Abstract
So far many papers on the results of the failure and the maintenance of the Marine Engine Systems have been reported. Among them, the SR-85 report which was made a thorough investigation of the marine use mechanical devices by the Shipbuilding Research Association of Japan for a period of four years from 1966 to 1969, is one of the most important results in the viewpoint of the Reliability and Maintenability (R&M) of ships. After that, many authors including T. Hashimoto, et al., have investigated the statistical characteristics of the R & M of the marine engine systems.
In the present article, the important results obtained till now are summarized and on the basis of the results, the statistical trends are considered. Then, the statistical characteristics of the R & M of the main diesel engine in the latter half of 1970's are made newly clear by comparing the results in the latter half of 1960's.
