Diving chamber

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.

Uses
  • Diver training

  • Surface decompression
  • Saturation diving
  • Diving physiology research

There are two main functions for diving chambers:

  • as a simple form of submersible vessel to transport divers underwater and to provide a temporary base and retrieval system in the depths;
  • as a land, ship or offshore platform-based hyperbaric chamber or system, to artificially reproduce the hyperbaric conditions under the sea. Internal pressures above normal atmospheric pressure are provided for diving-related applications such as saturation diving and diver decompression, and non-diving medical applications such as hyperbaric medicine.
