Pressure Vessel Inspector

Overview

Api 510

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

• **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

• – 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.
