Case Study

Streamlined Equipment Criticality Assessment

A refinery & petrochemical plant extension project in Saudi Arabia required to establish the equipment criticality ranking in order to prioritise maintenance and spare resources before commissioning.


ProAIM was able to complete the assessment within the short schedule period with minimum site personnel involvement. The results were satisfied and fully accepted by the client. Key critical equipment was identified aligned with site expectations. The results will form a solid basis of client’s maintenance strategies establishment.


The project only took 16 weeks to complete.  A total of nearly 60,000 tagged equipment, including mechanical, electrical and instrument, were assessed and specified criticality level.


Traditional Equipment Criticality Assessment (ECA) is qualitative basis and heavily relied on individual subject matter expert’s knowledge and experience to achieve results. It was mainly performed in workshop facilitation process which required a lot of time and personnel resources from the client. ProAIM’s streamlined ECA fully utilises the quantitative element in client’s historical data. It provides quick and accurate screening ECA results especially involving large amount of equipment.
