Q

Which of the following is a disadvantage of utilizing a gas turbine versus a diesel engine for propulsion?

🔍 Key Concepts

• Power-to-weight ratio differences between gas turbines and diesel engines • Typical maintenance and repair requirements for gas turbines compared to diesels • Common vibration characteristics of gas turbines vs. diesel engines

💭 Think About

• Think about which type of engine is preferred in applications where weight and space are limited, like high-speed naval or aircraft uses. What does that suggest about its power-to-weight ratio? • Consider whether gas turbines usually require highly specialized maintenance and calibration. Would that more likely be available onboard any vessel or at dedicated shoreside facilities? • Recall which type of engine has large reciprocating parts (pistons, connecting rods) and which has mainly rotating components. How does that affect vibration levels?

✅ Before You Answer

• Before choosing, ask: Does a gas turbine really have a low, or a high, power-to-weight ratio? • Verify which engine type usually needs specialized shoreside support rather than simple onboard mechanical work. • Confirm which engine design naturally produces more vibration in normal operation — the reciprocating diesel or the rotating gas turbine.
