A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants. [1] There are two main functions for diving chambers:
A deck decompression chamber (DDC), or double-lock chamber is a two compartment pressure vessel for human occupation which has sufficient space in the main chamber for two or more occupants, and a forechamber which can allow a person to be pressurised or decompressed while the main chamber remains under constant pressure.
Saturation diving is normally done from a saturation system on a diving support vessel or an offshore platform.While under saturation, the divers cannot be decompressed quickly in response to an emergency as that would be rapidly fatal, and though unusual, emergencies requiring personnel evacuation have occurred on such platforms due to extreme weather or accidents.
INS Nireekshak (A15) (Inspector) is a diving support vessel (DSV) of Indian Navy.It can also function as interim submarine rescue vessel (SRV).. Nireekshak was originally built by M/S Mazagon Dock Limited, Mumbai, for the Oil and Natural Gas Corporation's offshore oil exploration work, having a dynamic position facility and a recompression chamber.
A diving bell is a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work. The most common types are the open-bottomed wet bell and the closed bell, which can maintain an internal pressure greater than the external ambient. [1]
The "saturation system", "saturation complex" or "saturation spread" typically comprises either an underwater habitat or a surface complex which includesof a living chamber, transfer chamber and submersible decompression chamber, [45] which is commonly referred to in commercial diving and military diving as the diving bell, [46] personnel ...

The American Society of Mechanical Engineers defines a Pressure Vessel for Human Occupancy (PVHO) as a container that is intended to be occupied by one or more persons at a pressure which differs from ambient by at least 2 pounds per square inch (0.14 bar). [1]
