I'd need to check with an engineer, but I don't think the generators
used to power the main engines are the same as those used for "hotel"
services.

It varies from ship to ship, soem or the ones I am familiar with use DC
generators to drive the electric motors attached to the screws, others
use huge ac sets todo the same. The ac ones use the same generators for
ships service, which causes all kinds of problems for some scientific
gear.

All the ships I worked on and the ones at anchor close to where I work
shut down the main engines (the ac powered ones I'm not 100 percent sure
never sailed on one) when at anchor
