Effective risk management is critically important for Engineering, Procurement, and Construction (EPC) projects in the petrochemical industry, given their complex, capital-intensive, and high-risk nature. Traditional methods like Failure Mode and Effects Analysis (FMEA), despite their widespread use, suffer from limitations such as equal weighting of criteria and an inability to handle large volumes of risks efficiently. To bridge this gap, this study proposes a novel hybrid framework for the systematic identification, assessment, and prioritization of risks. The proposed model integrates the core FMEA approach with the Best-Worst Method (BWM) for determining optimal weights of Severity, Occurrence, and Detection criteria, and the Combined Compromise Solution (CoCoSo) method for precise risk ranking. A key innovation is the incorporation of the K-means clustering algorithm, which uncovers hidden patterns and groups risks with similar profiles, providing managers with a holistic view for developing integrated mitigation strategies. The framework is applied to a real-world case study in Iran's petrochemical industry involving 123 identified risks across eight dimensions. Clustering results reveal five distinct risk clusters, facilitating focused attention on critical areas. Furthermore, the final CoCoSo ranking identifies the most significant risks in domains such as knowledge management from past projects, price volatility of equipment, and integrated information management. This integrated framework serves as a strategic tool, enhancing the capability of EPC project managers in optimal resource allocation and effective response planning for complex project risks.
