Q

Which of the following is a disadvantage of electric drive propulsion systems?

🔍 Key Concepts

• Electric drive propulsion systems combine prime movers (like diesel engines or gas turbines) with generators and electric motors. • Think about what counts as an advantage (flexibility, control, power sharing) versus what adds extra complexity or equipment. • Compare mechanical drive (engine to shaft directly) versus electric drive (engine → generator → motor → shaft).

💭 Think About

• Which option describes something you could only say about the electric system that makes it more complicated or costly than a simple mechanical shaft line? • Look for the choice that adds an extra stage or extra machinery compared with a direct-drive system. • Which options clearly sound like benefits (more flexible, more controllable, more ways to route power), and which one sounds like something you must add or accept as a trade‑off?

✅ Before You Answer

• Identify which items are clearly benefits of electric propulsion (flexible machinery location, easy control, power sharing). • Ask yourself: in an electric system, do you need both power generation equipment and propulsion motors, or can you skip one of them? • Before choosing, separate the answer choices into two lists: items that simplify the ship versus items that increase equipment count and complexity.
