Abstract

fetched live from OpenAlex

Structural design has been shown to be an effective tool for reducing collision damage and cargo spill of a struck oil tanker given a collision. This paper explores the structural redesign of a double-hull oil tanker side-shell in order to improve its collision performance with respect to hull rupture, damaged area, and oil-outflow. In particular, the side-shell plate stiffening arrangement and transverse web frames are redesigned, with weight and structural capacity as design constraints. Explicit-dynamics numerical models using LS-DYNA show that reducing the structural rigidity of the tanker's side-shell, while maintaining the same plate stiffening steel weight may: increase the efficiency of the side-shell in converting kinetic collision energy into elastic strain energy; reduce the longitudinal and overall damaged areas; and 'compartmentalize' the damage so that residual stresses decrease quickly with radial distance from the point of impact.

Teacher imitation

Not 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.
