PR-453-134504-R02 Pipeline On-Bottom Stability Software Upgrade Milestone II
Bibliographic record
Abstract
The scope of work for phase I of PR-453-134504 included implementation of the Verley and Lund [1] clay soil model in Level 2 of the PRCI on-bottom stability (OBS) software. Throughout the implementation process, a number of apparent discrepancies between the code and the documentation in relation to the pipe-soil interaction (PSI) model were identified and raised with PRCI. In Phase 2 INTECSEA was tasked to formalize these observations and provide more background information to PRCI for further clarification. The execution strategy was to host a series of meetings with a focused group of PRCI team members to review various topics of soil model in Level 2 and prepare a technical note that captures the issues discussed. This document presents the technical note on the PSI topics and clarifies INTECSEA's suggestions for further work on this matter. A summary of the technical queries along with ITS recommendation is presented in Table 1-1. Further detail on each topic is available within the report.

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.
