[PSUBS-MAILIST] O2

[Sean T. Stevenson via Personal_Submersibles]

Nothing wrong with internal tanks as long as you can prove by calculation that the unintended release of the contents of any single cylinder (provided they are individually valved - hard plumbed manifolded cylinders where a single failure would empty them all would need to be considered together as one) will not raise the pressure of the occupied space by more than 1 atm.

Through hull shouldn't be a big deal either. Drill larger if necessary, and use a stainless insert.

My original design in E3000 was to have external O2 supply but I prefer internal.  I messed up in two ways.  First off I provided a steel penetrator opening for O2.  The other screw up is when I built the new body I completely neglected access to change out the tank.  So I am going with internal tanks unless someone can talk me out of it.
