A method, called spectral response surface method, is proposed for the study of the ringing phenomenon of offshore structures. Newman's results for diffraction force on a column were reformulated in terms of the frequency components of the ocean surface and their hilbert transforms. Using a first-order reliability method together with adynamic model for the structural response, it is sraightforward to calculate the ocean surface history most likely to generate an extreme ringing response and the ringing response history.
