Berth the watch crew while submerged (O's in the conn, E's in the bunks).

I keep 1 good engineer, and one sensor oper in DC, and swap them out when they get fatigued. In emergencies when I have bulkhead damage I'll grab 2 engineers or anyone with high mech skills for DC, reverse for electrical repairs. Having an officer leading DC helps ALOT, but mind the skills- mech for mechanical repairs, elec for electrical repairs. Soon you'll get a DC bonus crewman, he doesn't need to be in the DC shop, but he needs to be alive.
