Abstract

Copyright © 2015 by the International Society of Offshore and Polar Engineers (ISOPE). Estimating the probability of a wave crest exceeding a given threshold is of fundamental importance in offshore engineering. At present second-order theory is used, with the Forristall distribution typically being used for this calculation. In this paper we investigate several points in connection with this approach. Firstly we examine some of the sensitivities involved in deriving second order statistics, including the high frequency cut-off, the directional spreading and spectral bandwidth. The paper then examines how the second order contribution varies for waves of different shapes. We investigate whether the NewWave can be used to predict the second order contribution to a wave-crest but find that the variation in wave shape is too great for this to be practical.
