AN ASSESSMENT OF REPRESENTATIONS OF LONG- AND SHORT-TERM OCEAN WAVE SPECTRA AND SHIP RESPONSE PREDICTIONS
This paper presents a review of the present method for predicting ship responses in a seaway. The applicability of the existing wave spectral representations for global ship response predictions are discussed, and problems associated with the extreme response predictions are illustrated. The study indicates that the errors induced by the use of different spectral representations are of the same order of magnitude as the errors generated from the other assumptions used in the prediction scheme.
