Continuous Online Monitoring as the Foundation of a Condition-Based Maintenance Strategy
The shift from Time-Based Maintenance towards Condition-Based Maintenance (CBM) is succinctly illustrated by the P-F curve below, showing the importance of detecting potential failure at the earliest time possible. In other words, extending the P-F interval gives us more options in deploying the optimal maintenance strategy to meet the business goals.
While improving reliability is a key goal for industries like Power, sustaining management support in the transition towards a Reliability-Centered Maintenance strategy is also contingent upon reducing the total cost of reliability. Often, older assets require additional investments in instrumentation to support continuous monitoring, which tends to run up initial costs of a CBM program. Hence, a pragmatic approach is about balancing or optimizing the total cost across the three maintenance strategies (predictive, preventive, reactive) throughout the reliability journey, as shown below:
Implementing this strategy is a matter of understanding where the gaps are in current maintenance processes, and subsequently, how much to invest in closing these gaps. The November 8th webinar on Asset Reliability Best Practices (Part 1) introduced the process framework (shown below) for deploying CBM in the Power industry. In our next webinar (scheduled for December 8th), we delve into the sub-process of “Monitoring System and Component Health”, which is perhaps the most important capability gap to be addressed.
The December 6th webinar will explain how the predictive capabilities of a CBM program typically evolves along a 4-stage maturity model. To learn more about this maturity model, along with industry examples, we encourage you to sign up for this informative session. Register for the webinar now!
