ENVIRONMENTAL WAVE DATA FOR DETERMINING HULL STRUCTURAL LOADINGS
A survey evaluation is given of observed and measured wave data covering major U.S. routes, with appendices, tabulations and maps. The introduction of theoretical formulations leads to the discussion and evaluation of wave spectral hindcasting techniques. The methods used to predict ship motions and loads are explained followed by a section discussing the wave data format required for predicting short and long-term loads and motions as well as numerical examples showing the effect on and sensitivity of predictions to variation in wave data format. Based on the preceding discussion, presently available data suggested for use in determining ship loads are given. The use of a combination of statistics based on observations on the frequency of occurrence of various wave heights and a spectral family of measured spectra grouped by wave height is recommended. Finally, a survey of current and planned data collection projects is given.
