Preliminary results of ship maneuvering in ice experiments using a planar motion mechanism
Bibliographic record
Abstract
Ship maneuvering experiments in ice are being conducted at the Institute for Ocean Technology (IOT) of the National Research Council of Canada. The aim is to provide a model test database for a subsequent mathematical and numerical modeling of the interaction processes between the ship and ice. The first phase of the experiments was carried out using a 1:21.8 scaled model of the Canadian Icebreaker, Terry Fox. The test program included straight resistance runs and turning circles maneuvers achieved by using a Planar Motion Mechanism (PMM) apparatus. In each experiment tow forces, turning moments, and ship motions were measured. In this paper, preliminary results of the experimental program are presented. The dominant ice-ship interaction processes are identified. The test results show large influence of ship motions and interaction geometry on the measured yaw moments. The geometrical aspect of the interaction processes is described and its influences on ice loads are discussed. Conclusions are made and recommendations for future works are provided.

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.
