Several maintenance strategies are available to plant managers, namely:
• Corrective maintenance
• Preventive maintenance
• Predictive maintenance
• Detective maintenance
Corrective maintenance is the simplest method by which repair is carried out after a failure has occurred. Obviously, if the failed item of equipment is a critical part of the plant, or if it requires substantial repair efforts, corrective maintenance will not be a suitable choice.
Preventive maintenance requires regular maintenance in order to keep troublesome failure modes at bay. In a preventive maintenance strategy, we assume that regular maintenance will prevent major equipment failures and plant shutdowns.
