I know virtually nothing about ships, but don’t those big ones run giant diesel engines? Which means a power interruption would not affect the engine, but would affect the steering and control of the engines?
It’s not like they have a stop/start feature like on new cars.
Generally ships, like houses or anything else have interior/exterior lighting on a separate circuit. Likewise navigation, and electronics should be on their own circuits...
They still communicate with the engine room engineering spaces as bridge controls are mostly "fly by wire"

Television and radio are most effective when people question little and think even less.
