dc.description.abstractThis study presents a novel risk assessment approach for crude oil heaters, integrating structured combined methods to enhance safety and reliability. We begin by employing Hazard and Operability Study (HAZOP) to systematically identify potential accident scenarios. To deepen our understanding of system functionality and potential malfunctions, we utilize D-higraphs for functional modelling. Building on the scenarios identified, we apply Fault Tree Analysis (FTA) to estimate root causes and frequencies of failures. Following this, Event Tree Analysis (ETA) allows us to explore the consequences of success or failure of safety barriers. The integration of FTA and ETA culminates in the bowtie method, which effectively illustrates the relationships between hazards, their causes, and the safety measures in place. This structured methodology not only offers a comprehensive risk assessment framework but also enhances the identification and evaluation of safety barriers, making it a unique contribution to existing risk assessment practices.
