What is a Hyperbaric Rescue Chamber (HRC)? - Tuesday, September 6, 2016

The work of a commercial diver is not for the faint of heart. Our profession can be rewarding, but of course, a job that requires working in the high-pressure environment of deep ocean waters is inherently dangerous.


On any given day on the job, a commercial diver must be mindful of both the integrity of his submerged working quarters and the amount of breathable air available. In such unforgiving environments for humans, having a reliable course of action in the event of an emergency is a matter of life and death.

To this end, hyperbaric rescue chambers (HRCs) are an essential piece of equipment while on a deep-water dive. Sometimes called a Hyperbaric Lifeboat (HLB), Hyperbaric Rescue Vessel (HRV), or Hyperbaric Rescue Chamber (HRC), these are essentially a sealed, pressurized diving vessel that can be used as a submersible lifeboat.

The hyperbaric rescue chamber isn’t just useful in emergency situations. During normal operations, the hyperbaric rescue chamber can be utilized as a living chamber, particularly in a portable saturation diving system. Additionally, a standard hyperbaric rescue chamber can boost a wide arsenal of tools and amenities. For the 16-man 1000FSW (305M) Aqua Air HRC, these features include:

  1. Sixteen seats and drawers
  2. Crash frame with holders for 4bottles on each corner, for a total of 16 bottles.
  3. Insulated exterior with reflective aluminum jacketing
  4. Spool piece 24” I.D. x 26” long – mating flange on each side of Sypris Technologies Tube Turns coupling with chain drive
  5. Painted inside and out
  6. Thirty-two penetrators – qty 1 2” NPT and qty 31 ¾” NPT
  7. Aluminum Deck Plates
  8. Two 24” I.D. Manways with hatches

So just how safe is it to use a hyperbaric rescue chamber in the field? Our hyperbaric rescue chambers, including Aqua Air’s 16-Man HRC 1000 FSW (305M), are built in accordance with the following codes and standards:

 

  • ASME Boiler and Pressure Vessel Code Section VIII Division 1 and 2
  • ASME-PVHO-1 Safety Standard for Pressure Vessels for Human Occupancy
  • ABS-Rules for Building and Classing Underwater Vehicles, Systems, and Hyperbaric Facilities.

 

In other words, just as you would never drive a car without a seatbelt, a hyperbaric rescue chamber plays an invaluable role in keeping divers safe.
