Develop and maintain detailed commissioning plans, schedules, and procedures.
Review engineering designs, P&IDs, datasheets, and specifications to ensure commissioning requirements are incorporated.
Lead the commissioning of mechanical, electrical, instrumentation, and process systems.
Conduct pre-commissioning checks, functional testing, and performance verification.
Ensure all systems are commissioned in compliance with hydrogen-specific safety protocols and environmental regulations.
Prepare and maintain commissioning documentation, including test procedures, checklists, punch lists, and handover packages.
Supervise and coordinate commissioning technicians, contractors, and vendors.
Facilitate training and knowledge transfer to operations personnel.
Enforce strict adherence to hydrogen safety standards, site safety rules, and permit-to-work systems.
