Consequence of Failure (COF)

Consequence of Failure (COF) is one part of the equation to determine risk as part of Risk Based Inspection (RBI) methodology. The COF, calculated together with the Probability of Failure (POF), helps establish the risk level for particular piece of equipment and set inspection intervals based on the calculated risk.

COF is calculated by reviewing and ranking the potential consequences for the equipment, personnel, environment, etc. in the event of equipment failure. More details on COF are given in API RP 580 - Risk Based Inspection (RBI), which contains directions on developing, implementing and maintaining an effective RBI program.

However, in the current cost reduction environment, some companies are adopting a very risky strategy for piping systems where maintenance and inspection tasks are reduced and eliminated indiscriminately, without considering the relative importance of piping for the process.
