Planned maintenance in industrial facilities is a critical process to ensure the efficient operation of equipment and machinery.
What is Planned Maintenance?
Planned maintenance refers to maintenance activities performed at regular intervals before equipment and systems fail. This maintenance is generally carried out in a planned manner to extend the lifespan of machines, reduce downtime, and prevent interruptions in production processes. The most important feature of planned maintenance is that it is performed based on a predetermined schedule before the need actually arises. In this way, the risk of equipment failure is minimized, and the efficient operation of machines is sustained.
In industrial facilities, planned maintenance not only controls the physical condition of equipment but also creates a critical strategy for achieving long-term production goals. This type of maintenance is a significant step in ensuring the continuity of production lines and optimizing maintenance costs.
What Are the Types of Planned Maintenance?
Planned maintenance in industrial facilities is generally divided into three main types: periodic maintenance, preventive maintenance, and predictive (warning) maintenance. Since each of these maintenance types has a specific purpose and method of application, they carry great importance for sustaining the efficient operation of the facility.
Periodic Maintenance
Periodic maintenance consists of maintenance performed regularly within a specific timeframe. This type of maintenance is carried out when equipment reaches a certain milestone or operating time. Periodic maintenance ensures business continuity by preventing unexpected machine failures. For example, operations such as periodic oil changes or filter cleaning in motors and pumps fall under this type of maintenance.
Preventive Maintenance
Preventive maintenance is the set of planned operations performed to ensure equipment fulfills its functions before it malfunctions. This type of maintenance plays a critical role in ensuring that machines operate efficiently for a longer period. For example, checking the parts of a generator at certain intervals and replacing worn parts are examples of this type of maintenance. Preventive maintenance not only prevents equipment failures but also prevents high-cost major repairs.
Predictive Maintenance
Predictive maintenance is a type of maintenance performed using sensors or systems that continuously monitor the status of equipment. Systems tracking the equipment's condition detect potential problems that could lead to failure and warn the user for maintenance operations. In this way, the need for maintenance is detected earlier, and unnecessary interruptions are prevented. Predictive maintenance is generally preferred in machines requiring high precision, such as robots in production lines and sensitive machinery.
What Are Planned Maintenance Implementation Strategies?
To successfully manage planned maintenance practices in industrial facilities, certain strategies must be followed. These strategies increase the effectiveness of maintenance while optimizing costs. In this section, we will look at the main strategies used to apply planned maintenance efficiently.
Maintenance Management Systems
Maintenance Management Systems (BMS/CMMS) are software used to plan, monitor, and manage maintenance operations. These systems help track equipment maintenance needs, optimize maintenance plans, and record maintenance history. Thanks to maintenance management systems, the maintenance calendar can be created accurately, ensuring maintenance activities are carried out on time. Additionally, systems can be used to predict future maintenance needs by keeping records of failures experienced and operations performed during maintenance.
KPIs and Performance Monitoring
KPIs (Key Performance Indicators) are important indicators used to measure the effectiveness of maintenance processes. These indicators play a critical role in evaluating the success of the maintenance process. Thanks to KPIs, it is possible to monitor how efficiently maintenance is performed, how much downtime has decreased, and how long equipment runs without problems. Performance monitoring ensures the continuous improvement of maintenance strategies, and potential disruptions in the system are immediately detected and resolved.
Training and Personnel Development
Training and personnel development is another critical strategy for the success of planned maintenance practices. Maintenance personnel must be trained regularly, follow technological developments, and master new maintenance methods. Training helps reduce errors made in maintenance processes, protect equipment correctly, and resolve failures quickly. At the same time, the application of correct maintenance techniques by personnel reduces the maintenance costs of businesses and ensures production continuity.
Technology and Automation
Technology and automation is an important strategy to make planned maintenance practices more efficient. Automation systems speed up maintenance processes while minimizing the margin of error. Thanks to technology and automation, machine performance can be monitored instantly, and maintenance needs can be detected automatically. For example, through sensors, vibration, temperature, and other parameters of machines can be monitored, and any unusual situation can be immediately detected to start the maintenance process. This ensures the prevention of unexpected failures and helps maintenance processes become more efficient.
What Are the Advantages of Planned Maintenance?
Planned maintenance plays a critical role in ensuring long-term efficiency and safety in industrial facilities. This type of maintenance not only ensures the proper functioning of machines but also has many operational advantages. We can summarize the main advantages provided by planned maintenance as follows:
Reduction of Downtime
Planned maintenance significantly reduces the risk of equipment failing unexpectedly. Equipment is repaired with small interventions detected in the early stages thanks to checks made at certain intervals. In this way, major failures are prevented, and downtime is minimized. For example, a worn part detected during the periodic maintenance of a machine is replaced before it completely fails, preventing interruptions that could occur on the production line.
Ensuring Production Continuity
Production continuity is one of the most important goals of industrial facilities. Planned maintenance guarantees this continuity by ensuring that machines are regularly checked and maintained. Taking equipment into maintenance at certain intervals prevents disruptions in production processes. In this way, facilities continue to operate uninterrupted without unexpected stops or failures occurring on production lines. This facilitates achieving production goals and ensures timely responses to customer demands.
Cost Savings
Planned maintenance provides major cost savings in the long run. When equipment is repaired during minor faults, large-scale and expensive repairs are prevented. Additionally, by ensuring machines operate efficiently, energy consumption and other operating costs decrease. For example, thanks to regular maintenance, motors can be ensured to run efficiently, which reduces energy costs. At the same time, planned maintenance ensures that labor and spare part demands are managed more efficiently, thus minimizing unnecessary expenses.
Extending Equipment Lifespan
Planned maintenance extends the life of equipment. Thanks to regular maintenance, machines can operate efficiently for a longer time instead of wearing out over time. Small interventions made to prevent equipment from failing at an early age prevent major repairs and early decommissioning. This allows for getting a return on investment for a longer period, especially in high-cost machines. For example, regular cleaning of a pump and checking its parts ensures the pump operates efficiently for many years.
Safe Working Environment
Planned maintenance helps create a safe working environment in industrial facilities. Regular maintenance ensures the proper functioning of equipment, preventing work accidents and security threats. Issues detected during maintenance that carry risks are quickly resolved, thus ensuring the safety of employees. Additionally, the safe operation of equipment ensures the protection of important data and processes belonging to the business. For example, maintaining a security system or fire alarm device prevents such devices from failing unexpectedly and increases the safety of the facility.
What Are the Disadvantages of Planned Maintenance?
Although planned maintenance generally provides great benefits in industrial facilities, it may have some disadvantages. However, these disadvantages can be minimized with the right strategies and planning.
One of the primary disadvantages is related to time and labor costs. Planned maintenance operations require regular maintenance activities performed based on a specific schedule. This process can be time-consuming, and focusing on every machine can be challenging in terms of time for maintenance teams, especially in large facilities. Therefore, the labor and time allocated for maintenance activities can lead to high costs in some cases. However, this situation can be minimized by planning maintenance processes well and managing personnel effectively.
Another potential disadvantage may be related to over-maintenance. If maintenance activities are performed too frequently, labor and resource waste may occur as a result of unnecessary maintenance on some machines. In this case, it is important to use the right timing strategies to ensure maintenance is done only when necessary. Thus, unnecessary maintenance activities can be avoided, and a more efficient maintenance process can be ensured.
