Tanks for Air Independent Propulsion  [ Return towards  Liquid oxygen storage  ]

Compact cryogenic system for AIP submarines, for increased endurance while diving

These tanks are used to store the liquid oxygen required to propel the submarine when diving and to provide breathing air for the crew.

The system comprises a cryogenic tank and circuits for distributing oxygen to the different functions.
Storage volumes are tailored to needs which can vary between one m3 and some hundred m3.
The system adjusts its distribution as a function of the needs of the installed AIP (Direct combustion in pure oxygen, Powering a reformer, Fuel cell) and can deliver low pressure or high pressure gas flow rates, or a combination of the two. The on-board oxygen supply line is tailored to the size of the crew.

Key benefits

  • Good thermal efficiency: no need for sea draining
  • Good resistance to military impacts specified up to 15 g, in compliance with weight requirements
  • Management of safety functions in a confined environment and in a severe marine environment
  • Quality of oxygen for crew and PAC technology

Principle technical characteristics

  • Materials compatible with Oxygen, with cryogenic temperatures and with the marine environment
  • Components qualified in environmental resistance: impacts, vibrations, platform movements, CEM, saline surroundings, climatic cycles, fire
