Question 26General Subjects - Assistant Engineer

The correct answer is D) Emergency air compressor. For a dead ship start-up of a ship's service diesel-generator, the emergency air compressor would be used. This is because the emergency air compressor is specifically designed to provide the high-pressure air needed to start the diesel-generator when the main ship's service systems are not operational. The other compressors, such as the ship's service air compressor, starting air compressor, and topping air compressor, are not typically designed for this specific purpose and may not be able to generate the necessary air pressure for a dead ship start-up.
