Contrary to the days of traditional, time-based maintenance, today, the spotlight is on a dynamic and proactive method that adapts to the actual condition of equipment — commonly known as conditional maintenance.
The essence of condition-based maintenance (CBM) lies in its ability to leverage real-time asset data and predictive analytics. This data-driven approach allows organizations to move from a reactive stance towards a more anticipatory and strategic approach. This shift from a fix-when-broken mentality to a predict-and-prevent mindset is at the core of the transformative power of conditional maintenance.
In this blog post, we delve into the significance and benefits of conditional maintenance, exploring how this paradigm shift is not only enhancing operational efficiency but also establishing a new era of cost-effectiveness and sustainability. Let’s dive in!
What is Conditional Maintenance?
Conditional maintenance is a proactive strategy that schedules maintenance tasks based on an asset’s condition or performance rather than adhering to a fixed time interval. The goal is to optimize resource utilization by conducting maintenance when it is most needed. This maintenance approach helps in minimizing unnecessary downtime and extending equipment lifespan.
Traditional time-based maintenance follows a calendar schedule regardless of an asset’s actual condition. This approach mainly results in equipment being taken offline, irrespective of its actual condition, leading to unnecessary disruptions in operations. According to an ARC Advisory Group’s Enterprise Asset Management and Field Service Management Market Study, around 30% of preventive maintenance is too frequent.
Conditional maintenance, on the other hand, allows organizations to schedule interventions precisely when they are needed. It relies on real-time data and monitoring systems. Sensors, predictive analytics, and monitoring tools like predictive maintenance continuously assess the health and performance of equipment. Maintenance activities are triggered when specific predefined thresholds or indicators are met.

What is an Example of Condition Monitoring Maintenance?
Condition-based maintenance involves utilizing vibration analysis to monitor rotating machinery in industrial settings, such as pumps, motors, and turbines. These machines typically exhibit specific vibration patterns when in good condition. However, as components wear or faults develop, these patterns change. Vibration monitoring sensors in condition monitoring systems continuously collect and analyze these vibrations.
For a condition-based maintenance example, consider a pump in a manufacturing facility with established baseline vibration levels during regular operation. If the vibration levels surpass predetermined thresholds or deviate from the established baseline, it may indicate issues like misalignment, imbalance, or bearing wear. In response, the condition monitoring system can generate a maintenance alert or work order.
Implementing condition based maintenance strategy through vibration analysis allows organizations to schedule maintenance precisely when needed. Ultimately optimizing equipment performance, preventing unexpected failures, and extending the lifespan of critical machinery.
What is the Process of Condition Maintenance?
On-condition maintenance is focused on addressing equipment or asset issues based on their real-time condition, as determined through continuous monitoring and assessment. This maintenance approach proves particularly advantageous in minimizing unnecessary maintenance and optimizing resource utilization by addressing issues.
The on-condition maintenance process involves the following steps for enhanced clarity:
- Asset Monitoring and Data Collection: First off, maintenance managers employ various sensors, monitoring devices, and data collection tools to gather information on equipment conditions continually. They measure parameters like temperature, vibration, fluid levels, pressure analysis, and other relevant indicators based on the equipment type.
- Establishing Baselines and Thresholds: Now, facility managers set baseline performance levels and normal operating conditions for the equipment. They define acceptable thresholds or limits for each monitored parameter, which act as triggers for maintenance actions when exceeded.
- Continuous Analysis: Expert maintenance personnel use asset management solutions to view advanced analytics and other monitoring techniques for ongoing analysis. With the help of digital software, they compare real-time data to established baselines and thresholds to identify deviations or anomalies.
- Condition Assessment:Facility maintenance teams assess the equipment’s condition based on the analysis. Determine if the current state indicates regular operation, potential issues, or the need for maintenance.
- Maintenance Trigger: If the equipment’s condition falls outside acceptable parameters, maintenance managers initiate maintenance activities. This may involve generating work orders,scheduling inspections, or starting specific maintenance tasks.
- Scheduled Maintenance:Maintenance technicians perform maintenance activities as required, addressing identified issues or potential problems. This could include repairs, replacements, or adjustments.
- Feedback Loop:After completing maintenance, maintenance managers update the monitoring system with the latest information. Ideally, they adjust baseline conditions or thresholds based on feedback from maintenance activities to enhance the accuracy of future assessments.
