Evaluating the performance of the Korean research icebreaking vessel “Araon” in ice
Bibliographic record
Abstract
The Institute for Ocean Technology of the National Research Council of Canada has conducted a series of resistance, propulsion and manoeuvring tests on a scale model of the Korean icebreaker Araon attached to a Planar Motion Mechanism (PMM) and in a self-propelled test configuration. Investigation of the Araon’s podded propulsors and their influence on ice-hull load distribution were conducted in open water and level ice, pack ice, ridges and rubble. The tests included straight, zigzagging, and circular runs with control over propeller shaft speed and pod angle in both configurations. Ice loads, model position, pod performance characteristics and ice-hull pressures were monitored during these tests. From these measurements the full-scale icebreaking, manoeuvring, and propulsive capabilities can be predicted and compared with the ship’s actual performance. The tests were used as a study of the hull form’s clearing ability as well as the loading it experiences from encountering ice during different manoeuvres.

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.
