Jon,
I went to the
Coast Guard web site and checked out some of the regs. They pretty much
cover every possibility, they don't really address subs as such, but they do
talk about diving operations, mainly correct signal lights and locations
of dive sites. They do mention Lloyds and ABS as referring to them as a
certifying agency and that they recognize them.

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?
