Coated Pipes for Blind Testing of ARTEMIS

May 26, 2020

Blind tests have been performed on several corroded spool pieces with ARTEMIS, with exciting results.

Challenge

  • A major operating company prepared four spool pieces for blind testing
  • All spool pieces contain corrosion features and are coated with a shrink wrap field joint coating
  • Prior to coating all of the pipes have been inspected using a standard AUT inspection method
  • Full Data on one of the spools has been supplied as a reference for the inspection
  • The pipes have been shipped from the PRCI pipe store in Houston to the Halfwave laboratory in Portland UK.

Sample Pipe Details

  • Pipe diameter: 16” OD
  • Pipe length: 1000 mm
  • Pipe thickness: 0.500” (12.7 mm)
  • Pipe material: X52 and X60
  • Shrink wrap type: Canusa PP or PE heat shrink wrap
  • Coating thickness: 2.3 – 2.5 mm

 Solution

The pipes have been inspected using the Halfwave tank facility and using the ARTEMIS system

Result

  • Client advised that all defects were identified and sizing expectations were met

Conclusion

​ARTEMIS has provided data measurement quality on par with existing automated ultrasonic systems without the need for field coating removal. The operator selected the ARTEMIS in-field subsea inspection with results that well exceeded expectations for flexibility, quality and accuracy. A new and valuable tool has been added to the industry’s toolbox for pipeline integrity assurance!
