Re: support vessels
Presumably, the weather limitation has to do with the management of
diver umbilicals. No sub, ROV, or AUV has the dexterity or ability on
site as divers. Whether you are recovering divers via a stage, or
using a PTC/DDC for sat divers, I can imagine the transfer process gets
pretty hairy with a sea running.

It's supposed to be in like 250 feet of water, and they keep having to delay because of the weather. I'm guessing this is due to the requirements of the surface vessels rather than the zubmersibles. There are the ships from which they operate the ROV, and the ones dragging sonar instruments, and so on.

Wouldn't it be great to have undewater operations, including this kind but also research and exploration ones, supported by really big submarines? A navy nuclear sub has all those torpedo and missile-launcher tubes which could launch smaller vessels -- all kinds of sensing equipment -- communications -- the ability to hang around underwater a really long time. Why don't they do this? This isn't really a P-Subs issue, as few of us have that kind of money, but hey.
