Our inspector will visually examine these assets and compare them to documented equipment drawings and previous inspection reports (if no formal documentation is available, OGL creates them for you). The inspector makes note of any areas of concern, and depending on the findings, may recommend more advanced techniques to determine the damage’s scope.
In addition to traditional visual testing, OGL also offers borescope and remote video testing services, which are video tools that can be used to visually inspect asset interiors and those in hard-to-access locations.
Visual testing (VT) Inspection Standards
Among others, OGL provides visual inspection services to the following industry standards.
- American Petroleum Institute (API)
- API 653 Above Ground Storage Tank Inspection
- API 510 Pressure Vessel Inspection
- API 570 Piping Inspection
- API 579 Fitness for Service
- API 580 Risk-Based Inspection
- API 936 Refractory Inspection
- ASME Boiler & Pressure Vessel Codes
- SNT-TC-1A & CP189
- American Welding Society
- Certified Weld Inspector (CWI)
Visual testing is used in all industries and at every step of a component’s lifecycle. VT can easily find and evaluate the following discontinuity types:
- Cracks
- Holes
- Corrosion
- Blisters
- Impact damage
- Most other discontinuities that are surface-breaking or result in deformation at the surface
