API-580 Exam Dumps : API 580 - Risk Based Inspection

Per Section 13.3 of API 580:

“A Fitness-For-Service (FFS) assessment (e.g., API 579-1/ASME FFS-1) may be performed to determine what size flaws, if found in future inspections, would require repair or equipment replacement.”

This makes Fitness-For-Service the correct method for evaluating whether existing or predicted flaws are tolerable or require corrective action.

As stated in Section 11.4 of API 580:

“Sensitivity analysis typically involves reviewing some or all input variables to the risk calculation to determine the overall influence on the resultant risk value.”

This process helps identify which input variables most significantly affect the final risk values. Such variables are prioritized for validation and refinement to improve the quality of the analysis.

As stated in API 580 Section 7.3:

“The data quality has a direct relation to the relative accuracy of the RBI analysis. Although the data requirements are quite different for the various types of RBI analysis, quality of input data is equally important no matter what approach to RBI is selected.”

This highlights that data quality is critical across qualitative, semi-quantitative, and quantitative analyses.
