Layout and Operation of Equipment
1.2.1 On surface, the gas enters the Reprocessing Unit, where oxygen is made up to the
correct mix. The gas is then passed to an Electric Gas Booster where the pressure is increased
prior to returning to the Reprocessing Unit. It is then scrubbed to remove CO 2 and other
impurities before being passed to the Volume Tank for storage and eventual re-supply to the
conventional gas supply system. Thus, gas is passed via a bell umbilical to the bell gas supply
manifold and then to the diver’s demand regulator.
1.2.2 Addition of an optional second gas booster will allow 100% redundancy to allow
continued operation during maintenance. Similarly two scrubber canisters are provided either of
which can be replenished while a dive continues.
