Hyperbaric lifeboat
Hyperbaric lifeboat is a life-saving vessel designed for the evacuation of divers in a decompression environment. It is a critical component of saturation diving operations, where divers live and work at pressure for extended periods.
Design and Function[edit | edit source]
A hyperbaric lifeboat is designed to maintain an internal pressure environment that matches the pressure of the saturation system. This allows divers to evacuate from a diving support vessel (DSV) or a diving bell in an emergency without undergoing rapid decompression, which can lead to decompression sickness.
The lifeboat is equipped with life-support systems, including air supply, temperature control, and waste management facilities. It also has communication systems to maintain contact with the DSV or shore-based support.
Use in Saturation Diving[edit | edit source]
In saturation diving, divers live in a pressurized environment for the duration of their work period. This can last for several days or even weeks. The divers are decompressed to surface pressure only once, at the end of their work period. This method reduces the risk of decompression sickness but requires a safe method of evacuation in case of an emergency. The hyperbaric lifeboat fulfills this requirement.
Safety Regulations[edit | edit source]
Hyperbaric lifeboats are subject to stringent safety regulations. They must be capable of maintaining life-support for a specified period, typically 72 hours, and must be able to withstand the pressures of the diving depth. They must also be capable of self-righting if capsized and have sufficient buoyancy to remain afloat even if damaged.
