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.

This report is a summary of a two-year project concerning the analysis of new and existing wave data and the evaluation of their effects on ship responses. The correlation of measured parameters, such as wave height and period, with surface log data, including but not limited to wind speed and observed height, is presented for Station 'India' as well as Station 'Papa', and a comparison of trends is given. A family of spectra based on wave height classification is presented as a proposed wave spectral data format most suitable for ship response prediction. The possibility of generalization of the spectral family is then discussed and a comparison is made with similar data from Station 'K' and 'P'. It is shown that differences in spectral shape between the three locations are minimal.

This monograph is an attempt to compile the present state of knowledge on ocean wave analysis and prediction. The emphasis of the monograph is on the development of ocean wave analysis and predic tion procedures and their utility for real-time operations and appli cations. Most of the material in the monograph is derived from journal articles, research reports and recent conference proceedings; some of the basic material is extracted from standard text books on physical oceanography and wind waves. Ocean wave analysis and prediction is becoming an important activity in the meteorological and oceanographic services of many countries. The present status of ocean wave prediction may be compar able to the status of numerical weather prediction of the mid-sixties and early seventies when a number of weather prediction models were developed for research purposes, many of which were later put into operational use by meteorological services of several countries. The increased emphasis on sea-state analysis and prediction has created a need for a ready reference material on various ocean wave analysis and modelling techniques and their utility. The present monograph is aimed at fulfilling this need. The monograph should prove useful to the ocean wave modelling community as well as to marine forecasters, coastal engineers and offshore technologists. The monograph could also be used for a senior undergraduate (or a first year graduate) level course in ocean wave modelling and marine meteorology.
