Corrective Planned Maintenance

A few posts ago we talked a little about electrical preventive maintenance and why it is so important. In this post we will talk about another type of maintenance, corrective planned maintenance. Read on to learn more about it!

Planned corrective maintenance is defined as maintenance work that involves repairing or replacing components that have failed or broken. It’s like its name suggests: fix something that’s abnormal.

To prevent a failure from occurring, corrective maintenance must be the result of regular inspection, which identifies the failure in time for corrective maintenance to be planned and scheduled, then performed during a routine shutdown of the industrial plant.

When corrective maintenance is performed, the equipment should be inspected to identify the reason for the failure and to allow action to be taken to eliminate or reduce the frequency of similar future failures. These inspections must be included in the work plan.

Corrective maintenance can be defined as maintenance that is required when an item has failed or is worn out, with the aim of bringing back the work order.

Planned corrective maintenance is performed on all items for which the consequences of failure or wear are not significant and the cost of this maintenance is no greater than preventive maintenance.

Corrective maintenance activity may consist of equipment restoration, repair or replacement.

Types of corrective maintenance

Tipos de manutenção corretiva

Planned corrective maintenance is a set of activities that are performed to eliminate the source of failure, without interrupting the continuity of the production process.

The way to carry out this type of corrective maintenance is by removing the item to be corrected from the production line and replacing it with another item.

Deferred maintenance is a set of corrective maintenance activities that are not immediately initiated after a failure occurs, are delayed, but which will not affect the production process.

Shutdown corrective maintenance is a set of corrective maintenance activities that are performed when the production line is in a total shutdown situation.

The main objectives of corrective maintenance are to maximize the effectiveness of all critical plant systems. In addition to eliminating breakdowns, eliminating unnecessary repairs and reducing deviations from optimal conditions.

The difference between corrective maintenance and preventive maintenance is that, for corrective maintenance, the failure must occur before any corrective action is taken.

The way to perform corrective maintenance activities is by performing four important steps:

fault detection

Fault isolation

Eliminating Failures

Verification of the elimination of faults

In the defect elimination step, several actions could be taken such as adjustment, alignment, calibration, rework, removal, replacement or renewal. Planned corrective maintenance has several prerequisites to be performed effectively:

repair procedures

Adequate time to repair

Repair check
