Abstract
Pitting corrosion under insulation is one of the challenging issues for safe operation of offshore facilities. Degradation usually remains hidden causing the inspection of insulated assets to be equally challenging. The modeling of the pitting corrosion under insulation (CUI) helps us to better understand the current state of the asset and predict failure. This paper investigates the factors affecting the pit initiation and pit growth on equipment under insulation operating in offshore environments. A methodology is proposed for studying the pitting CUI characteristics, including pit initiation time, pit density, and maximum pit depth over time. The proposed methodology provides a practical and more effective asset life management approach when supported by inspection data. The practical application of the proposed methodology is demonstrated in this paper using a pressure vessel case study in an offshore platform.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
