Predictive maintenance

Definition

‍Predictive maintenance, also known as predictive maintenance, is a proactive maintenance approach that continuously monitors the health of plants and equipment to identify potential issues before they result in actual outages. This approach uses data analysis tools and technologies such as machine learning and artificial intelligence to make forecasts about maintenance requirements.

Background

‍The approach has its roots in progressive digitization of industrial processes and the increasing availability of sensor data. Historically, maintenance was either based on fixed schedules (preventive maintenance) or was carried out in response to failures (reactive maintenance). Predictive maintenance represents a development in that it determines the optimal time for maintenance work and thus minimizes downtime and extends the life of systems.

Areas of application

‍Predictive maintenance is used in numerous industries, from manufacturing to the energy sector to transportation and logistics. Wherever equipment and machinery play a critical role, this approach can increase efficiency and reliability.

Benefits

‍Key benefits include reducing unplanned downtime, extending the life of equipment, reducing maintenance and repair costs, and improving operational safety and quality.

Challenges

‍Implementing predictive maintenance can be challenging due to high initial investments in technology and training, the need to integrate with existing systems, and the need for qualified data analysts. Solutions include phased deployments, partnerships with technology providers, and training internal teams.

Examples

‍A wind turbine manufacturer could use sensors to monitor the condition of critical components in real time. Analyzing this data makes it possible to plan maintenance work exactly when it is most necessary, preventing expensive downtime and repairs.

Synopsis

‍Predictive maintenance transforms industrial maintenance by predicting failures and enabling preventive measures, reducing costs and improving operational reliability. Although implementation requires initial investment and organizational adjustments, it offers significant long-term benefits.
