This paper presents material associated with assessing the effectiveness of a variety of condition monitoring approaches within the context of a predictive/preventative maintenance strategy. It promotes the concept that earlier thinking on the application of RCM may need to be assessed in the light of the growth of lower cost predictive maintenance and life forecasting technologies, and hence whether or not primary outcomes of tools such as FMECA need to be further skewed to embrace more fully the details and attributes of various life assessment possibilities. The application of RCM Turbo as an automated/semi-electronic diary approach to employing RCM is tested for relevant aspects such as the application of its criticality scores to assigning equipment criticality rankings within the maintenance system, thereby assisting the scheduling and prioritization of predictive maintenance tasks.
