Preventive Maintenance Solutions for Long-Term Asset Performance
Preventive Maintenance (PM) is a proactive strategy in maintenance to avoid catching you off-guard with unplanned downtime from unexpected equipment failure. By carefully planning equipment maintenance schedules in advance, the industries can gain strategic benefits in managing the assets and optimise their operational life.
Preventive maintenance aims at identifying and resolving potential equipment issues efficiently before they escalate and cause a crash. PM focuses more on planned routine inspections, maintenance, servicing, and repairs to ensure efficient and hassle-free operations with enhanced equipment life.
Preventive Maintenance (PM) approach is particularly beneficial in asset-intensive industries such as manufacturing, automobile, oil and gas, and various other industries. Efficient asset management is of paramount importance in these critical industries where an unexpected equipment failure can lead to catastrophic losses and safety compromises.
An effective PM maintenance strategy stresses more on planning and executing equipment servicing before faults arise. A robust preventive maintenance program also depends on tracking the previous inspections, interventions, and service histories.
Considering the complex demands and challenges of managing maintenance schedules across numerous pieces of equipment, many organisations embrace advanced preventive maintenance software platforms to redefine, monitor, and coordinate these schedules. Lets figure out more about preventive maintenance.
What is Preventive Maintenance?
From a technical standpoint, Preventive Maintenance is a planned, proactive maintenance strategy rather than a preventive or reactive approach. PM is the regular and routine inspection, repairing and upkeep of equipment and assets to significantly reduce the chances of unexpected breakdowns, involving maintenance activities at planned intervals to keep these machines working efficiently at optimal condition, extending their life and avoiding costly repairs.
Preventive Maintenance is an imperative technique in asset condition monitoring, systematically monitoring the condition of assets to understand and detect potential issues before they turn into costly failures. By adopting advanced technologies and data-oriented methods, preventive maintenance ensures asset integrity and reliability.
Preventive maintenance picks up the first signs of distress, wear, misalignment, vibration or equipment fatigue, enabling corrective actions before they develop into critical failures. One other important benefit of a proper preventive maintenance program is that through regular servicing, the energy efficiency of systems is enhanced, and the system runs within defined tolerances. It also supports safety compliance and prevents secondary damage to associated systems.
In an overall view, PM also contributes to efficient industrial facility upkeep, which includes routine HVAC, electrical networks, and lighting systems checks. Modern maintenance teams make use of technologies such as automation, Internet of Things (IoT), data analytics, and Artificial Intelligence to optimise operations, predict defects, and prevent operational downtime or unforeseen repairs.
What are the Types of Preventive Maintenance?
Preventive Maintenance modules and programs are built on the idea of proactive and planned maintenance, focusing on streamlining operations within organisations. There are generally five types of Preventive maintenance:
Usage-Based Maintenance (UBM)
Usage-based maintenance schedules are chosen based on how often and how much an asset is used and the condition in which it operates. Factors such as operating hours, load cycles, and environmental exposure determine the maintenance schedule and frequency.
Time-Based Maintenance
Time-Based Maintenance is done at set intervals, for instance, daily, weekly, or monthly, and not based on the equipment usage. These schedules depend on manufacturer guidelines and operational best practices. Critical machinery may be inspected or serviced weekly to ensure consistent performance and avoid serious equipment damage.
Condition-Based Maintenance (CBM)
Condition-based maintenance relies greatly on real-time monitoring of equipment health to decide on the maintenance schedule. By closely following key aspects like vibration, temperature, pressure and wear, the maintenance team can assess the equipment's health and act only when these key parameters show signs of faults.
Prescriptive Maintenance
Prescriptive maintenance uses a bit more advanced analytics, machine learning and AI to predict potential failures and recommend corrective actions. This is ideal for maintenance teams to understand and get a hold of the type of action needed to be taken at what time and the likely outcome. This maintenance strategy enables informed decisions and much more optimised maintenance tactics.
Predictive Maintenance (PdM)
It is a proactive approach to maintenance strategy that uses actual data collected using condition monitoring tools and sensors to predict when equipment is likely to fail, so maintenance and corrections can be performed just before a breakdown occurs. The main advantage of predictive maintenance is that it reduces unwanted maintenance while also preventing sudden failures.
Benefits of Preventive Maintenance
Preventive maintenance provides numerous benefits that help businesses operate safely, efficiently, and cost-effectively.
Enhanced Workplace Safety
Regular maintenance reduces the risk of sudden equipment failures that could lead to accidents or injuries. Well-maintained assets create a safer working environment and that helps the organizations to avoid potential legal and liability issues.
Extended Equipment Life
Ensuring machinery operates within recommended conditions helps protect critical components from premature wear. Addressing minor issues early prevents major damage, reducing the need for costly repairs or full equipment replacement.
Higher Operational Efficiency
Poor maintenance practices can significantly impact production output. By following a planned maintenance schedule, businesses can minimize unplanned downtime, maintain steady operations, and improve overall productivity.
Lower Maintenance and Repair Costs
Unexpected equipment failures often result in expensive emergency repairs and operational losses. Preventive maintenance allows repairs and part replacements to be planned in advance, helping control costs and avoid disruptions.
Improved Energy Efficiency
Equipment that is properly maintained consumes less energy compared to malfunctioning assets. This not only supports environmental sustainability but also helps reduce operational expenses through lower energy usage.
Let's do a comparison of the pros and cons of preventive maintenance:
When is Preventive Maintenance Required?
Preventive maintenance requirements may change in different industrial settings and scenarios depending on the equipment type, the complexity, and usage. Generally, industries follow specific standards and guidelines to determine appropriate maintenance schedules and inspection methods, helping to prevent unexpected failures. An effective preventive maintenance program should guarantee a proactive approach rather than a reactive one.

Steps Involved in Developing a Preventive Maintenance Program
1. Identify Assets
Prepare the entire list of assets, including equipment, machinery and systems that require maintenance, based on their criticality and urgency. This list must also incorporate location, usage and manufacturer information.
2. Apprehend Maintenance Needs
Understand each of the assets' individual needs for it to work efficiently. This includes inspections, servicing, spare parts analysis and evaluating manufacturers' guidelines.
3. Assess Criticality
Determine which assets are most critical to operations and safety. Equipment with high failure impact should be given top priority and must be handled carefully in maintenance planning.
4. Schedule Maintenance Intervals
Set maintenance frequency based on time, usage, or operating conditions. Proper scheduling helps prevent breakdowns without over-maintaining assets.
5. Create Detailed Procedures
Develop clear step-by-step maintenance instructions for each task. This ensures consistency, safety, and quality in maintenance work.
6. Provide Training
Train maintenance staff on equipment handling, procedures, and safety practices. Skilled teams perform tasks more efficiently and accurately..
7. Monitor and Review
Track maintenance activities and equipment performance regularly. Use this data to improve schedules, procedures, and overall effectiveness of the program.
