Summary

Wave loading of ships and maritime structures is a random process and the response of these structures is itself a random process. Much work has been undertaken to better understand the nature of waves and a number of existing techniques are described. Statistical and spectral analysis techniques may be used to quantify the wave loads and the corresponding structural responses. The relationship between the input load and response may then be determined through the use of response amplitude operators and the response of the structure to predicted lifetime extreme loads and fatigue loading then calculated. Standard wave spectra and directional spreading factors are used to enable the seaway to be described mathematically and several standard forms are discussed. The use of statistical methods enables the seaway to be described in terms of a limited number of parameters from which short term and long term probability distributions may be obtained. These distributions may then be used to enable extreme lifetime loads to be estimated. ysis of non-line oe@
