12 - Risk Management with Inspection Activities Flashcards
risk can be managed by ,,,,,,
inspection
Impending failure of pressure equipment is not avoided by inspection activities unless the
inspection precipitates risk mitigation activities that change ,,,,,
the POF
The better the predictability, the less ,,,,, there will be as to when a failure may occur
uncertainty
The reduction in uncertainty and increase in predictability through inspection translates directly to a better estimate of the probability of a failure and therefore a ,,,,
reduction in the calculated risk
Users should be diligent to assure that temporary inspection alternatives, in lieu of more permanent risk reductions, are ,,,,,
actually effective
Risk mitigation achieved through inspection presumes that the organization will act on the results of the inspection in a ,,,,,
timely manner.
Identifying Risk Management Opportunities from RBI Results:
typically a risk priority list is developed as a result of ,,,,
the RBI process
Identifying Risk Management Opportunities from RBI Results:
Higher risk items should also be assessed for ,,,,,
potential risk management actions.
Establishing an Inspection Strategy Based on Risk Assessment:
spot thickness readings on a piping circuit would be considered to have little or no benefit if the damage mechanism results in ,,,,,
unpredictable localized corrosion (e.g. pitting, ammonia bisulfide corrosion, local thin area, etc)
Establishing an Inspection Strategy Based on Risk Assessment:
The inspection strategy shall be a ,,,,, process to assure that inspection activities are continually focused on items with higher risk.
documented, iterative
Managing Inspection Costs with RBI:
managing inspection costs is by identifying items in the inspection plan that can be inspected,,,,,,,,
non-intrusively on-stream.
