An electric propulsion drive system in which the propulsion generator supplies power to both the propulsion motor and ship service loads is referred to as what type of system?

Correct Answer: Option B — an integrated system

An integrated system, often referred to as a power station concept, utilizes the main propulsion generators to supply both the propulsion motors and the ship's service switchboard. This design optimizes fuel efficiency by allowing fewer prime movers to run at higher loads, distributing power based on total vessel demand.
