Resistance, self-propulsion and wake survey tests of the Preliminary Design (Model IOT907) of DND Joint Support Ship
Bibliographic record
Abstract
This report describes the experiments carried out on a 1:29.69 scale fully appended model of the Preliminary Design of the Joint Support Ship (JSS) in the Oceans, Coastal and River Engineering (OCRE) Towing Tank in November - December 2011. The purpose of these experiments was to evaluate the performance of this revised design of the JSS in terms of its resistance, propulsion and wake survey characteristics. Appended resistance experiments were done at three conditions. Condition1 represented the End of Life (8.2 m draft) condition. Condition 2 represented the Deep Departure (8.0 m. draft). Condtion 3 represented End of Life with trim by bow. Effective Power at 20 knots is 10.4-10.5 MW. Self-propulsion experiments were done at Condition 1. Delivered Power at 20 knots is 15.9-16.3 MW. Wake Survey experiments were done at speeds of 15 and 20 knots. Both of the wake surveys showed poor flow into the upper half of the propeller disc.

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; a candidate call from one teacher head, not a consensus.
