Oberon Class Submarine
On display at the Fremantle Maritime Museum.
2 x V16 diesels powering generators which charged 448 battery cell's to run electric motors for propulsion.
Three Interesting Submarine Facts:
1:
These motors suck their air from inside the sub [where the crew are], the motors can only be run when the sub is at, or near the surface, so air can be drawn into the submarine, either through an open hatch, or if near the surface, through a inlet snorkel. If the motors where running without an air supply from the surface, the hull would be sucked free of air, becoming a vacuum. The motors would eventually stall but the crew would suffocate.
2:
Of the 7 ballast tanks, 2 are used for diesel. As the fuel level decreases, water is pumped in to keep the tanks full. This prevents the tanks from failing due to pressure when submerged. The diesel floats on the water in the tanks. Any water mixed with the fuel is separated prior to being by the motors.
3:
The toilets are so small. sailors needed to drop their pants in the hallway, then reverse into the toilet, sit down and then close the door. This procedure was reversed when the job was done !!
