About Unmitigated Risk

When you calculate an RBI Analysis, the Meridium Enterprise APM system locates the Criticality Consequence Evaluation record to which it is linked. In that Criticality Consequence Evaluation record, the following fields contain a value, which represents a consequence on the same Risk Matrix that was used to calculate the Inspection Priority:

• Flammable Consequence Category
• Toxic Consequence Category
• Environmental Consequence Category

Note: The Environmental Consequence Category field will contain a value only if the Criticality Calculator RBI Components record contains the value Storage Tank - Bottom in the Component Type field.

To determine the unmitigated risk for each RBI Degradation Mechanisms record, the Meridium Enterprise APM system plots the following values on the Risk Matrix to determine a temporary unmitigated risk value:

• The highest value from the fields in the previous list.
• The calculated Probability of Failure in the RBI Degradation Mechanism record.

The Meridium Enterprise APM system then locates the Risk Translation record with this temporary unmitigated risk value in the Source Risk Rank field and the value No (N) in the Financial? field.

When you calculate an RBI Analysis, the Meridium Enterprise APM system locates the Criticality Consequence Evaluation record to which it is linked. In that Criticality Consequence Evaluation record, the following fields contain a value, which represents a consequence on the same Risk Matrix that was used to calculate the Inspection Priority:

• Lost Production Category
• Product Leak Category

Note: The Product Leak Consequence field will contain a value only if the Criticality Calculator RBI Components record contains the value Heat Exchanger - Bundle in the Component Type field.

To determine the unmitigated financial risk for each RBI Degradation Mechanisms record, the Meridium Enterprise APM system plots the following values on the Risk Matrix to determine a temporary unmitigated financial risk value:

• The highest value from the fields in the previous list.
• The calculated Probability of Failure in the RBI Degradation Mechanism record.

The Meridium APM system then locates the Risk Translation record with this temporary unmitigated risk value in the Source Risk Rank field and the value Yes (Y) in the Financial? field.
