Saturation diving system

A saturation diving system is the combined and installed equipment required to support a saturation diving operation. It may be an underwater habitat, or more commonly for commercial diving operations, a hyperbaric habitat complex, known in the industry as a saturation spread, assembled on a surface platform, supported by a range of surface support equipment, some of which is common to other surface-supplied diving activities, and some of which is used mostly or only for saturation diving. Much of the equipment can be classed as life-support equipment, and some of it is required for emergency and rescue functions.

The basic components include living space accommodations for the divers when they are not diving, with sanitation facilities and a means of providing supplies to the occupants. There are also facilities for compression and decompression, treatment of dysbaric maladies, transfer under pressure between accommodation and closed bell transportation modules for transport between the accommodation and workplace, and for emergency evacuation. Units are interconnected by trunking and can be isolated by airlock doors.
