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

Section 5.3.6 of API 580 states:

“Use of expert opinion will typically be included in most risk assessments regardless of type or level.”

This confirms that expert judgment is a fundamental component across all levels of RBI, whether qualitative, semi-quantitative, or quantitative.

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.

According to Section 7.2.3:

“Quantitative RBI uses logic models depicting combinations of events that could result in severe accidents and physical models depicting the progression of accidents… Hence more detailed information and data are needed for a fully quantitative RBI in order to provide input for the models.”

The need for detailed data in quantitative analysis is primarily to enable the use of logic and physical models in assessing risk.
