Intorduction:
This document provides information on using risk analysis to develop an effective inspection plan. Inspection planning is a systematic process that begins with identification of facilities or equipment and culminates in an inspection plan.

Both the probability of failure and the consequence of failure (COF) should be evaluated by considering all credible damage mechanisms that could be expected to affect the facilities or equipment. In addition, failure scenarios based on each credible damage mechanism should be developed and considered. The output of the inspection planning process conducted according to these guidelines should be an inspection plan for each equipment item analyzed that includes: a) inspection methods that should be used,

b) extent of inspection (percent of total area to be examined or specific locations), this information shall be provided by specifying effectiveness of the inspection and related document shall indicate extent of inspection to be performed. c) inspection interval or next inspection date (timing),

e) the residual level of risk after inspection and other mitigation actions have been implemented. f) Marked PIDs indicating Dead legs and Corrosion Circuits in two different sets. The RBI plan produced according to the guidance herein, combined with a comprehensive set of integrity operating windows for each process unit and a rigorous MOC program should provide the basis for sound management of the integrity of fixed equipment in the refining and petrochemical process industry. RBI is synonymous with risk-prioritized inspection, risk-informed inspection and with inspection planning using risk based methods. All the assumptions made / criteria used need to be recorded into an assumption file in a share drive. This will ensure the uniformity in the approach used.

Mechanical Integrity Focused
The RBI process is focused on maintaining the mechanical integrity of pressure equipment items and minimizing the risk of loss of containment due to deterioration. RBI is not a substitute for a PHA or hazard and operability assessment (HAZOP). Typically, PHA risk assessments focus on the process unit design and operating practices and their...
