🔍 Key Concepts

• Low-speed diesel main propulsion characteristics (RPM range, torque, starting limitations) • How minimum safe operating speed of a large slow-speed diesel affects ship maneuvering • Basic comparison of fuel efficiency and gearing between low-speed diesels and steam plants

💭 Think About

• Which option describes something that is inherent to how low-speed diesels operate, not something that can easily be changed by design? • Think about maneuvering in confined waters or approaching a pier: which limitation in the answers would make that situation more difficult with a low-speed diesel compared to steam? • For each choice, ask: Is this usually an advantage or a disadvantage of low-speed diesels versus steam plants in real-world shipping practice?

✅ Before You Answer

• Verify which system (diesel vs. steam) is generally known for better fuel economy in commercial shipping • Consider whether low-speed diesels normally require reduction gearing or can be directly coupled to the propeller • Check which option would directly restrict the vessel’s ability to run at very low speeds while still keeping the main engine safely in operation

Question 1 of 20

One major disadvantage of a low-speed diesel as compared to a steam main-propulsion system is __________.

the low efficiency of the system when a controllable pitch propeller is used

a minimum speed for the engines that limits the minimum speed of the vessel

the extra weight required for the diesel reduction gearing

the higher fuel consumption per SHP
