API-580 Exam Dumps - API ICP Programs Questions and Answers

API 580 highlights that while cost reduction is a potential benefit of RBI, the true focus is risk management and equipment integrity. From Section 12.5:

“Inspection costs can be more effectively managed through the use of RBI… The user should recognize that while there is a potential for the reduction of inspection costs through the utilization of RBI, increased equipment integrity and inspection cost optimization should remain the focus.”

This confirms that the main driver for RBI is not cost elimination, but rather the intelligent allocation of inspection resources to preserve equipment integrity.

Option B is incorrect because RBI does not guarantee elimination of internal inspections — only that some may be deferred or replaced with alternative methods.

Option C generalizes effectiveness without case-by-case evaluation.

Option D is false; RBI is designed to optimize, not increase costs.

API 580, Section 4.2 defines risk reduction as:

“Risk reduction is the act of mitigating a known risk that is deemed to be too high to a lower, more acceptable level of risk with some form of risk reduction activity.”

Risk assessment and risk determination involve identifying and evaluating risk.

Risk management is the broader process that may or may not involve mitigation.

According to API 580, Section 3.1.28, the definition is clearly stated:

“Logic model: A tool used to depict the effectiveness in depicting a combination of events that could result in a loss of containment event.”

While a physical model (Option A) may represent the progression of release events, and other options (B and D) are not defined within API 580, only a logic model fits the definition used in RBI methodologies to evaluate event combinations leading to failure.

According to Section 8.3 of API 580:

“Once a credible damage mechanism(s) has been identified the associated failure mode should also be identified… Examples of failure modes include the following:

a) pinhole leak

b) small to moderate leak

c) large leak

d) ductile rupture

e) brittle fracture.”

Rupture is clearly listed as a type of failure mode. In contrast:

Stress corrosion cracking (B), general corrosion (C), and embrittlement (D) are damage mechanisms, not failure modes.

API 580, Section 9.3.1 confirms:

“Most probability assessments use a blend of qualitative and quantitative approaches.”

This reflects that in practice, assessments exist on a continuum, combining qualitative insights (expert judgment) with quantitative data where available.

According to Section 7.3 of API 580:

“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 clearly establishes that regardless of whether a qualitative, semi-quantitative, or quantitative RBI method is chosen, the quality of data must remain consistently high to ensure meaningful risk assessments.

API 580 provides the following standard definition under Section 3.1.62:

“Risk: The combination of the probability of an event and its consequence.”

This is the classic risk formula used throughout the RBI methodology: Risk = PoF × CoF. The other options overcomplicate or misrepresent this core principle.
