Abstract

A computer implemented method includes receiving, by the computer, a request to display a process safety risk matrix associated with a process facility and displaying the process safety risk matrix. The process safety risk matrix includes a 2-dimensional representation of a plurality of risk matrix cells, each of the plurality of risk matrix cells associated with a combination of a likelihood level and a severity level. The computer implemented method includes displaying, by the computer, an indication of a hazardous process event scenario within a first cell within the process safety risk matrix, the cell location determined based on a Target Mitigated Event Likelihood (TMEL) and a Safety Severity. The computer implemented method includes displaying, by the computer, an indication of a second graphic indication on a second cell to identify a change in a hazardous scenario count associated with the second cell.

Description

RELATED APPLICATION This application is a U.S. national stage application filing under 35 U.S.C. 371 from International Application No. PCT/US2021/037103, filed Jun. 11, 2021, and published as WO 2021/252964 A1 on Dec. 16, 2021, which claims priority to U.S. Provisional Application Ser. No. 63/038,766 (entitled Operations Safety Advisory, filed Jun. 13, 2020) which applications are incorporated herein by reference. BACKGROUND A processing plant may include one or more processes that have associated process risks. For example, a plant may include a pressure vessel used to store hydrocarbons, where uncontrolled high pressure can lead to vessel rupture and release of hydrocarbons in the atmosphere. This process risk leads to a potentially hazardous event, such as an explosion, injury, or death. A Safety Instrumented Function (SIF) is used to reduce the likelihood of a hazardous event. However, each SIF may not provide the intended safety features, such as through SIF failure or manual bypass of the SIF, and may not provide adequate protection against hazardous events. SUMMARY A computer implemented method includes receiving, by the computer, a request to display a process safety risk matrix associated with a process facility and displaying the process safety risk matrix. The process safety risk matrix includes a 2-dimensional representation of a plurality of risk matrix cells, each of the plurality of risk matrix cells associated with a combination of a likelihood level and a severity level. The computer implemented method includes displaying, by the computer, an indication of a hazardous process event scenario within a first cell within the process safety risk matrix, the cell location determined based on a Target Mitigated Event Likelihood (TMEL) and a Safety Severity. The computer implemented method includes displaying, by the computer, an indication of a second graphic indication on a second cell to identify a change in a hazardous scenario count associated with the second cell.
