Saturation diving systems allow divers to work for long periods deep underwater. When not working, the divers live in pressurised living quarters replicating the pressure levels at which they work on the seabed. The living chamber resides on the deck of the operating vessel and the divers are transported from there to the seabed via a diving bell without changing pressure. It can take many days for a diver to decompress safely after working at depths of up to 200 meters underwater. The divers can spend up to 30 days at a time living within the pressurised system, decompressing just once at the end of that period.
