Genetic-Algorithm-Based Method for Ship Extreme Behavior Assessment…#169;
Within the past decade, the need for reliable extreme wave climate data has increased significantly as a consequence of increased ship and offshore object development. It is important in the design of all marine structures to be able to withstand extreme environmental loadings. Typically,
a structure must be designed to withstand, within a margin of safety, an exceeded degree of wave loading that is expected only once every 50 to 100 years. In order to achieve this, the concept of a random process extreme value must be examined. The process of extrapolation plays a fundamental
role in this area of analysis, and it is therefore essential to empirically fit a convenient probability distribution that describes the available data as closely as possible. Estimation of extreme values probability distribution parameters by genetic algorithm is applied to improve the methodology
of extreme values prediction. Illustrative applications of the method are given for a North Atlantic sea environment. The results are presented as crest height maximum values occurring with a given probability, or in a design storm that has a specified return period. The time series of ship
response at the most severe storm conditions within the last 50 years are given.…#169;
