## Risk Based Inspection – Metric

Risk based inspection Metric     Risk Based Inspection is a study to develop inspection plan based on equipment risk ranking. Mathematically, Risk is defined as PoF x CoF. What is PoF ? PoF or Probability of failure is a rank that tell us about how likely a equipment will fail. CoF or Consequence of failure is a rank that tell us about how much failure impacts. In a simple way PoF, CoF and Risk are 3 terms that we used to rank all equipment in a company. Risk based inspection metric may consist of 3×3 , 4×4, 5×5 or even 6×6. For a company has a small quantity of equipment, they may choose to use 3×3 metric. But for company that have a lot of equipment -e.g. 1,000,000- with wide range of consequence, they may prefer to use 6×6 metric. This metric tell us about how detail we group[…]

## Mechanical Engineer creates value from Risk Based Inspection

how to get a vlue from risk based inspection ? A wise man said “if you buy a product from a manufacturer at \$100 and sell it again to customer at \$120, it is traditional trader. You need more than that. Successful man is selling a product at \$120 even there is not manufacturer available yet.” In previous articles, we learned about processing data to provide lower inspection cost. In simple way, we can classify that activities into 3 block diagram: input, process and output. IPO diagram : Input – Process – Output Input  : last inspection record, equipment data, Risk Based Inspection-RBI study, inspection cost Process  : inspection planning using simple tool i.e. excel spreadsheet Output : inspection schedule, inspection budget and the most important is “lower inspection cost by 50%” Customer : his supervisor, Inspection Manager It just an example of Mechanical engineer job in oil and gas[…]
