Which of the following compressors would be used for a dead ship start-up of a ship's service diesel- generator on a motor ship?

🔍 Key Concepts

• Difference between starting air, service air, and topping air systems on motor ships • Purpose of a dead ship start and which systems are still available when the ship has no power • Which compressor is directly connected to the main and generator engine starting air bottles

💭 Think About

• When a ship is completely without power, which air system would still be usable or specifically intended to restore propulsion and electrical generation? • Which compressor is designed to supply high‑pressure air directly for engine starting, rather than for tools, controls, or general services? • Think about which compressor must be capable of building up the first charge of air to crank the diesel‑generator when no other systems are running.

✅ Before You Answer

• Verify which system provides high‑pressure air (usually around 20–30 bar or higher) to engine starting air manifolds • Check which compressors are normally driven by electric motors and which arrangement is intended for use when ship power is lost • Confirm which compressor is tied into the engine starting air bottles, not just general service or control air lines
