API 510 Pressure Vessel Inspections

Whether you're undertaking a complete API 510 inspection on a time interval or looking to conduct just one portion of your Risk Based Inspection (RBI) program, Gecko’s inspection services are tailored to your objective.   

Certified API inspectors conduct external, internal and on-stream inspections, augmented by our Level II/III NDE/NDT technicians providing wall thickness and defect detection.  This service is anchored by our RUG, Rapid AUT and Phased-Array UT robots.  

The major benefits of inspecting with Gecko are

  1. Complete coverage in 1-2 shifts without the need for roping, scaffolding or JLGs
  2. Fast RUG and Advanced Ultrasonic inspections suitable for on-stream inspection in lieu of internal.
  3. If we do an internal, we can perform CUI from inside the vessel.

Across the plant, many assets fall under the API 510 Pressure Vessel Inspection Code.  Equipment such as butane spheres, bullet and chemical tanks must be inspected to meet these requirements.  Our API 510 inspection service is designed to slot into a plant’s current inspection plans, whether you need to fulfill a specific inspection or need to construct an entire program from the ground up taking RBI and best practices into mind.

The process stems from your inspection plan.  If no plan already exists, we’ll consult with you to learn your approach to mechanical integrity.  This starts the process by understanding the nature of the pressure vessel, its operating history and likely damage mechanisms.  This is the basis for establishing the inspection timeline. Your plant may be using a broader RBI program, in which case, we’d include the risk factors associated with the asset to hone our inspection approach.  If a plan already exists, Gecko can perform your external visual, internal, thickness or on-stream inspections as needed.

Because Gecko can provide high resolution thickness measurements via its Rapid Ultrasonic Gridding (RUG) technique and defect characterization with its Phased Array UT systems, our services have been shown sufficient to replace internal inspections or lengthen the inspection interval within RBI programs due to superior data quality and completeness of coverage.


Written reports, prepared by our API certified inspectors, are supplied to the client along with access to our online portal, Gecko Portal, that provides interactive mapping of all thickness measurements.  This allows for annotation, export, and sharing for maintenance planning.

Each report includes these sections - 

  • Executive Summary
  • History Review
  • Recommendations and Recommended Next Inspection
  • Report
    • Component summaries
    • Detailed Report
  • Inspection Photos
  • Construction Drawings
