• Conduct detailed system and vessel inspections (mechanical integrity, hygienic standards, and cleanliness), ensuring alignment between as-built systems and design specifications.
• Troubleshoot and resolve complex technical issues, including misalignments, leaks, control instabilities, and equipment or instrumentation faults.
• Ensure all shakedown and commissioning activities are executed in accordance with GEP requirements and site safety procedures, including COHE/LOTO where applicable.
• Coordinate closely with Automation Engineers (e.g. DeltaV/PLC) to support interlock testing, I/O verification, and alarm functionality during system start-up.
• Interface with Utilities, HVAC, vendors, and construction teams to ensure effective integration and issue resolution across system boundaries.
• Support commissioning documentation, including test records, punch list management, and system turnover packages to C&Q teams.
• Provide technical support and guidance to junior engineers and technicians during commissioning and shakedown activities.
• Support deviation resolution, field changes, and issue tracking to ensure systems are delivered in line with project timelines and quality expectations.
