Re: [PSUBS-MAILIST] They're Just "Guidelines" !

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?

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?
