What is Risk Based Inspection, PoF, and CoF?

Risk Based Inspection

API 580 - API 581

RBI is an often-used word in inspection. 


RBI stands for Risk Based Inspection. 


RBI tries to answer the following questions -

1. Which part should I expect first? 

2. Which part is the most critical?

3. How should I start inspecting it first?

4. Where is the highest risk of failure? 

5. Where is the order of risk?


PoF is Probability of Failure.

This is answered by the following questions -

1. How likely is the failure to occur?

2. How frequently will the failure occur?

3. Is there an approximate time to failure or the number of failures per time?


CoF is Consequence of failure

Consequence defines how dangerous the failure will be to the resources around it.

This implies the following questions -

1. What kind of failure will it be?

2. Will it damage the components?

3. Will it be harmful to human life?

4. Will it affect/contaminate the environment?


The risk is calculated as follows -


Risk =  PoF x CoF


The number designated to Pof and Cof depends on the process and the inspecting party.


This gives an approximate ranking of which area is at the highest risk and should be inspected first.


The standards used for these are API 580 and API 581.

Corrosion risk planning - 1 - Lead acid battery

Corrosion is a quality, environment, and safety issue. Hence, it has to come under the cope of integrated management system audits However at the moment, it is more or less considered a quality issue. As such, the general tendency is to solve corrosion issues as they come. Especially in new inventions, the foresight to look for potential corrosion risk gets lost in the attempt to focus and highlight the amazing qualities of the said inventions. Hence, I have initiated this series, where I will take a component and point out the potential corrosion and damage risk areas.  Here goes the first one - lead acid battery cell. (Source:https://opentextbc.ca/chemistry/chapter/17-5-batteries-and-fuel-cells/)  Protective casing -  effect of temperature + electrolyte + contamination in electrolyte on the polymer crevice corrosion at fixtures mechanical damage during handling leading to voids for moisture ingress and oxygen/electrolyte leakage Positive terminal - corrosion of the mate...

CAREER OPTIONS IN CORROSION

  CAREER OPTIONS IN CORROSION The first time I studied corrosion was in 2009. The last 14 years have taught me one important thing - The path of a career in corrosion is not as straightforward as we are led to believe. Whether we are starting as a student of corrosion, or are entering the field after working as a non-corrosion person, there is always some career pathway that we are not aware of. There are research projects, certifications , audits, inspections , etc. EveryEng gave me the opportunity to share my learnings about the possible options in the field of corrosion . If you are someone who is starting or wants to switch to/between corrosion and its related fields, here is a short presentation for you! https://www.everyeng.com/mentor/course/view/3559864f 😀 Happy learning! 😀

FREE WEBINAR on CORROSION!
