Abstract
This work aims to provide further insight into the modeling aspects and influence of some important parameters involved in the simulation of vibration of submerged pipes, especially in relation to vibrationbased structural health monitoring (VB-SHM) techniques.Two widely used techniques for modeling submerged pipelines, namely the "added mass" and "coupled acoustic-structural" approaches are compared, and their limitations and advantages in the context of VB-SHM are highlighted.Moreover, the paper also presents a comprehensive study of the effect of operational variability on the accuracy of VB-SHM of offshore pipelines.It is demonstrated that the geometric stiffness produced by the operational variability (such as changes in the internal and external pressures of pipelines) could variably alter the overall stiffness of such submerged bodies, hence affecting their dynamic response.Depending on the pipe stiffness, the imposed variations could significantly affect the accuracy of VB-SHM trials.A list of symbols can be found on page 121.

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.
