Testing of evacuation system models in ice-covered water with waves
Bibliographic record
Abstract
A series of experiments was carried out to study the navigability of three evacuation lifeboat designs in a variety of environmental conditions. The test series investigated the combined effects of ice and waves on the lifeboats. Three different hull designs representing current lifeboats were modelled at a scale of 1:13. The variables in the test program included the hull design, level of power to the model, ice concentration, wave period and model launch direction. The lifeboat had to meet pass/fail criteria, which depended on whether the model could make way in a given environmental condition. Overall, the models were able to make way in most cases. Compared to previous evacuation model test series, the models in the present tests were better able to navigate the given conditions. When travelling with the wave direction, the model could always make way. When travelling into the waves, the models all had some difficulty in several tests; especially those at higher wave frequencies and higher ice concentrations. The results provide further insight into the viability of evacuation lifeboat systems in ice-covered water conditions.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
