The role of Maintenance Engineer, also called a Plant Engineer, covers everything from equipment and component maintenance strategy selection, equipment maintenance cost modelling, life cycle analysis, operational risk management—right through to re-engineering equipment for reliability improvement.
A Maintenance Engineer is the second person called-in when equipment is not operating properly. The first person called to address the problem plant and equipment is the appropriate Maintenance Technician. When the technician cannot solve the problem the maintenance engineer is called in to help resolve the issue correctly. Since the job involves solving difficult engineering problems a Maintenance Engineer needs to understand the engineering design of their equipment and the science of their processes. I
To be a great Maintenance Engineer you must be expert in how your plant and equipment work, how they are designed and constructed, and how they are correctly used. There is no better way to be successful as a Maintenance Engineer than to know why problems arise in your plant and know how to properly solve them. This is especially the case when it becomes necessary to improve the reliability of plant and equipment. To make plant highly reliable you must extend their life between outages by twice and three times; hopefully many times more. To make that much difference to your operation you must know and understand the causes of failure and then find excellent answers that greatly extend lifetimes. To do that you must understand the applicable engineering, process science, process control and materials-of-construction properties so well that you confidently make good choices.
Similarly, when you need to select maintenance strategy, choose maintenance activities and set maintenance frequencies for plant and equipment, you will make far better decisions when you know the engineering and the operating properties and parameters of your process and equipment.
Plant Engineering and Maintenance Engineering are genuine professional engineering roles. The incumbent needs to understand physics, metallurgy, process control, process chemistry and many other sciences that affect their plant and equipment. A specialist maintenance engineer like a Mechanical, Electrical and Instrumentation Maintenance Engineer needs to know their primary disciplines, and the application of them, exceptionally well.
