Hi Jon,
Here"s a link to a book "Guidebook for design of ASME section v111 pressure 
vessels".
http://books.google.co.nz/books?id=_8nVW5RMnjYC&pg=PA134&lpg=PA134&dq=understanding+external+pressure+loading&source=bl&ots=JC5mx8oWu0&sig=bBSOlRoPz51IkGOMNyOHhxG4cY0&hl=en&ei=03C9S_XtGZTUsQPPmOWrBA&sa=X&oi=book_result&ct=result&resnum=9&ved=0CBsQ6AEwCDgU#v=onepage&q&f=false
Don't know if it's relevant, but have a look.
