Port of Brownsville Floating Breakwater
Bibliographic record
Abstract
The present paper describes the technical aspects of a new floating breakwater concept that was installed at the Port of Brownsville Marina located in Port Orchard Bay, Washington State, in 1999. The breakwater incorporates submerged porous treated timber "wave fences" installed on either side of the concrete pontoons to reduce wave transmission. Eight concrete pontoon units are connected to each other by a patented rubber cushion shear tube and bolt assembly on each side of the pontoon, and are held in place with steel anchor piles. A numerical model based on an eigenfunction expansion method was developed to study floating breakwaters equipped with pairs of wave fences of different porosity. A physical model test was conducted to study the performance of the breakwater under the action of oblique waves. A structural model was used to compute the design force envelopes for the concrete floats, using transient wave loads from the model studies as input. The unique solution developed in this project provides a cost-effective option for coastal and marina protections using floating breakwaters.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
