RECOMMENDED PRACTICE SUMMARY SHEET
Contents:
Scope andapplication:
Items covered by the RP include:g Concept of Risk Based Inspectiong Qualitative and quantitative RBI methodsg Calculation of consequence of failureg Calculation of probability of failureg Risk-based inspection planningg Updating of risk following inspectiong Modelling of consequence of failure for safety and economic consequencesg Modelling of degradation mechanismsg Use on piping, pressure vessels, tanks, heat exchangers, pig launchers and traps
The purpose of this recommended practice is to describe a method by which a risk basedinspection (RBI) plan may be established for offshore production systems.The document outlines methods for evaluating probability and consequence of failure, makingan assessment of the risk level, and concluding on the appropriate actions, such as inspection,that can be taken to manage that risk.
The objectives of this RP are to:g provide an internationally acceptable practice for carrying out risk-based inspection planing
for offshore topsides pressure systemsg achieve an optimal schedule for the inspection activities whilst ensuring that the overall
installation risk acceptance criteria, set by the operator, are not exceededg identify and apply the optimal inspection or monitoring methods according to the identified
degradation mechanismsg specify procedures and methodology to be followed for optimal inspection planning to focus
inspection effort on items where the economic or safety risks are identified as being high, andsimilarly to reduce the effort applied to low risk systems
