Abstract: To provide a system and a method for estimating an operational risk associated with one or more failures in at least one unit of a process plant.SOLUTION: There is a continuous stream of operational data of several variables such as temperature, pressure, etc. Detection is defined in terms of acceptable/unacceptable ranges of parameters over a finite period of time and operating load of a unit. In many cases, these predetermined parameters must be within a specified range based on operating conditions of the process plant, and a failure is detected when the measured parameters exceed the range. A risk priority number is estimated from a number of occurrences of failure mode, an average rate of change from dynamic limits with severity and a degree of correlation with detectability from operational data and dynamic limits. Herein, operating risk associated with failure modes can be calculated and updated from time to time automatically from the stream of operational data.SELECTED DRAWING: Figure 8
