Abstract
Large shiploaders that transfer bulk materials are one of the most critical components of a bulk materials handling port. Any disruption in a shiploader service can cause major interruptions in port operations. The design of shiploaders is covered in a few mobile and semi-mobile equipment standards that are limited in scope and clarity regarding seismic design. To compensate for the limited scope of the mobile and semi-mobile equipment standards, design engineers revert to building codes that are created for human-occupied spaces. Building codes are not suitable for the seismic design of shiploaders as they ignore the shiploaders’ ability to move and rotate. Applying the seismic design rules of building codes to shiploaders will result in a significant uncertainty. In this paper, a case study is presented to highlight the importance of performance-based seismic design for shiploaders. The analysis and design approach that implemented the use of seismic structural fuses to control the structural response to earthquakes are explained. The need for integrating the superstructure with the foundations to simulate the soil-structure interaction is highlighted. The study concluded that the proper modelling of certain mechanical components is essential to simulate their true behaviour during an earthquake.

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
