Enhancing Process Safety through Scenario Management
Joyce Miles, ExxonMobil Technology & Engineering
Expo A1
ExxonMobil utilizes a structured risk assessment process to manage process safety risks and reduce process safety incidents. With the goal of continuous improvement and through learnings from external benchmarking of our risk assessment and management processes, we identified an opportunity to further enhance our focus on low frequency higher consequence events through a scenario management process. Scenario Management helps keep major hazards and associated higher consequence potential scenarios top of mind and also demonstrates how potential significant process safety events can be prevented through the interconnected relationship of safeguards. At ExxonMobil, our Scenario Management process starts with identifying major hazards and the higher consequence scenarios associated with them, defines critical safeguards that prevent or mitigate those scenarios, and defines a process to manage those critical safeguards to keep them healthy. Scenario identification workshops were conducted for ExxonMobil’s chemicals, fuels, and lubes technology platforms. The technology-specific workshops highlighted the hazards and scenarios inherent to our process that have potential to lead to higher consequence scenarios and developed lists of standard scenarios for each platform. For the higher consequence scenarios, standard bowties were developed to further define the scenario and its critical safeguards. For each critical safeguard, performance criteria was developed to ensure each site was consistently assessing & maintaining safeguard health. This process helps ensures critical hazards and safeguards are known and effectively managed by our managers, supervisors, and team members.

With the goal of continuous improvement and through learnings from external benchmarking of our risk assessment and management processes, we identified an opportunity to further enhance our focus on low frequency higher consequence events through a scenario management process. Scenario Management helps keep major hazards and associated higher consequence potential scenarios top of mind and also demonstrates how potential significant process safety events can be prevented through the interconnected relationship of safeguards. At ExxonMobil, our Scenario Management process starts with identifying major hazards and the higher consequence scenarios associated with them, defines critical safeguards that prevent or mitigate those scenarios, and defines a process to manage those critical safeguards to keep them healthy.
