Saturation (SAT) diving work is a small community of experienced divers who have a significant amount of SAT-specific training. SAT divers are pre-pressurized in specialized decompression chambers that double as living facilities equipped with bunks, dining areas, and bathrooms. SAT divers are lowered to the jobsite in a pressurized diving bell that then brings them back to their living chamber. Saturation diving is used primarily in the offshore sector, particularly in deeper waters, as in the case of the Russian Submarine Kursk. Most individuals become eligible for SAT consideration after working several years into their diving career.
