Risk-Based Inspections (RBI)
Safeguarding Asset Integrity
Establish process and practices to manage risk. Use Ivara EXP software to select cost effective and appropriate maintenance and inspection tasks and techniques, while optimizing effort and cost. With Ivara’s RBI program you will shift from a reactive to a proactive maintenance regime, producing an auditable system, provide an agreed “Operating window”, promote team work and manage risk.
Move away from time based inspections governed by minimum compliance with rules, regulations and standards for inspection. Apply a strategy of doing what is needed for safeguarding integrity and improving reliability and availability of the unit by planning and executing required inspections. Provide economic benefits such as fewer inspections, shorter shutdowns, longer run length, and less frequent shutdowns.
Risk Based Inspections consist of the following components:
- Risk Identification, allowing you to define the risk associated with a failure mode. Risk is defined as the probability of failure times the consequence of failure.
- Inspection Frequency, automatically adjusts an indicator’s collection frequency based on the age and/or condition of the asset. The higher the risk, the more frequently the inspection is performed, that is the shorter the failure mode and indicator frequency. Inspection strategies are evaluated as equipment condition changes. An inspection frequency profile consists of:
- A triggering rule
- Probability of failure
- Inspection Task Builder, automatically maintains the relationship between standard tasks and indicators. Includes changes to standard task triggering to selectively include only the indicators due to be collected.
- Indicator Collection Compliance, tracks compliance of indicator collection.
