<DIV><BR clear=none>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><BR clear=none><BR clear=none>On 12/5/2013 4:08
