Methods of Extreme Value Estimation in Seakeeping Analysis

An important parameter regarding operability and structural safety of ships and offshore objects is its extreme response at heavy environmental conditions. One of the most critical features of the design process is the estimation of the worst condition to which a given structure is likely to be exposed in its lifetime, and in particular the prediction of a characteristics value which is associated with the certain probability of nonexceedance in that time. In order to achieve it the concept of a random process extreme value must be examined. Illustrative applications of the methods are given for a North 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.
