Risk Analysis of Offshore Test Process for Ultra High Temperature and High Pressure Wellhead Equipment System Based on FMECA

Abstract

The wellhead equipment system is crucial for the safety and efficiency of offshore oil and gas operations. However, the offshore testing process for such systems involves significant risks that, if not adequately managed, may lead to catastrophic failures. This study employs Failure Mode, Effects, and Criticality Analysis (FMECA) to systematically identify, assess, and prioritize potential failure modes during the offshore testing of ultra-high-temperature and high-pressure wellhead equipment. By integrating historical failure data, expert judgment, and quantitative risk assessment, a comprehensive risk analysis framework is developed. The results highlight the most critical failure modes, their potential impacts, and corresponding mitigation strategies. This research provides a robust methodology for enhancing the safety and reliability of offshore wellhead equipment testing, thereby reducing operational risks and preventing environmental disasters.
