Abstract
This paper investigates the restoring stiffness of the main platform concepts proposed for offshore floating wind turbine (FWT) systems; namely, barge, spar, tension leg platform (TLP). The overall system stiffness is partly due to the hydrostatics, and partly due to mooring. The hydrostatic stiffness matrix is formulated using the linear hydrostatic approach that assumes small platform rotation. A new analytical form of the mooring stiffness matrix for a taut-leg platform is presented and subsequently used to formulate the TLP mooring stiffness. While a numerical approach, is used for the other two platform types. The hydrostatic and mooring stiffness coefficients for the surge, sway, heave, roll, pitch and yaw degrees of the freedom (DOF) are computed for the different types of platforms. For each DOF, the magnitude of stiffness from both hydrostatics and moorings are compared.

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
