I am not an expert on repair or damage control, but I've goofed around with some of the relevant files, so I can make some educated guesses.

First, hull damage is not repairable at sea (you probably knew that already).

Second, the compartments and subsystems have sections in the **.upc files, which define characteristics of this sort. High levels of damage would likely require higher levels of crew skill to repair, as well as greater lengths of time, and may not be possible as a practical matter.

Btw, the same mechanics apply to your human crewmen. Minor wounds will probably heal ok, more serious wounds might require a medic with high skill, if such is even possible.

Some repair times (or heal times) may be such that even a 90 day patrol would not be enough, making them, in effect, beyond repair.

I don't really know much about compartment flooding, pumps and those matters. Usually, my boat is either in good condition, or sunk.
