Estimating performance requirements for ships navigating to and from Voisey's Bay
Bibliographic record
Abstract
The Voisey's Bay nickel mine is located in Northern Labrador. To reach the mine site in winter requires a ship to navigate through a range of ice conditions. Close to the mine site, in the fjord, the ice is mostly uniform first year ice, up to 1.3 m thick. However, before reaching open water the ship must pass through broken ice, several layers thick, with different amounts of consolidation. This paper describes research carried out at the Institute for Ocean Technology, in support of the environment impact assessment, on behalf of Canadian Coast Guard, Newfoundland Region. The work fell into three distinct phases, which were full-scale trials on an icebreaker, model experiments on an icebreaker and model experiments on an ice breaking bulk carrier. The paper then identifies gaps in our knowledge of ship performance in typical Labrador ice conditions and the steps that must be taken to overcome them.

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.
