The solutions I have posted will always show the pressure at working
depth and the maximum allowable working pressure as being approximately
identical.  These are the final values when the solver arrives at a
solution, differing only by the discrete nature of the iterative process
(adding either 0.0001 m of shell thickness or 0.1 m of working depth on
each iteration, depending on the selected mode).  Every one of the
posted solutions meets the ABS requirements - some just don't meet your
desired working depth, or your desired shell thickness.
