Introduction

CBM is a planned maintenance approach where asset conditions are observed using real-time information, and maintenance is only carried out if required. Unlike other maintenance strategies, CBM avoids regular, unnecessary maintenance and minimizes production halts. Since potential failures are detected beforehand, CBM prolongs asset life, increases precision observation, and optimizes resource allocation.

It also leads to sustainability since it eliminates waste and preservation of resources. In this article, the author discusses CBM fundamentals, advantages, steps towards its utilization, and its impact on organizational asset management evolution across various industries. 

Condition-Based Maintenance: What exactly is it, and how does it work? 

CBM—Condition-Based Maintenance—is a workable strategy for performing maintenance based on an asset’s condition at any given time. CBM ensures that it approaches issues at the right time, minimizes maintenance, and enhances asset reliability, unlike conventional approaches that fixate on an aspect of whether it is required. 

Unlike preventive maintenance, in which operations are carried out based on set time intervals, and predictive maintenance, in which operations are carried out based on historical data, intrusive condition-based maintenance and monitoring (CBM) is real-time monitoring with specific corresponding immediate responses, which makes it efficient and effective. 

Benefits of Implementing CBM: 

• Eliminates the possibility of closing the business because of some complicated problem. 
• Minimize costs that may otherwise be incurred in performing unrequired repairs. 
• Reduces asset deterioration and hence maximizes the period of use by focusing on the condition of the particular asset. 
• Improves organizational functionality by acting promptly and providing accurate and timely maintenance. 
• Reduces risk by eliminating causes of major equipment breakdowns. 
• Great for streamlining resource distribution and assistance with more sound maintenance management decisions.

The advantages and limitations of condition-based maintenance 

Pros 

Avoid unnecessary maintenance by assessing problems through data to prevent disruptions hindering the work process. 

It reduces everyday maintenance expenses by eliminating the need for repair during an emergency and reducing the frequency of operation downtimes. 

Improves decision-making by prioritizing the assets that require attention in terms of maintenance, hence conserving resource wastage in spare part inventory. 

Prevents or reduces problems that, if not corrected on time, could lead to shortened asset life, ensuring efficient equipment utilization. 

Results in more calculable cycles or periods of maintenance contribute to the safety and effectiveness of work in the workplace due to the reduced series of equipment breakdowns. 

Cons 

It cannot be implemented within the first year since it involves large amounts of money, which must be spent on buying condition-monitoring equipment and installing it in various parts of an organization. 

The incorporation of sensors for monitoring and other related devices, particularly if they are in old systems, may require a change of assets. 

Requires highly skilled personnel for the maintenance department; hence, it may be costly for organizations with little experience. 

It may also prove costly in environments that can damage sensors and monitoring devices, thereby incurring more in replacements or maintenance. 

CBM heavily relies on real-time monitoring and, hence, on the effectiveness of monitoring devices, which may at times develop a fault and give erroneous information. 

Technical Considerations and Condition Monitoring Techniques 

Key Components of CBM

Vibration Analysis

Immersive technology sensor that measures variations in dynamic force levels of rotating equipment for signs such as imbalance, misalignment, bearing condition or looseness. This technique allows maintenance teams to foresee and solve possible failures before they occur, thus minimizing equipment breakdown time and improving equipment durability. 

Thermography

Uses infrared radiometric technology to measure the temperature profile of surfaces and identify areas of high temperature and or sudden/ gradual changes in temperature. Possible concerns include early detection of overheated parts, failure of the insulating system, overloaded circuits, or lack of oil in the moving gears so that necessary rectification can be made timely. 

Ultrasound Analysis

Uses high frequency sound analysis to diagnose issues that may not be detectable by standard human notions. This technique is useful in detecting centerline or mid-line air or gas leaks and diagnosing leakage in pumps associated with cavitation, electrical discharge concerns, and mechanical wear, which may not manifest fully. 

Oil Analysis

Used to diagnose the state of a lubricant, its degree of contamination, and the content of wear debris. It may predict potential problems with engines, gearboxes, or hydraulic systems, avoid expensive equipment failures, and detect the best time for lubrication to enhance performance. 

Acoustic Emission Monitoring

Records and measures acoustic signals generated by other materials in conditions of pressure, distortion, or rust. This non-destructive procedure helps engineers determine the real health status of some mechanical parts so that preventive measures can be taken before they fail catastrophically. 

Pressure and Flow Monitoring

Currently measures flow behavior in pipelines, pumps, or hydraulic systems on a constant basis. Fluctuations in pressures or flow rates can show signs of blockage, leakage, faulty valve, or an inefficient pump. Combating these anomalies makes it possible to achieve uniformity in the system and leads to energy savings. 

Data Collection and Analysis 

Condition-based maintenance is initiated by a data capture and analysis process, which involves capturing data from the destination using IoT-enabled sensors and systems to make a point data of the equipment performance. Integrated data gathering gathers data from multiple sources in one area and processes it much faster.

Accurate predictions of failures by pattern recognition, advanced analytics, AI integration, and quick comparisons between historical records improve the monitoring and predictability of outcomes. 

Setting Thresholds and Alarms 

Thresholds and alarms establish measurable limits above and below which a monitored variable does not usually vary, derived from historical experience and manufacturer specifications. Dynamic limits adjust these ranges as equipment ages or conditions affect it.

They work based on priorities, with alerts; accordingly, moreover, integrating with CMMS means linking the alerts with schedules or work orders for response according to the timeframe. It also leverages backup alarms and redundancy to ensure important notifications are not lost.

Role of CMMS-Based Software in Enhancing CBM 

Centralized Data Management 

Applying CMMS strongly improves CBM approaches as it offers an essential tool for perfect maintenance action management. ICM software attributes gather related information at different locations for easy tracking of the performance and maintenance history of the company’s assets. This centralization makes work easy to handle and results in increased efficiency. 

Interoperability with monitoring applications 

Another advantage of CMMS-based software is its compatibility with monitoring tools. Integrating IoT devices and sensors, CMMS collects actual data and sends it to the maintenance team to consistently monitor equipment status. This integration also enables interventions at the right time and the right decision-making. 

In relation to Automated Alerts and Notifications, the following is proposed: 

Thanks to modern solutions, such as CMMS software, reporting and analytical data contribute to improving maintenance activities. The system provides comprehensive reports on asset behaviors, maintenance operations, and periods of downtime, allowing organizations to detect patterns in performance, improve maintenance approaches and strategies, and facilitate timely, informed decisions. 

Offering better, more specific reporting and analytics 

As with other software, flexibility and scalability are major advantages the CMMS-based software offers. It offers the ability to customize the system for an organization’s unique needs. It allows businesses to easily expand the system as necessary to keep the maintenance management solution relevant and useful. 

Scalability and Customization 

Enhanced compliance and documentation arise because of the systematic documentation of maintenance activities, schedules, checks, and compliance measures documented in the CMMS software application. The information included in this documentation minimizes the chances of violating governing industry regulations and standards, successfully making an organization avoid prosecution. 

Improved Compliance and Documentation 

CMMS software facilitates improved compliance and documentation by maintaining comprehensive records of maintenance activities, inspections, and compliance requirements. This documentation supports adherence to industry regulations and standards, reducing non-compliance risk and associated penalties. 

Implementing CBM: A Step-by-Step Guide 

Assessing Asset Criticality 

Start with a list of essential assets that need protection due to the organization’s operations, production capability, and safety. Continue to concentrate on those parts of the equipment that are most prone to failure or exert the most impact on operational efficiency, thus keeping CBM resources consistent. 

Choose Proper Monitoring Instruments 

Select the most appropriate condition-monitoring devices, including the type of CM, which may be vibration analysis, thermal imaging, or oil analysis, depending on the assets in question. The selected tools should be interoperable with current systems, and we must collect accurate and timely data for analysis. 

Setting up Pre–Interventional Checks 

For each asset, capture beginning performance data to identify normal operating parameters. These baselines are used in calculating anomalies, which can be used to easily recognize ‘issues’ in a solution or environment and avoid false positive alarms. 

Training Personnel 

Ensure that the maintenance teams have the required awareness of monitoring tool control, result analysis, and alarm management. Up-to-date training prepares staff to embrace changes in technology and best practice approaches to boosting CBM’s success. 

Including CBM in Maintenance Management Systems 

Easily embed CBM processes within your maintenance management system, including a computerized maintenance management system (CMMS). The required work orders should incorporate a notification system and an automatic data collection system to make work easier and inform the parties concerned when maintenance is due.

FAQ’s

What do we understand by CBM?

CBM is a maintenance strategy that focuses on ascertaining the real status of the asset in order to know whether it requires maintenance or not. How it works: it receives real time data from sensors, inspection and predictive maintenance analysis to detect problems before becoming critical and causing equipment failure.

In what way is CBM useful in increasing the lifespan of assets?

CBM prolongs the working life of the asset by conducting maintenance when it is necessary, thereby minimizing the wear and tear arising from other operations which might be considered redundant. What it does is that it enables one to avoid extensive damage while at the same time maintaining the assets for an extended time.

Notably, what technologies are usually applied by fluid mechanics in CBM?

CBM utilizes IoT sensors, vibration, thermal, oil, and different analysis techniques like AI and machines learning to collect and study data about the asset’s conditions.

What kind of assets receive the most benefit from CBM?

Corrosion in the operations of machinery, pumps, HVAC systems, heavy equipment, vehicles, and compressors are ideal fits for CBM. These are also usually some of the most crucial or costly assets to repair and maintain, therefore establishing preventative strategies as affordable solutions.

What is the difference between CBM and preventive maintenance?

However, whereas preventive maintenance involves an idea schedule, CBM is based on the actual condition of the assets. Finally, CBM eliminates numerous non-value-added maintenance actions while preventive maintenance might result in over maintenance and, at other extremes under-maintenance.

CBM implementation will be successful if the following points are considered:

Success indicators of CBM are identified as MTBF, MTTR, percentage of asset downtime, cost of maintenance, and the ROI. Because of these metrics, it becomes possible to evaluate the CBM effect on all the extracted asset performance indicators and operative efficiency rates.
