The basis of all approaches to improving reliable marine engines is to analyze the field data of troubles and failures on marine engines. To this end, a data bank system is developed at Ship Research Institute. The data bank system contains data on ships and their engine failures and troubles. The total number of ships dealt with is 1029 vessel × year. The details of the data bank are described in this paper.<BR>Two examples of application of the data bank are stated here. One of them is factor analysis of diesel engine failures by the Irincipal Component Analysis Method. Especially, detecting methods of abnormal states and initial judgments by operators are carefully analyzed as failure factors. The other is a failure map as an engine trouble diagnostic system.
