🔍 Key Concepts

• Large, low-speed, direct-reversing diesel engines used for main propulsion on big ships • How starting energy is delivered to turn a very heavy engine from rest • Practical limits of electric, hydraulic, and air systems as engine size and starting torque increase

💭 Think About

• Think about which system can store and release a very large amount of energy quickly to crank a massive slow-speed engine • Consider which starting method is standard on large ocean‑going ships with low‑speed main engines • Ask yourself: for very large bore, low‑speed diesels, which method is most common in real-world ship practice, rather than what is possible in theory

✅ Before You Answer

• Compare the torque and power required to start a large low‑speed main engine versus what typical electric starters can provide • Consider how starting air systems are arranged on large ships (air receivers, starting valves, control air) and what they are sized to do • Verify whether hydraulic starting is usually reserved for smaller engines (e.g., emergency generators, lifeboat engines) rather than the largest main propulsion units
