API 580 notesTRANSCRIPT
1.Caution is advised in being too conservative, asoverestimating consequences and/or POF values willunnecessarily inflate the calculated risk values.2.Risk Assessment Personnel. This person(s) should have a thorough understanding of risk analysis byeducation, training, and/or experience. He/she should have received detailed training on the RBImethodology and on the procedures being used for the RBIassessment.3.Boundary limits are identified to determine what is vitalto include in the assessment.4.Managing Risk by Reducing Uncertainty Through Inspection5.RBI process should be the linkage ofrisks with appropriate inspection, process control or other riskmitigation activities to manage the risks.6.The primary work products of the RBIassessment and management approach are plans thataddress waysto manage risks on anequipment level.7.An ISO-risk line represents a constant risk level8.Achieving Lowest Life Cycle Costs with RBI.RBI should enhance the prediction of failures caused bydamage mechanisms.9.Risk reduction is only part of risk management.10.Risk-based inspection is a tool to provide an analysis of the risks of loss of containment of equipment.11.Risk of fire numerical.12.Removal of dead-legs, provide mitigation of POF.13.Risk avoidance14.Group components that have the same material ofconstruction and are exposed to the same internal andexternal environment.15.Safety consequences could be expressed based on the severity ofan injury (e.g. fatality,serious injury,medical treatment, first aid) or expressed asa category linked to theinjury severity (e.g. A through E).16.A key element in determining the magnitude of the consequence is thevolume of fluid released.17.The equipment inspector or inspection specialist is generally responsible for gathering data onthecondition and history of equipment in the study.18.Risk Analyst is responsible for assembling all of the data and carrying out the RBI analysis19.Failure Mode small hole.20.Quality of input data is equally important no matter what approach to RBI is selected.21.The purpose of establishing operational boundaries is to identify key process parameters thatmay impactdeterioration.22.The primary product of an RBI effort should be an inspection plan for each equipment item evaluated.23.The level of the unmitigated risk should beused to evaluate the urgency forperforming the inspection.24.An RBI assessment made on new equipment or anew project, while in the design stage, mayyieldimportant information on potential risks.25.A qualitative analysis using broad ranges requires ahigher level of judgment, skill andunderstanding fromthe user than a more quantitative approach.26.Record of the team members involved should be captured,as well as the skillset that they bring to theteam for RBI purposes. This will behelpful in understanding the basis for the riskassessment when theanalysis is repeated or updated.27.Nature and extent of damage mechanism,is often unpredictable.28.The RBI process is focused onmaintaining the mechanical integrity of pressure equipment items.29.Probability of failure of specific consequence is depending on. 1) Magnitude of event 2) consequence offailure.30.The main production consequences for RBI are financial.31.The data quality has a direct relation to the relative accuracy of the RBI analysis.
