Abstract
The ISO 19906 Arctic Offshore Standard (2010) represents a great advancement for standards as they pertain to Arctic engineering. However, uncertainties remain for a number of topic areas, including global loading on multi-leg structures in ice. These uncertainties include the effects of sheltering, the width of damaged ice and the effect of jamming. Additional uncertainties pertain to the effects of ridge loading and various ice properties. This paper numerically examines some of these uncertainties, through a parametric study approach. The results present the ice forces on a representative structure, as well as broken ice zone widths. The results show that peak loads are associated with ice drift at an angle, as observed in other laboratory and numerical simulations. In addition, loads increase with decreasing clearance between the legs. The results have applications not only for multi-leg oil and gas structures in ice-covered water, but could be further examined in the context of bridge piers and offshore fields of wind turbine towers.

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 it
