I think the first sentence is key, "Submersibles
will be assigned Class only after it has been demonstrated that their buoyancy
and their static and dynamic stability in in tact condition is adequate FOR THE
SERVICE INTENDED". Some of the lack of specificity is because they can't
conceive of every possible application. They do however have quite a few
specifics as you outlined. Some of the testing won't apply (ie fuel load)
and it's possible that a narrow scope of service might lower number of tests
required.<br clear="none">
