摘要

In Japan, The SRIC database system of third generation has became a useful system included over 114000 field data about the failure of ship equipment pass the long time investigation. This database system has never been carried out in other countries. And SRIC is a relational database system constructed by the some data tables and many useful functions. It become clear that the average failure rate of the whole of ship equipment was 7.2 [case/100hr.] and the work for the repair was 5.0 [man*hr.] through the statistical analysis by SRIC. And, it is noticed that the failure ratio of miscellaneous equipment is about 43 [%]. The average failure rate is changing with same level. However, the work for repair was increasing rate from the middle of the 90s. The actual conditions for the reliability of the ship equipment gradually became clear, but the long term approach of the raise in reliability is necessary in the future. This paper reports the latest results of the statistical analysis and the multivariate analysis about the main engine system by using the information of SRIC. As a result of the cluster analysis, the reliability of the main engine system and its characteristics became clear.
