Destroyer Engineered Operating Cycle (DDEOC), System Maintenance Analysis DDG-37 Class, Salt Water Circulating System SMA 37-106-256, Review of Experience.

摘要

This Review of Experience (ROE) documents the historical maintenance experience for the DDG-37 Class Salt Water Circulating system, presents an analysis of the problems encountered, and recommends actions to improve system material condition. The following are among the major findings and conclusions resulting from the ROE for the Salt Water Circulating System: Comprehensive overhaul will be necessary for the main salt water circulating pump turbine and auxiliary circulating pumps during baseline overhaul; With the exception of the auxiliary circulating pumps, the system components will require restorative maintenance during the operating cycle but not at fixed intervals. The auxiliary circulating pumps should be overhauled at five-year intervals, and all other components should be maintained by using a 'fix-when-fail' maintenance philosophy; An on-condition maintenance philosophy is not appropriate for components of this system; and Reliable operation of the Salt Water Circulating System can be expected during the Engineered Operating Cycle if several recommended changes are implemented.
