Correlation of Inline and Aboveground Integrity Inspection Data for Comprehensive Pipeline Integrity Management Program
Bibliographic record
Abstract
Abstract Direct Assessment (DA), Inline Inspection (ILI) and Hydrostatic Testing (HT) are primary inspection tools acknowledged globally as approved pipeline integrity inspection techniques. These techniques have their merits and demerits, and each reflects a different, unique aspect of the overall integrity of a pipeline. ILI tools are designed to inspect the conditions of the pipeline wall with limited disruption to operations. These tools are used to identity and quantify the risk of corrosion, dents and cracks. However, ILI has a threshold for detection. DA is another pipeline integrity technique designed for the prevention of external corrosion in non-piggable pipelines, as well as piggable pipelines, where it can be used as a supplement to ILI. This technique is covered in ANSI(1)/NACE(2) SP0502-2010. Therefore, an integrated approach that combines ILI and DA techniques would provide a comprehensive pipeline integrity management program for pipeline operators. This paper provides comprehensive correlation of inline and aboveground pipeline integrity data geared at ensuring a complete pipeline integrity management program. Case studies are provided to show benefits of ILI and DA correlations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
