Only the quantitative approach using less analysis

Risk should be determined by combining the POF and the COF and the general form of the risk equation should be:

Risk = Probability x Consequence

Risk = Probability ÷ Consequence

Risk = Probability + Consequence

Risk = Probability – Consequence

The level of risk reduction achieved by inspection will depend on all of these EXCEPT:

Figure 2 is a Qualitative Risk Matrix and the arrow designates a residual risk line

Figure 2 is a Qualitative Risk Plot and the arrow designates an ISO-risk line

Which of these statements are true regarding the QRA and an RBI analysis?

The QRA typically involves a much more detailed evaluation than an RBI analysis

Both are generally performed by experienced risk analysts

There are never opportunities to link the less detailed QRA with the more detailed RBI study

None of these statements are true

The POF analysis should address all of the following items except:

Failure due to loss of containment occurring from any number of reasons due to failure modes

All damage mechanisms to which the equipment being studied is susceptible

All damage mechanisms to which the equipment being studied can be susceptible

Situations where equipment is or can be susceptible to multiple DMs (thinning, creep, etc.)

Replacement or repair of equipment

QRA uses logic models that show:

Combinations of events that could result in severe accidents

Progression of accidents and the release of hazardous material to the environment

The first step in a logical progression for a risk analysis is:

Collect and validate the necessary data and information

Determine damage susceptibility and rates

Identify DMs & determine damage mode(s) for each mechanism

Determine the POF over a defined time frame for each damage mechanism

If the scope of the RBI assessment is a multi-unit facility, the first step in the application of RBI is screening of entire process units to:

Regarding RBI planning process using the continuum of approaches, which of these statements is FALSE?

Data and Info Collection is performed only after initial Risk Assessment Process (COF/ POF)

Risk Assessment Process includes both Consequence of Failure & Probability of Failure

Risk Assessment Process results in a risk ranking that is then applied to Inspection Planning

After Inspection Plans, any Mitigation results in Reassessment & more Data & Info collection

Regarding risk management, inspection alone does not arrest or mitigate damage mechanisms or reduce risk, but the information gained though effective inspection can:

Better quantify the actual risk

Precisely identify the actual risk

Better quantify the absolute risk

Precisely identify the absolute risk

Who is responsible for assembling all of the data and carrying out the RBI analysis?

Equipment Inspector or Insp Specialist

The Materials and Corrosion specialist

QRA uses physical models that show:

Progression of accidents and the release of hazardous material to the environment

Combinations of events that could result in severe accidents

Regarding risk management, inspection is invaluable input in the prediction of when the damage will:

Result in a catastrophic failure mode

Result in a loss of containment

None of these can be determined by inspection

Non-inspection risk mitigation activities fall into all of these categories EXCEPT:

Enhance the survivability of the facility and people to the consequence

Mitigate the primary source of consequence

Reduce the magnitude of consequence

RBI requires the commitment and cooperation of:

All of the RBI team including Management

Engineering & Inspection organizations

Entire Engineering organization

COF analysis should be performed to estimate the consequences that occur due to:

A failure mode typically resulting from an identified damage mechanism(s)

Either a failure mode or deterioration typically resulting from an identified DM(s)

Deterioration typically resulting from an identified damage mechanism(s)

QRA logic models generally consist of:

None of these are correct (event trees only)

Organizations should be cautious not to assume that there is an unending capacity for risk management through inspection, and should act (how) in assigning the level of risk management achieved through inspection?

Deliberately and systematically

Conservatively and systematically

Regarding risk management with inspection, if inspection data that are gathered are not properly analyzed and acted upon where needed, what will likely be the result?

Risk mitigation will not be achieved

Significant increase in the absolute risk

Possible loss of containment & risk mitigation will not be achieved

During initial screening, the screening done at the facility level may be done by a:

Simplified Qualitative RBI assessment

Simplified Semi-Qualitative RBI assessment

Detailed Semi-Quantitative RBI assessment

Detailed Quantitative RBI assessment

Regarding RBI & Managing Operational Risk, suitability and current condition of the equipment within the established IOW (integrity operating windows) will determine:

The POF of the equipment from one or more damage mechanisms

Both the POF & COF of the equipment from one or more damage mechanisms

The COF of the equipment from one or more damage mechanisms

Regarding risk management with Inspection, whether inspections will be effective or not will depend on all of the following EXCEPT:

Amount of achievable reduction in the COF

Equipment type and the active and credible damage mechanisms affecting the equipment

The rate of deterioration or susceptibility, inspection methods, coverage and frequency

Accessibility to expected damage areas, and the shutdown requirements

An analysis that quantifies the probabilities and consequences of the probable damage mechanisms is called:

Semi-Quantitative risk analysis

What statement is true regarding risk when using a precise numeric value (quantitative risk plot) when compared to a qualitative risk matrix (precision versus accuracy)?

A precise number value implies a greater level of accuracy when compared to a risk matrix

A precise number values implies a lower level of accuracy when compared to a risk matrix

A precise number value implies a greater level of precision when compared to a risk matrix

A precise number values implies a lower level of precision when compared to a risk matrix

Which statement is false regarding the usual responsibilities of Equipment Inspector or Inspection Specialist?

He alone provides predictions of current equipment condition if condition data is unavailable

He alone implements the recommended inspection plan derived from the RBI assessment

He assesses effectiveness of past inspections with aid from Materials & Corrosion Specialist

He alone is responsible to gather data on the condition and history of equipment in the Study

Which of these statements are false regarding the relationship between RBI and PSM?

The RBI program cannot improve the mechanical integrity aspect of the PSM program

An effective PSM system can significantly reduce risk levels in a process plant

Several of the features of an effective PSM program provide input for an RBI study

RBI system will improve inspection plan focus, resulting in a strengthened PSM program

Which statement is FALSE for the upper curve in Figure 1 of API 580?

With an initial investment in inspection activities, risk generally is significantly reduced

A point is reached where additional inspection activity begins to show a diminishing return

It represents typical inspection program & where there is no inspection, risk levels are higher

If excessive insp is applied, risk levels may fall (invasive inspection may cause deterioration)

Answer explanation

Inspection Optimization Section 5.5 D … risk levels may rise = correct!

Which of these is an example of an unannounced failure?

Definitions Par 4.1.18 Two types of failures (announced/unannounced)

The probability of a fire = (Probability of Failure) X (Probability of ignition). The Analysis showed 0.0001 (POF) per year X 0.01 (ignition) = 0.000001 or 1 X 10-6 per year as the probability of a fire. If this is value is correct, then what is the probability of no fire?

Sect 12 Fig. 5 Example & Note! … Probability of all consequence Must equal 1.0 !!! Solution = 0.000001 (Probability of fire) + value “x” = (Probability of no fire) 1.0 minus 0.000001 equals 0.999999 6 numbers to left of “decimal” … So “C” is correct
