API 580 - Practice exam Questions And Correct Answers, 100% Correct | 66 Q&A 2023/2024 Which of the following statements is correct with regard to equipment items with risks deemed acceptable by RBI analysis?A Inspection interval should be tightened B Inspection effectiveness should be adjusted C Equipment should be removed from inspection programs D No further mitigation is necessary D Which of the following statements is correct with regard to the results of quantitative analysis?A They normally provide an initial screening with which to rank units for attention.B They are usually numeric and should be comparable C They must be included in the documentation of any RBI evaluation D They are more accurate that the results of a qualitative analysis.B In RBI, residual factors for loss of containment include all of the following except: A Human Error B Unknown mechanisms of deterioration C Inspection efforts D Secondary effects from nearby units.C Compared to quantitative analysis, qualitative analysis using broad ranges

generally requires:

A a lower level of judgement, skill, and understanding.B Greater accuracy in data input to compensate for lower precision of the models C Higher level of judgment, skill, and understanding D Better training in understanding the impact of data quality C In RBI investigation, consequence analysis is intended to provide a measure of

the:

A Mitigations necessary to reduce risk.B Overall risk of a potential failure C Maximum liability for a failure D Significance of a potential failure.

D 1 / 2

Risk reduction is:

A Synonymous with risk management B Synonymous with inspection optimization C Part of risk management D Achieved only by inspection C

The value of a qualitative approach is that:

A the risk assessment process is much faster B It uses logic models that depict combinations of events C It enables completion of a risk assessment in the absence of detailed data.D It produces relative risk numbers rather than absolute risk numbers.C

RBI contributes to reduction of overall life-cycle costs by:

A using less expensive inspection techniques B Increasing the number of internal inspections C Increasing the number of non-intrusive inspections.D Enhancing the prediction of failure caused by deterioration mechanisms D Which of the following is the most important to the success of risk management by emergency isolation?

• Operations surveillance
• Chain-wheel-operated gate valves
• Fire deluge systems
• Proper isolation valve locations

D

For RBI methods, sensitivity analysis is:

• Employed only when the risk matrix indicates that the risk is high
• Normally employed to determine the effects of dominate failure mechanisms

for each piece of equipment studied.

• A review of input variables in a risk calculation to determine their influence on

the risk variables.

• Based on statistical analysis that uses historical data gathered from a

particular facility to develop a better understanding of the risk value.c The suitability and current condition of equipment within the current operating

envelope will determine the:

• Consequence of failure
• Probability of failure
• Total risk
• Likelihood
