Most submersibles require a selection of support equipment in order to operate. This equipment includes:

A. A high pressure air compressor with a high quality filtration system which is used to charge the high pressure main and reserve air banks aboard the submersible. In some cases this compressor can act as a dive compressor as well. For a Triton submersible a 5 standard cubic foot per minute unit at 3000 pounds per square inch (140 liters per minute at 200 bar) will suffice. The HP air supply connector will be installed on a remote, dual purpose charge panel near the sub and equipped with a dust cap and isolated with a quarter turn ball-valve with black handle.

B. Battery chargers. Four battery chargers powered from the yacht's main electrical system. The input voltage/frequency would be matched to the yacht's electrical system and the output voltage would be dependant on the sub model. While the chargers can be remote, a charge panel must be close to the sub and will have two polarity protected, current specific, water-tight connectors for the high voltage side and two more connectors for the low voltage side as well. The physical dimensions of the connectors must be different to prevent crossing.

C. High pressure oxygen gas booster pump. The pump is used to transfer oxygen from the high pressure oxygen storage bank aboard the yacht to the submersible, or from a storage bank ashore to the storage bank on the yacht and may be either electrically or pneumatically powered. The charge panel will also have a high pressure oxygen supply connector equipped with a dust cap and isolated by a needle valve with a green handle.

D. High pressure oxygen storage cylinders. The number and size of cylinders is dictated by the mission profile of the submersible. A typical Triton installation would include six 'K' sized bottles. An oxygen generating air fractionation system could also be used to supply oxygen to a smaller group of bottles.

E. Vacuum pump with dry nitrogen back-fill system. The system is used to introduce a nitrogen atmosphere into the external electrical junction bottles of the submarine. The enclosure must be vacuum tested after maintenance to insure there is no leakage and then back filled with dry nitrogen.
