Journal of Offshore Mechanics and Arctic Engineering 126 (4) : 337-345. ScholarBank@NUS Repository. https://doi.org/10.1115/1.1834623 | Abstract: | Instead of a Volterra-series based method, a method based on Price's theorem and Fourier Transforms is proposed for evaluating the nonlinear response power spectra of fixed offshore structures modeled as finite-memory systems. The numerical computation effort required for spectral estimations using the proposed method is significantly less than that of the Volterra-series method that requires multi-dimensional integrations. Nonlinear frequency-domain analyses of two jack-up platform structures are carried out to study the effects of inundation, cubic and quartic drag terms and polynomialization methods.
