Abstract

fetched live from OpenAlex

Abstract Computer modelling is a common approach used to understand personnel safety and pipeline integrity risks impacting pipelines near high voltage AC power lines. A modelling approach often relies on the timely availability of accurate power line data from electric utilities to incorporate into simulation software. Long lead times for power line information requests, however, can often leave operators with assets in a prolonged high-risk state. This paper presents an AC mitigation case study wherein generic; shovel-ready AC mitigation grounding and corrosion monitoring systems were applied across a large pipeline system in Alberta, Canada. These systems were installed wherever AC pipe-to-soil potentials were encountered above a set threshold. A computer model was later developed to look for possible performance gaps and identify areas for mitigation supplementation. The case study demonstrates that a correctly deployed direct-to-install approach can be highly effective at reducing steady-state interference risks but can leave gaps due to the limitations of what can be measured in a field setting. Computer modelling is shown to be an effective means of bridging these gaps to ensure that all personnel safety and pipeline integrity risks are mitigated.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
