Question 571Electricity & Electronics - Assistant Engineer

The correct answer is C) excellent maneuverability. The key advantage of a diesel-electric propulsion plant is its excellent maneuverability. In a diesel-electric system, the diesel engines are coupled to generators that supply power to electric motors, which then drive the propellers. This arrangement allows for precise and responsive control of the propulsion, enabling the vessel to maneuver with great agility and precision, which is crucial for Coast Guard operations. The other options are not the primary advantages of a diesel-electric propulsion plant. While it may have lower maintenance requirements and fuel consumption compared to other propulsion systems, these are not the main reasons for its use. The cost and weight of the system can also vary depending on the specific application, so it is not a universal advantage.
