In order to determine the feasibility of employing a vibration data acquisition and analysis system in a shipboard preventive maintenance program, the Maritime Administration undertook a one-year project aboard two cargo liners. Utilizing vibration analysis techniques developed for industrial use, a program of periodic measurements of engine room rotating machinery was instituted. Vibration velocity measurements were recorded by portable battery powered instruments. Biweekly readings were recorded, plotted and compared by the ships engineers for indications of developing trends and maintenance/overhaul decisions. The accumulated data were reviewed in detail and specified recommendations for more frequent checks of equipment developing failure trends and maintenance actions warranted were provided to the ships Chief Engineer. Conclusions reached as a result of the project are discussed, as well as current engineering underway to utilize the output from this experience, along with a deviation method of preventive maintenance scheduling, for the first shipboard application of a computer aboard a ship of the subsidized fleet.
