The major topics dealt with in this paper include identification of items to be maintained under a preventative maintenance schedule (PM) in a facility and the assessment of the criticality of each of the nominated items of plant. Based on the asset listing a preventative maintenance schedule and inspection plan, covering simple inspection, trade level overhaul tasks and condition monitoring tasks may be established. Supporting the schedule are requirements for sub-contractor agreements and services, and statutory registers. Where possible recommendations on critical spares holdings and best practice maintenance policies should be supplied. The whole process is managed with a planning and scheduling approach, and measured by KPIs for reporting maintenance performance.
