(100c) Dynamic Risk Advisor: A Real-Time Risk Analysis Tool for Process Safety Management

In recent years, the topic of Process Safety has been gaining strength in the chemical industry and, in addition, there is an irreversible trend towards digitization of processes and information to help managers, engineers, and crew members keeping it safe.

In this scenario a real-time monitoring system, called Dynamic Risk Advisor (DRA), was developed combining two different methods of risk assessment (LOPA and Bowtie), aiming to evaluate the integrity of three barrier classes, which are Physical, Organizational and Human. To perform this real time monitoring, DRA system integrates with other systems like MAXIMO (Maintenance Management; MOC System), DRAKE (Training Platform) and Supervisory System (F&G System, Thrusters, sensors etc.). Using all data from those systems, was created a specific Performance Standard, criteria for barrier degradation and was stablished the acceptable frequencies of unsafe events based on the ALARP (as low as reasonably practicable) approach.

The frequencies of threats, hazard scenarios and its consequences shown in DRA screen are calculated using the LOPA semiquantitative method. DRA has “Dynamic” in its name because it automatically calculates the residual risk based on barriers’ health in real time. Furthermore, the Bowtie layout exhibited in DRA provides an easy-to-understand overview of implemented barriers and its integrity. This tool was designed to help both managers and entire process-related workforce to find safety vulnerabilities, prioritize preventive and corrective actions and manage the processes risks.
