An independent-flow-field (IFF) model selected in this study to investigate the nonlinear response behavior of a medium-scale, experimental, submerged, moored structure is validated via parametric studies. Bifurcations in experimental responses are frequently observed, and the associated nonlinear primary and secondary resonances are identified in frequency response diagrams. Distinct from previous investigations, this study intends to identify a set of “best-fit” constant coefficients for predictions and comparisons over the entire wave frequencies examined. It is concluded that the small-body, IFF model predicts, reasonably well, the nonlinear, moored, and submerged structural response subjected to regular waves.
