[PSUBS-MAILIST] Skadoc Battery Pod

[James Frankland via Personal_Submersibles]

Thanks Guys.
Its just a simple faced flange with an O ring seal.  There is no step.
Agreed, the clamps are a bit over the top, but i like heavy duty.

There will be a vent somewhere.  Probably a swagelok pipe into the hull,
with a valve for diving.  Thats all there is on Jodie B, just a tube into
the hull with a cap you screw on for diving.   Either that or a OP valve.

Im not 100% sure how to put the power through into the hull actually.
Options are:

1. Weld on penetrators like the K.
2. Blue Globe.
3. Swagelok pipework through into the hull with cabling inside running
through a ball valve.  In the event of a battery pod flood, pull the cables
off and shut the valve.
4. Leave all the High Power cabling outside the hull and Blue Globe them
direct to the motors.  Only low power relay connections would then be
required.  I like this idea, but it wont work with the Engine generator
inside.

anyway, just thinking aloud now..
