Abstract
The paper describes the instrumentation used for the measurements of various parameters of interest for a gravity based structure type offshore platform during its set-down model tests. The tests were conducted at the wave basin facility of National Research Council of Canada (NRC). The parameters of interest included motions of the model in six degrees of freedom, parameters describing the environmental conditions such as wave elevations on selected locations in the wave basin, inflow rate of the ballast water and the water levels in the ballast tanks as a function of time, all synchronized. The complexity of the instrumentation arose due to the need to model both external dynamics, i.e. motions, and internal dynamics, i.e. the dynamics of the ballasting operation. The set-down operation was simulated in different wave conditions. During the tests the motions of the model as it was lowered to the sea floor by the ballasting operation were measured by two different systems. The first one is a motion capture system, which uses cameras and associated software to determine the motions of the model. The second system consisted of an array of accelerometers and digital inclinometers installed inside the model. During the set-down tests the flow into the central compartment inside the model for ballasting operation was controlled by a peristaltic pump. It allowed start/stop/pause on command and ease of change of flow rate. Two associated parameters were recorded by the data acquisition system (DAS): pump-on-off and flow rate. The water collected in the central compartment was eventually distributed into the surrounding ballast compartments during operation. Each compartment was instrumented to record the water levels as a function of time. Synchronization of the data enabled locating and investigating specific events recorded by the DAS.

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
