Abstract
The continuous and uninterrupted operation of process plants which is most essential for their profitable performance depends on reliability and availability of all the critical process equipment. Maintenance department provides chief support for the safe, reliable and successful functioning of a process plant. Process critical equipment must be effectively monitored and maintained so that they can support the continuous production in the plant. Some of the key elements required for the successful functioning of the maintenance team are briefly outlined in this manuscript. Though it could be exhausting to conscientiously apply all such principles regularly, it shall be in the benefit of the organization to consider and apply such concepts as much as possible.
