Engineering judgment - answer✔The basis for a qualitative probability of failure analysis is:
damage mechanisms and inspection effectiveness - answer✔Regardless of whether a more
qualitative or a quantitative analysis is used, the POF is determined by two main considerations:
materials of construction - answer✔Combinations of process conditions and
_____________________ for each equipment item should be evaluated to identify active and
credible damage mechanisms:
Risk criteria - answer✔Exchange or sharing of information about risk between the decision
maker and other stakeholders. The information may relate to the existence, nature, form,
probability, severity, acceptability, mitigation, or other aspects of risk.
failure mode - answer✔It is important to link the damage mechanism to the most likely
resulting__________
COF - answer✔In general, an RBI program will be managed by plant inspectors or inspection
engineers, who will normally manage risk by managing the POF with inspection and
maintenance planning. They will not normally have much ability to modify the
____________________:
external environment - answer✔The consequence of loss of containment is generally evaluated
as loss of fluid to the____________________:
logic model - answer✔. A quantitative method involves using a _____________depicting
combinations of events to represent the effects of failure on people, property, the business and
the environment :
accuracy - answer✔Results of a quantitative analysis are usually __________________:
precision - answer✔It is important to stress that the ____________ of the data should match the
complexity of the RBI method used :
accuracy - answer✔. The data quality has a direct relation to the relative _________________ of
the RBI analysis:
precision - answer✔It is important to stress that the ____________ of the data should match the
complexity of the RBI method used :
Damage mechanisms - answer✔__________in the hydrocarbon process industry are addressed
in API 571:
fail - answer✔Failure modes identify how the damaged component will_______________
corrosion specialist - answer✔The RBI team should consult with a ______________ to define
the equipment damage mechanisms:
process - answer✔Identifying trace constituents (ppm) in addition to the primary constituents in
a ____________can be very important as trace constituents can have a significant affect on the
damage mechanisms:
failure mode - answer✔Once a credible damage mechanism(s) has been identified, the associated
_______________ should also be identified:
damage - answer✔In some cases, damage by one mechanism may progress to a point at which a
different mechanism takes over and begins to dominate the rate of __________________:
loss of containment - answer✔The probability analysis in an RBI program is performed to
estimate the probability of a specific adverse consequence resulting from a ______________that
occurs due to a damage mechanism(s):
truck off-loading - answer✔. It should be noted that damage mechanisms are not the only causes
of loss of containment. Other causes of loss of containment could include but are not limited to
all EXCEPT the following:
What is RBI benefits. - answer✔(a) an overall reduction in risk for facilities and equipment
assessed.
(b) An acceptance/understanding of the current risk.
process - answer✔Changes in the __________________, such as pressure, temperature or fluid
composition, resulting from unit abnormal or upset conditions should be considered in the RBI
assessment:
completeness - answer✔The _______________ of the data should be consistent with the RBI
