Scott, my pressure hull optimization software project has been
sitting idle on the back burner for some time now. Nevertheless,
some of the modules work, so I ran your numbers through the
spherical shell calculator. The results shown below are in
compliance with the most recent ABS rules, with no additional safety
factor added. I used your 6' dimension as the inner diameter, and
incremented shell thickness 0.0001 m at a time until the desired
working depth was reached. Executive summary: 0.0378 m (1.4882 in)
for A516 gr 70, and 0.0208 m (0.8189 in) for HY-80. Details below:<br>

Let me know if you want to run additional scenarios.<br>
