Risk-based integrity and maintenance
Insights
Criticality helps direct inspection and maintenance towards the consequences that matter most to an operation. The assessment combines asset function, condition and context.
Connecting condition and consequences
Two similar items of equipment may require different priorities if they perform different functions or if one has a standby unit. Criticality incorporates the consequences of failure for safety, the environment and process continuity.
This classification must be based on shared criteria. Observed condition and degradation mechanisms provide additional information for deciding what to inspect, maintain or investigate in greater detail.
Choose a strategy consistent with the function
Tasks are selected according to the failure mode and the ability to detect or prevent its progression. An activity repeated out of habit may not address the mechanism affecting the equipment.
The review combines operating history, inspection findings and maintenance information. It also considers accessibility, resources and intervention windows so that the strategy can be translated into executable work.
Information that strengthens the assessment
Operating and maintenance history
Records should describe the condition found, the work completed and the results. Relating these records to the operating regime helps identify recurring issues and distinguish symptoms from causes.
Inspection and degradation mechanisms
The selection of inspection techniques and locations depends on the mechanisms to be assessed. Findings require technical interpretation and traceability to the equipment and its service conditions.
Asset changes
A change in load, feed or configuration may alter the assessment. Management of change must review its effect on criticality, inspection plans and maintenance.
Closing the learning loop
Monitoring compares the equipment's response with the objective of the intervention. Results may confirm the strategy or indicate a need for new data, a different task or a root cause investigation.
Maintaining this feedback prevents plans from becoming static documents. Priorities evolve with the asset and the needs of the operation.
