Underwater application of structural health monitoring at Fairview Cove Container Terminal
Bibliographic record
Abstract
To be able to offer services to the world's largest container vessels, commonly known as Post-Panamax vessels, the Halifax Port Authority launched a dredging project to increase the berthing depth at its Nova Scotia facility. To monitor the movement of the existing pier during and after construction, sensors were installed in the sub-sea foundation 14 m below mean sea level. Vibrating wire strain gauges were attached directly to steel sheet piles (positioned adjacent to the existing concrete cribs) and both Bragg grating and Fabry-Perot fibre optic sensors were attached to anchor bolts used to attach the sheet piles to the cribs. Strain monitoring over approximately an eight month period indicated that the sub-sea shoring of the crib foundation has become engaged to resist the slight settlement of the cribs. The resulting stresses are very low, however, confirming that the cribs are performing well within design and functional limits. The project also confirmed the durability and effectiveness of the use of fibre optic sensors in marine environments.

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.
