Review and approve EPC contractor detailed engineering deliverables, technical queries (TQs), design deviations and Management of Change (MOC) requests. Participate in detailed HAZOP studies, 3D model reviews, design reviews and constructability assessments. Verify integration of process systems across hydroprocessing units, tank farms, utilities, marine loading facilities and sulphur handling systems. Witness Factory Acceptance Tests (FATs) for critical process packages, where required. Review and approve commissioning, pre-commissioning, start-up and operating procedures, and support performance testing, troubleshooting and final handover. Ensure compliance with applicable API, ASME, IEC 61511, Shell DEP or equivalent standards, project specifications and relevant environmental and social requirements. Safeguard process safety, operability, maintainability and long-term asset performance in line with the intended 40-year design life. Provide authoritative technical guidance to project management, engineering teams, contractors, licensors and other stakeholders throughout the project lifecycle. KEY QUALIFICATIONS: Bachelor's degree in Chemical Engineering; a Master's degree in Chemical Engineering or a related discipline is preferred. Minimum 15 years of relevant process engineering experience in oil and gas, refining, petrochemical or related process industries. Minimum 8 years in senior, lead, managerial or process technical authority positions. Demonstrated experience across the complete Pre-FEED, FEED and EPC project lifecycle. Owner's Engineering or Project Management Consultancy (PMC) experience is strongly preferred. Proven technical expertise in hydroprocessing, particularly hydrodesulphurisation (HDS) or hydrotreating.
