The triton 3300/3 submarine

I have done over 220 dives as sub pilot and I am the repair tech for the sub.

The Submarine I was the pilot on and repair tech is the Triton Submarines 3300/3.  It is a 3-person sub that can go to 1,000 meters or 3,300 feet for 96 hours.  The sub has Main and Reserve Oxygen Tanks and Main and Reserve Air tanks.  Oxygen is being added to the cabin and there is a CO2 scrubber that removes the CO2.  There is no change in cabin pressure all the way to 1,000 meters.  There are 6 different ways to surface the sub and only three of them need power.
