Unique Group’s Diving & Life Support division has recently delivered a state-of-the-art, Zone 2 rated, Classed Surface Nitrox Dive system to FSDS Diving Services, the Asian based subsea service provider.

The diving system supplied was ABS Classed, ATEX Zone 2 certified, IMCA compliant and rated to -20 degrees Celsius. The system comprised an 1800 decompression chamber, a dive control and client area, a machinery and a gas storage space, each housed in EN12075 offshore lift containers. A pair of hydraulic zone rated open cage diver LARS units were provided with the system.

Zone rated systems are typically required on diving projects on FPSO’s when there is risk of hazardous and flammable gas clouds such as H2S. These systems must be designed for continuous operations during a gas cloud. The diving system is enclosed in pressurized and fire rated containers. The containers are kept safe through the use of gas protection systems and control over-pressurized spaces.
