RE: [PSUBS-MAILIST] STANAG NATO standard flange
Carsten,
Yes there is a standard for the flat section surrounding the hatch on the
stranded sub. I have it buried someplace but can't find it. Think we have
discussed it here years ago and one of the issues was that it was too big
for the typical PSUB. In your case it would be applicable.
Have seeing the web framing below the mating surface and above the hull, it
is substantial.

As scarce as the truth is, the supply has always been in excess of the
demand.

Year Jay I know, but is there a standard in the outer and inner diameter of
the smooth flat section?
Or build everyone to Busby page..
If the rescue vessel dry the camber the outside pressure press the rescue
vessel against the sub.
In 500 meter deep and with a diameter of the skirt of somewhat around 1,5 m
the pressure will
be somewhat around 900 ts of water pressure force against the hull. So there
must
be something like a retainer ring below the smooth flat section to take that
force.
