Whole-Ship Motions of USCGC Healy as Applied to Global Ice Impact Forces
Bibliographic record
Abstract
Providing the whole-ship motions in ice operations was part of the Canadian contribution to the Arctic Ship Technology Research and Development Program conducted on the USCGC Healy. An inertial measurement system was used to measure the whole-ship motions of the USCGC Healy during its Ice Trials, April/May 2000. The system provided time-series traces of ship motions in six degrees of freedom. A variety of loading conditions was sampled, ranging from relatively light ice conditions to backing and ramming in pressured first- year ice and multi- year ice. The ship motions experienced under the different ice conditions ranged from pitch angles of 0.2° to 0.8° and roll angles of 0.6° to 4.9°. A representative case in which the ship rammed a first-year ridge in open pack ice is discussed. During that event, the ship experienced a 0.7° pitch and 4.9° roll. The whole-ship motions during the ridge impact were used to estimate a vertical bow force of 4.3 MN.

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.
