Effect of Padeye Depth on the Behavior of Offshore Anchor Piles Under Mooring Forces
Bibliographic record
Abstract
Offshore anchor piles are usually loaded at a padeye on pile surface. The padeye depth can be at the seabed or below it. Using a padeye below the seabed is widely used in case of suction caissons. However, anchor piles are more flexible and the mode of failure will be different from that for suction caissons. In the current parametric study, the effect of padeye depth on the behavior of offshore anchor pile subjected to mooring forces in dense sand was studied. Finite Element Model (FEM) had been established. The model had been calibrated based on the centrifuge tests that were carried out by the authors. Three piles of different soil-pile rigidity covering a wide range of pile flexibility were used in the study. The piles were pulled out at an angle of 15° to horizontal. In all cases the padeye depth was changed from at the ground surface to a depth of four times the pile diameter. From this parametric study, it was found that pulling out an offshore anchor pile at a level below the seabed has some advantages of increasing the ultimate capacity of the pile, decreasing pile deflection, and decreasing bending moment. An optimum depth of padeye was recommended.

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.
