For every hour an engineer spends repairing or maintaining a machine, an equal number are spent wondering what might be wrong. Finding the root cause of a particular fault can take just as long as fixing it.
If only machines could talk to us. If only they could tell us what is wrong. Better still, if they could let us know when something is likely to go wrong in the near future.
This is exactly what condition-based maintenance (CBM) aims to achieve. By harnessing real-time data and smart monitoring, CBM allows machines to tell their own story. No more guesswork. No “obvious signs” missed.
No unnecessary downtime looking for a fault that is not there.
In this article, we look at some of the key questions at the heart of condition-based maintenance. We also explore 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. It is sometimes referred to as CBM maintenance.
It 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 techniques to evaluate key parameters. These include:
- Vibration analysis on rotating equipment
- Temperature and motor current readings
- Pressure analysis across hydraulic systems and compressed gas systems
- Oil analysis to detect bearing wear and contaminants
These measurements provide up-to-the-minute insights into equipment health. They allow maintenance teams 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, maintenance is triggered before a potential breakdown occurs.
By connecting CBM platforms to cloud-based systems, businesses can access their asset data remotely.
They can analyse trends over time and coordinate maintenance activities across multiple locations.
This makes it easier for maintenance personnel to identify potentially failing assets before a failure occurs.
What Are the Advantages of Condition-Based Maintenance Compared to Traditional Methods?
Unlike most conventional approaches, condition-based maintenance is a targeted approach.
Resources are focused on assets that show current signs of wear or fatigue. There is no need to service all equipment at fixed intervals whether it needs it or not.
This differs from both reactive maintenance, where equipment is only repaired after it fails, and time-based maintenance, which follows a fixed schedule regardless of equipment condition.
CBM sits between these traditional maintenance methods, offering a data-driven alternative.
This delivers substantial cost savings. CBM eliminates unnecessary maintenance tasks such as part replacements and routine inspections that are not needed.
Working hours are reduced and maintenance resources are better allocated. For many organisations, this translates directly into lower maintenance costs.
With CBM maintenance, the risk of large-scale breakdowns is lowered. Emerging issues are detected earlier and can be addressed proactively.
This means maintenance teams can schedule maintenance at the right time, not too early and not too late.
Condition-based maintenance can also minimise downtime by scheduling interventions only when they are truly required.
This keeps machines in service for longer and increases production availability.
Real-world applications include airports, where CBM is used to monitor runway lighting and baggage handling systems.
In energy plants, critical turbines are maintained based on their real-time condition. This helps prevent catastrophic failures and power outages.
How Does CBM Maintenance Extend the Life of Assets?
Condition-based maintenance extends asset lifespan by preventing incidences of both under-servicing and over-servicing.
Scheduled overhauls that are too frequent can lead to unnecessary disassembly and reassembly.
This is known as over-servicing. It can introduce new faults or wear that would not otherwise have occurred.
The “Goldilocks Zone” of Maintenance
CBM creates a “Goldilocks Zone” in which maintenance is performed precisely when needed. No sooner. No later.
This means you only perform maintenance when the data tells you it is necessary. It is a smarter, more efficient approach to managing maintenance tasks.
Continuously monitoring important health indicators, such as motor temperature or lubricant quality, means that minor issues are caught early. Problems are addressed before they become severe.
This helps reduce the frequency and risk of disruptive machine failures. It avoids major repair expenses and extends the useful life of costly assets.
An air conditioning and ventilation system in a hospital maintained through CBM could avoid both sudden breakdowns and excessive servicing. This would maintain reliable operation and consistent air quality.
Extended asset life also translates into environmental benefits and energy savings. Machinery kept in optimal condition operates more efficiently.
It 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. Companies recognise its potential for delivering higher reliability and improved returns on investment.
Manufacturing
In the manufacturing sector, CBM is now widely used to optimise preventive maintenance strategies for factory robots and conveyor systems. This leads to fewer unplanned stoppages and streamlined operations.
Transportation
The transportation industry, including the rail and aviation sectors, applies CBM technologies to track the condition of rolling stock, engines, and critical infrastructure. This improves safety and reduces delays.
Oil and Gas
In the oil and gas industry, the continuous monitoring of drilling equipment and pipelines protects against leaks. It also reduces pollution incidents and supports operational efficiency.
By integrating advanced analytics and IoT devices into their maintenance strategies, organisations across a wide range of sectors stand to benefit.
The results include more efficient workflows, reduced lifetime costs, and enhanced asset reliability.
