P-RBI
Petronas-Risk Based Inspection (P-RBI) A method that have been approved to
meet the requirements of API 580 and being used by PETRONAS
ObjectivesTo focus inspection resources on critical
equipment which will prevent failures.
P-RBI Benefits Reduce costs Provide well defined steps to improve plant
performance Optimize inspection ,test and maintenance work. Reduce and ultimately eliminate unplanned
equipment failures.
P-RBI Reduces Risk……How??Finding and fixing problem before lead to leaks.An item will be removed from its service if it risk
reach unacceptable level.

Data ExampleP-RBI On Storage Tank T-1201
Data Collection We get data for the equipment from:
General Arrangement (GA) Ultrasound Thickness Test (UT) PFD and P&ID Manufacturer Equipment Data Sheet (U-1 Report)
Data Collection Pitfalls Incomplete data collection Inappropriate sourceCut and paste errors Incorrect “units of measure”
P-RBI On Storage Tank T-1201
Equipment History & Visual Inspection = Inspection History
• Help to establish the level of deterioration• Rate of deterioration• Confidence Level
Probability of leak is based on how well we know the true condition of the item

Corrosion Study Corrosion study help to understand how the
equipment will fail Its also used to establish appropriate Inspection
