Scuttle valves: It is a generally accepted rule of thumb that most submarines
will have high pressure air for the ballast system. There is no need for a
Scuttle Valve. All that is needed is a valve that can be opened from the inside
that will let in high pressure air into the pressure vessel till it’s equal with the
out side. Then you will be able to open the hatch, I do have lots of
experience in submarines and it is not a normal procedure. It is mush
better to make a good dive plan and we in submarines do not just get
tossed into the water and drive around all willy nilly across the ocean floor.
This action would be a death trip waiting to happen. Next, the life support
system should be designed for a minimum of 72 hours for each person.
But in truth, if you get stuck on some thing you will probably die from
hypothermia before your life support is depleted.
Also, it should be considered impossible to escape from a submarine at
any depth deeper than 200 feet!
. As the pressure is increased in side the
sub so that it’s possible to open the hatch you will become over come by
Nitrogen Narcoses. So at that point you’ll be having a bad day but you may
not care. These are the facts, don’t get hung up on any thing down there.
It will probably be the last hang up you’ll ever have.
