Tool Verification

Home - What we do - Activities - ILI qualification - Tool verification and field valudation (2)1

Correlation of magnetic flux leakage ILI signals with actual metal loss on the pipeline presents difficulties when a high concentration of metal loss features or complex shapes of metal losses are encountered.

Both scenarios are known to introduce location and sizing errors due to inherent limitations of magnetic flux leakage technology. As a result, distance based correlation may prevent accurate determination of true ILI performance.

The LaserSure™ process was developed to employ pattern matching techniques, aligning ILI features with actual metal loss measured from laser profilometry to improve the accuracy and reliability of correlations.

Through the LasureSureTM software, we can achieve the following:

  • Identify metal loss anomalies above a specified threshold
  • Confirm ILI anomalies position and dimensions
  • Accurately calculate burst pressures

Compliance with API 1163

In-ditch verifications are required to determine if the ILI tool performance should be accepted, rejected, or adjusted depending on the in-ditch verification measurements, as suggested in the 2013 ILI Systems Qualification Standard, API 1163. However, some ILI assessments report only metal loss anomalies that are not severe enough to warrant excavations for repair. Using methods described in the API 1163 Second Edition, data other than from in-ditch examinations can be used to make a decision to accept, reject, or adjust the reported results from an ILI tool run.

When metal loss anomalies are not very severe, it is often acceptable to use a Level 1 performance measure which can rely on measurements for similar ILI runs or vendor specifications without significantly increasing the probability of failure for a pipeline segment.
