In manufacturing industries, plant maintenance refers to the activities and processes undertaken to ensure the proper functioning, reliability, and longevity of equipment, facilities, and infrastructure. There are several Types of Maintenance processes that organizations may implement:
- Preventive Maintenance or Time-Based Maintenance (TBM)
- Condition-Based Maintenance (CBM)
- Predictive maintenance
- Reactive Maintenance – Breakdown Maintenance
- Planned Maintenance
- Corrective Maintenance.
- Shutdown Maintenance – Turnaround Maintenance
- Total Productive Maintenance (TPM)

TYPE OF MAINTENANCE | MAINTENANCE CATEGORY
The several Type of Maintenance processes or Maintenance Categories used in the organizations are briefly described:
Preventive Maintenance
Preventive maintenance is a proactive approach that includes scheduled inspections, servicing, and repairs to prevent equipment failure. It aims to identify and address potential issues before they cause significant disruptions or breakdowns.
Condition-Based Maintenance
Condition-based maintenance relies on the continuous monitoring of equipment conditions using sensors and data analysis. It involves performing maintenance activities based on real-time equipment health and performance data, optimizing maintenance efforts and resources.
Predictive Maintenance
Predictive maintenance relies on advanced technologies and data analysis to identify patterns or indicators of equipment failures. It involves monitoring parameters such as vibration, temperature, and pressure to detect deviations from normal operating conditions. By predicting failures, organizations can perform maintenance activities at the optimal time, reducing downtime and minimizing costs.
Reactive Maintenance (Breakdown Maintenance)
This type of maintenance is performed in response to equipment breakdowns or failures. It involves repairing or replacing damaged components or systems to restore functionality quickly.
Planned Maintenance
Planned maintenance involves scheduling maintenance activities in advance based on predetermined criteria. It ensures that maintenance tasks are performed regularly to prevent equipment deterioration and promote optimal performance.
Corrective Maintenance
Corrective maintenance involves fixing equipment or systems after they have failed or experienced a significant deviation from normal operating conditions. It focuses on identifying and addressing the root causes of failures to prevent recurring issues.
Shutdown Maintenance (Turnaround Maintenance)
Shutdown maintenance refers to the comprehensive maintenance activities undertaken during planned shutdowns or scheduled plant downtime. It includes inspections, repairs, and upgrades that cannot be carried out during regular operation.
Total Productive Maintenance (TPM)
TPM is a holistic approach that aims to maximize the overall equipment effectiveness-OEE and reliability of the systems. It involves involving all levels of the organization to actively participate in maintenance activities, including operators, maintenance personnel, and management.
These types of maintenance can be implemented individually or in combination, depending on the specific needs and requirements of the manufacturing facility. The goal is to ensure optimal uptime, minimize disruptions, extend equipment life, and reduce overall maintenance costs.
