Brian,
I suppose that would be one way
of doing it. But you might try calling first to see if they believe they
have jurisdiction or requirements for submersible operation. Perhaps more
information would be helpful regarding your definition of "human
occupancy". You don't need certification from anyone if you're just using
the sub for yourself or taking passengers for free. If you want paying
passengers, then I think you'll need Coast Guard certification for the vessel
and a "captain" certification from them. It's been a long time since I had
my boat, but I believe those were the conditions for a vessel that was "for
hire". Of course, that only applies to waterways in which the Coast Guard
has jurisdiction. You don't need ABS certification unless you are looking
for insurance on the vessel. In that case, I assume the insurance company
would dictate who they required to perform the inspection for
certification.
I don't have a definitive
answer for you Brian. Just recalling some of the issues I've heard about
in the past.

Jon,
So you just
motor up to the coast guard dock with your 50' X 8' dia
concrete sub and say " I need my sticker" ? I'm
sure they would have no idea what they were looking at. But I
guess if you had all of your floatation devices, flares, anchor, radio, they
would pass you. What do you think?

Hi
Brian,
Wouldn't the coast guard be
the guiding authority?
Jon
I have a hypothetical question concerning pressure vessels for human
occupancy. What if the material that is being used is not addressed
in the "guidelines" in the PVHO handbook? The material I'm thinking
of is concrete, would certification by an engineer as to the strength of
the material suffice ?
Also say a pressure vessel for human occupancy was built and say that
this pressure vessel was only going to be lowered in and out of the water
with a crane. If the pressure vessel was certified by a qualified
engineer would that be different than Lloyds of London or the ABS
certifying a submarine? Doug Farrow, any thoughts on this?
