For every hour an engineer spends repairing or maintaining a machine, an equal number (or so it sometimes feels) are spent scratching the head wondering what might be wrong, or what is the root cause of a particular fault. If only the machines could talk to us. If only they could tell us what is wrong and, more than that, could let us know when something is likely to go wrong in the near future.
Well, this is exactly what condition-based maintenance (CBM) aims to achieve. By harnessing real-time data and smart monitoring, CBM allows our machines to tell their own story, with no more guesswork, no ‘obvious signs’ missed, and no unnecessary downtime looking for a fault that isn’t there. In this article, we’ll look at some of the questions at the heart of condition-based maintenance, and find out how it is transforming the maintenance strategies of many UK businesses.
What Is Condition Based Maintenance (CBM)?
Condition based maintenance is a proactive maintenance strategy, sometimes referred to as CBM maintenance, that uses real-time data to monitor the actual condition of an asset, such as machinery or infrastructure. Rather than sticking to a rigid, predetermined maintenance schedule, CBM uses sensors and monitoring technologies to evaluate parameters like vibration, temperature, pressure, and oil quality.
These measurements provide up-to-the-minute insights into equipment health, allowing engineers to act promptly when data suggests that intervention is necessary. For example, a manufacturing plant might use vibration sensors on rotating equipment: if a sensor detects abnormal vibration patterns, scheduled maintenance is triggered before a potential breakdown occurs. By connecting CBM platforms to cloud-based systems, businesses can access their equipment data remotely, analyse trends over time, and coordinate maintenance activities across multiple locations.
What Are The Advantages Of Condition-Based Maintenance Compared To Traditional Time-Based Maintenance?
Unlike most conventional approaches to maintenance, condition-based maintenance is a targeted approach: resources are focused on assets that show current signs of wear or fatigue, instead of servicing all equipment at set intervals whether it’s needed or not. This delivers substantial cost savings by reducing unnecessary part replacements and working hours. With CBM maintenance, the risk of large-scale breakdowns is lowered, since emerging issues are detected earlier and can be addressed proactively.
Condition-based maintenance can also minimise downtime by scheduling interventions when they are truly required, keeping machines in service for longer and increasing production availability. Real-world applications include airports, where CBM is used to monitor runway lighting and baggage handling systems, and in energy plants, where critical turbines are maintained based on their real-time condition to prevent catastrophic failures and power outages.
How Does CBM Maintenance Extend The Life Of Assets?
Condition-based maintenance extends asset longevity by preventing incidences of both under-servicing and over-servicing. Scheduled overhauls that are too frequent can lead to unnecessary disassembly and reassembly (over-servicing), which itself can introduce new faults or wear. CBM creates a ‘Goldilocks Zone’ in which maintenance is performed precisely when needed; no sooner, no later. Continuously monitoring important health indicators, such as motor temperature or lubricant quality, means that minor issues are caught early on, before becoming severe. This helps you reduce the frequency and risk of disruptive machine failures, thereby avoiding major repair expenses and extending the useful life of costly assets. For instance, an air conditioning and ventilation system in a hospital that is maintained through CBM could avoid both sudden breakdowns and excessive servicing, maintaining a reliable operation and consistent air quality. Extended asset life also translates into environmental benefits and energy savings, as machinery kept in optimal condition usually operates more efficiently and consumes less power than assets that are only fixed when something is obviously wrong.
How Is Condition-Based Maintenance Being Adopted In UK Industries?
Condition-based maintenance is rapidly gaining traction in the UK as companies recognise its potential for delivering higher reliability and returns on investment. In the manufacturing sector, for instance, CBM is now widely used to optimise preventive maintenance strategies for factory robots and conveyor systems, leading to fewer unplanned stoppages and streamlined operations. The transportation industry, meanwhile, including the rail and aviation sectors, applies CBM technologies to track the condition of rolling stock, engines, and critical infrastructure, improving safety and reducing delays. And in the oil & gas industry, the continuous monitoring of drilling equipment and pipelines by CBM systems protects against leaks and reduces pollution incidents. By integrating advanced analytics and IoT devices into their maintenance strategies, organisations in a wide range of sectors stand to benefit from more efficient workflows, reduced lifetime costs, and enhanced asset reliability.
