the underwater construction environment, so divers do not have to decompress after each shift.
