Full scale experience with Kulluk stationkeeping operations in pack ice (with reference to Grand Banks developments)
Bibliographic record
Abstract
This report addresses the question of moored vessel stationkeeping operations in pack ice, on the basis of full scale experience with the Kulluk in the Beaufort Sea. As part of this work, a data base which documents full scale ice load levels on moored vessels has been significantly extended, and now includes almost 700 individual ice loading events. In addition, more operationally oriented information about ice management support activities and levels of risk (alerts) has been blended with the load data, for each event. Various scatter plots of expected ice loads in managed pack ice conditions are presented. Data relating to the effect of different levels of ice management support on load and risk levels is also included. The implications of this information are outlined in relation to various moored vessel system operations in Grand Banks pack ice conditions. It is shown that moored vessel operations in the type of pack ice conditions periodically encountered on the Grand Banks should be less difficult than is currently perceived, provided systems with reasonable in-ice capabilities and adequate levels of ice management support are used.

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; both teacher heads agree on what is shown here.
