8.3 External compressed air system
The design of the starting air system is partly determined by classification regulations. Most
classification societies require that the total capacity is divided into two equally sized starting
air receivers and starting air compressors. The requirements concerning multiple engine
installations can be subject to special consideration by the classification society.
The starting air pipes should always be slightly inclined and equipped with manual or automatic
draining at the lowest points.
Instrument air to safety and control devices must be treated in an air dryer.
