This paper presents the methodology and research results of monitoring of compressed air starting system of 3AL25/30 engine placed in Maritime Engineering Faculty of Gdynia Maritime University. Research was carried out using a set of acoustic emission Vallen System. Analysis of recorded parameters revealed leakage in the installation – damage of one of the valves. The test results indicate that the AE method can be useful for monitoring the technical condition of pressure systems of engines and devices in a ship's engine room during normal operation as an on-line system.
