• The cylinder liner and piston rings of present large marine diesel engines are in severe lubricating condition with the trend of higher engine output. Sometimes their abnormal wear due to scuffing appears in the earlier stage of the voyage despite manufacturer's effort in the structural and metallurgical modification. In such situation many researchers are studying the method of the lubricating condition monitoring from viewpoint of Condition Based Maintenance (CBM). The purpose of this study is to establish the technique for wear condition monitoring of cylinder liner and piston rings based on liner vibration signals. This paper describes the results of preliminary test carried out in shop trial of a 2-stroke cycle engine, and examines the effectiveness of the monitoring method by the analysis of vibration data measured in the period of running-in of the engine.
