In order to keep ship safety and to develop a high reliable marine engine, factors of marine engine troubles are analysed by the Principal Component Analysis Method. Analysed data are concerned with marine engine troubles resulted in sea accidents, marine automatic control device troubles and marine diesel engine cylinder troubles. It is proved that the P.C.A. method is adequate for the analysis of trouble phenomena. Main results are as follows; 1. Marine engine troubles are classified into five groups using principal factors interpreted as degrees of damage, mobility of machine and human factor. 2. Though it is hard to interpret principal components of automatic control device troubles because of low factor contribution, tree diagrams showing relation between many factors are obtained by proposed Quadrant Method. 3. Piston and cylinder cover troubles of diesel engine are expressed by two factors; one is the combination of engine size and cooling method and the other is designed pressure.
