  Technip Energies

  Oct 2021 - Jul 2023

  Senior Engineer -Instrumentation & Control system

  As a Senior Instrumentation Engineer at Technip Energies, I played a key role in leading instrumentation design and execution for major offshore projects, such as Qatar’s Al Shaheen field. My responsibilities included specifying and accurately sizing essential instruments—thermowells, control valves, analyzers, and flow meters—using advanced software tools like Instrucal and SPI to ensure they met high standards for performance and safety in demanding offshore environments.My role also focused on risk management, where I actively participated in HAZOP meetings and conducted Safety Integrity Level (SIL) assessments to identify and mitigate potential risks early in the process. This proactive approach reinforced safety at every project stage, aligning with Technip’s dedication to maintaining the highest industry standards.Collaboration with multidisciplinary teams across engineering, project management, and construction was central to my work. I oversaw Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) to verify the systems’ readiness and compliance with client requirements. By emphasizing continuous improvement, I integrated project feedback to enhance our practices and foster a culture focused on innovation, quality, and safety. My efforts supported Technip’s commitment to delivering robust, sustainable engineering solutions that anticipate future industry needs. Show less
