An overview of the use of compressed air on ships, including the different purposes it serves, the various types of air compressors used, and the key components and mountings of the air reservoirs. It covers the high-pressure air used for main engine starting, as well as the lower-pressure service air used for a variety of applications such as starting auxiliary engines, charging water systems, and operating pneumatic tools. The document also discusses the importance of pressure reduction valves, compensation rings, and safety features like fusible plugs and relief valves. This information would be useful for students studying marine engineering, ship operations, or related fields to understand the critical role of compressed air systems in the functioning of a ship.

Compressed air on ships is used for different purposes. High- pressure air of 30 bar is mainly used for the main engine starting. This high-pressure air is reduced to lower working pressures through pressure reduction valves and is used for other important purposes. The air at reduced pressures of 7-8 bar is used as service air for a number of applications. Some of these include starting of Auxiliary Engines, Emergency Generators, Charging of freshwater and drinking water hydrophores, blowing the fog horn, spring air for exhaust valves of the Main Engine, dry washing of Main Engine turbochargers, for use in sewage treatment plants for aerobic sewage breakdowns, soot blowing of boilers, pneumatic pumps for oil transfers and many more applications such as service air for the use of cleaning, painting operations, chipping and operation of pneumatic tools such as grinders, chisels etc.
