Abstract

This paper presents a comprehensive study on hydraulic line modeling and pre-commissioning optimization for high-pressure, low-pressure, and corrosion inhibitor systems within subsea umbilicals. Emphasizing fluid dynamics, pressure loss mechanisms, and material considerations, the research develops accurate modeling techniques to predict hydraulic behavior under complex offshore conditions. It further explores optimized pre-commissioning strategies, including pressure testing, leak detection, flushing, and corrosion inhibitor injection, to ensure system integrity and operational readiness. Analytical insights reveal critical parameters affecting hydraulic line performance and demonstrate the benefits of optimized procedures in enhancing system reliability and reducing downtime. The study also discusses the implications of these findings for subsea umbilical design and maintenance practices, highlighting opportunities for improved material selection and monitoring technologies. Future research directions focus on real-time monitoring, advanced materials, and automated control systems to further elevate subsea system performance. The integrated approach proposed bridges design and operational challenges, supporting safer and more efficient offshore production.
