Piping freelance

As a dedicated process operations, commissioning & start-up Engineer with over 15 years of international experience, I specialize in delivering safe and efficient commissioning operations Currently, I lead commissioning activities for the Arctic LNG2 project in Russia, where I oversee critical systems including hot oil, fuel gas, glycol-water systems, and flare networks for LNG production trains utilizing Linde MFC® technology. Throughout my career with industry leaders like Technip Energies and major refineries, including Middle East Oil Refinery (MIDOR), I've developed a proven track record in: * Developing and executing Operational Test Procedures (OTPs) and P&ID markups. * Managing complex SIMOPS environments between construction and operations teams. * Validating Safety Instrumented Systems (SIS) and implementing robust Permit-to-Work systems. * Leading troubleshooting efforts for process systems and equipment performance issues. * Mentoring operations personnel and ensuring seamless handovers to steady-state operations. My technical foundation includes deep knowledge of LNG liquefaction processes, refinery operations (particularly delayed coker unit), utility systems, and environmental facilities, including wastewater treatment. I pride myself on bridging the gap between complex engineering designs and practical field execution while maintaining uncompromising safety standards. I'm passionate about contributing to energy projects that power our world responsibly and efficiently. Open to connecting with professionals in the oil & gas, LNG, and petrochemical sectors for knowledge sharing and potential opportunities that leverage my commissioning expertise on challenging global projects.
