Background and issues
The GADline software tool is used to reach a decision on the acceptability of the defects detected and sized on a gas transmission pipeline, on the basis of the mechanical strength criteria in the GAD (Defect Analysis Guide); it is thus a decision-support software program for the maintenance of infrastructures.
Specifically, the GADline software is used to analyze:
- The acceptability of anomalies (corrosion, scratches, geometric deformations, combined defects, etc.) found during a piston-based inspection or after an on-site characterization;
- Time-dependent changes in the acceptability of the corrosion indications vs. the kinetics of the phenomenon.
