Riser Weld Pre-Service Inspection

Riser_PreRisers are critical components in the upstream segment of the oil & gas industry. A riser weld supports huge internal constraints and their integrity is critical for secured, ongoing operations.

Rise Weld Inspection Challenges

In the past, newly manufactured riser welds underwent an x-ray process. Normally the weld area had to be evacuated for the x-ray process or in-production risers were moved to a remote location for safer radiation use. The HES constraints linked to the use of RT techniques pushed the industry toward ultrasonic inspection.

Recommended Solution & Advantages:

A combination of TOFD and Phased array has become the industry standard technique for inspecting welds on risers. It requires well trained technicians but allows the production environment to remain as lean as possible since there is no requirement to evacuate the welding area or moving the in-production riser to a remote location.

Improved productivity

  • Lean process not requiring area evacuation or part movement to perform the x-ray
  • Quick and solid setup – no need to rescan weld due to the wrong parameters being entered, wrong probe positioning, un-calibrated group

Better probability of detection

  • TOFD and Phased Array
  • Advanced techniques like tandem
  • Less rejects due to more advanced analysis tools
  • Merge view
