Overview
Perform third-party inspection of pressure vessels during shutdown or turnaround activities at Ras Laffan Industrial City. Ensure compliance with API 510, ASME Section VIII Division 1 & 2, and client specifications. Witness and review all inspection activities, evaluate fitness-for-service (FFS), and issue comprehensive inspection reports to safeguard asset integrity and regulatory compliance.
KEY DUTIES & RESPONSIBILITIES
Inspection Execution
- Perform internal and external visual inspection of pressure vessels to identify corrosion, erosion, cracks, blistering, mechanical damage, and high-temperature hydrogen attack (HTHA).
- Execute thickness measurements (UT scanning) to determine remaining life and corrosion rates.
- Identify and document locations requiring further NDT or remedial action.
NDT Witnessing & Review
- Witness and verify all Non-Destructive Testing activities including:
- UT (Ultrasonic Testing) – thickness, shear wave, phased array
- RT (Radiographic Testing) – film interpretation and digital
- MT (Magnetic Particle Testing) – surface and sub-surface defects
- PT (Dye Penetrant Testing) – surface-breaking flaws
- Review NDT reports and ensure techniques, procedures, and personnel certifications meet applicable codes and client specifications.
- Challenge unacceptable NDT results and request re-testing or alternative methods as necessary.
Repair & Welding Oversight
- Review and approve repair procedures, weld maps, and PWHT (Post Weld Heat Treatment) plans.
- Inspect weld preparation, fit-up, and final weld quality.
- Ensure all welding activities comply with ASME Section IX and client approved WPS/PQR.
Fitness-For-Service (FFS) Assessments
- Conduct FFS assessments per API 579-1/ASME FFS-1.
- Evaluate remaining life, maximum allowable working pressure (MAWP), and retirement thickness.
- Provide recommendations for continued operation, repair, replacement, or derating.
Documentation & Reporting
- Prepare and submit detailed daily inspection reports, final turnover packages, and punch lists.
- Document all defects, anomalies, and non-conformances with photographs, sketches, and measurements.
- Maintain accurate records of inspection findings and recommendations for client handover.
MINIMUM REQUIREMENTS
Mandatory Certifications
- Valid API 510 (Pressure Vessel Inspector) certification – mandatory and active.
Experience
- Minimum 5 years of hands-on pressure vessel inspection experience in the oil & gas industry.
- At least 2 shutdown/turnaround campaigns as a vessel inspector.
- Experience with hydrocarbon service vessels (separators, scrubbers, towers, reactors, heat exchangers on the shell side).
3.3 Technical Knowledge
- ASME Section VIII Division 1 & 2 – design, fabrication, and inspection requirements.
- API 571 – damage mechanisms affecting pressure vessels (HIC, SOHIC, HTHA, creep, fatigue, etc.).
- API 579 – fitness-for-service assessment methodology.
