The maintenance strategy was improved from the Break-down maintenance strategy, which is only for broken-down equipment, to the Preventive maintenance strategy. The Proactive maintenance strategy involves doing maintenance when data and sensors indicate it is needed, rather than after the equipment has broken down. The ROK Navy may want to adopt Predictive maintenance, which includes both Preventive and Condition-based maintenance strategies, in the future. By this study, I predict the remaining useful life of the ships equipment and obtain real-time descriptive data by fast Fourier transform. At-risk technologies identified by Predictive maintenance should be added to the naval ship upgrade plan. We should plan to train new experts in Predictive maintenance, especially vibration analysis, as soon as possible.
