Abstract
This review paper thoroughly investigates the challenges associated with constructing polar icebreakers, given the increasing feasibility of Arctic navigation attributed to global warming. The strategic significance of the Northern Sea Route in global trade, potentially reducing the Asia-Europe transit distance by about one-third, underscores the growing importance of polar-class vessels in Arctic navigation. Our research emphasizes the importance of selecting suitable steel grades considering strength, toughness, and weldability. The paper investigates the influence of ductile-brittle transition temperature on ship failures and evaluates different marine steels' tensile properties and fatigue behavior. Additionally, it reviews welding techniques and explores advanced methods, including wire arc additive manufacturing, to improve precision and efficiency in shipbuilding.

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
