The definitive equipment for surface-supplied diving is the breathing apparatus which is supplied with primary breathing gas from the surface via a hose, which is usually part of a diver's umbilical connecting the surface supply systems with the diver, sometimes directly, otherwise via a bell umbilical and bell panel.
NEDU began a project to modernize Stillson's MK V surface supplied diving system which had been in service since 1916 in the early 1970s, and developed, tested, and certified the replacement Mark 12 Surface Supplied Diving System which was taken into service in 1985, and eventually its replacement the Mark 21/ Superlight 17 in the 1970s and ...
Surface-supplied mixed gas diving, using helium based, nitrox, or trimix breathing gases. Usually using lightweight demand helmets, sometimes with helium reclaim systems. Airline or Hookah diving. "Compressor diving" - a rudimentary form of surface-supplied diving used in the Philippines by artisanal fishermen. Recreational forms like snuba.
Diving support equipment is the equipment used to facilitate a diving operation. It is either not taken into the water during the dive, such as the gas panel and compressor, or is not integral to the actual diving, being there to make the dive easier or safer, such as a surface decompression chamber.
Surface supplied commercial diving equipment on display at a trade show. Commercial diving may be considered an application of professional diving where the diver engages in underwater work for industrial, construction, engineering, maintenance or other commercial purposes which are similar to work done out of the water, and where the diving is usually secondary to the work.
The KM-37 diving system supports manned diving to depths of 190 feet (58 m) on surfaced-supplied air. A fly-away mixed gas system can be used to enable the support of diving to a maximum depth of 300 feet (91 m). [8] The MK20 MOD0 diving system allows surface-supplied diving to a depth of 60 feet (18 m) with lighter equipment. [8]
