RE: [PSUBS-MAILIST] Viewport design

[Alec Smyth <Asmyth@changepoint.com>]

I can think of 2 options:

 

a) Locate a copy of the book "Acrylic Plastic Viewports" by Jerry Stachiw (see PSUBS references). Unfortunately this is next to impossible. Else you can go to Jerry's web page, www.hydroports.com, and order from a ton of reports. I have no idea what the cost of this is, although I'm sure the information is top notch.

 

b) Go to the ASME web page and buy the "PVHO" publication (Pressure Vessels for Human Occupancy). It costs a hundred something bucks, but its worth every penny. I've spent money on every conceivable sub-related thing, but these have to be the most worthwhile bucks of the lot. Its pretty much a viewport cook-book, based largely on Stachiw's research.

 

In either case, you'll then have to either make the ports yourself of have someone make them for you. Please, only use someone who makes viewports for subs. This is one area where the end product might look great but have hidden problems (e.g., incorrect material, improper annealing, etc.)
