WO won't move? (& other Qs)

[KNomad]

What does it take to get a Watch Officer to actually go outside when surfacing?

Also, how do I run decks awash w/o a mod?
Every time i try to dive a little the bridge clears.

Another, I've read about running w/o one deisel engine recharging the baterries?
How do I do this?

Thanks in advance.
