How often do surface diving decompression chambers and associated piping require a pressure test?

The requirement for surface diving decompression chambers and associated piping to undergo a pressure test annually to the Maximum Allowable Working Pressure (MAWP) is crucial for ensuring the safety and integrity of the equipment used in diving operations. This annual testing helps identify any potential leaks, weaknesses, or structural flaws that may have developed due to wear, fatigue, or environmental factors. Maintaining the chamber and its components at their MAWP is essential for safe operations, as it confirms that the equipment can handle the pressures encountered during diving activities without risk of failure.

Regular pressure testing thus plays a significant role in preventative maintenance and safety. By ensuring that the equipment is tested annually, operators can comply with safety regulations and industry standards, thereby minimizing the risk of accidents and enhancing diver safety. This practice also fosters a culture of safety and responsibility in diving operations, which is vital in high-risk environments like underwater exploration.
