Experimental investigation on the statistics of rogue waves under a random wave background

Abstract

In this study, experiments on rogue wave events under a background of random waves were conducted in the wave basin. The improved method for generating rogue waves, introduced by Wang et al. (2015) was applied. The rogue wave event also satisfied the requirements of the specific spectrum and wave parameters, such as Hs, Tp and γ, through the wave calibration process. Wave statistical distributions were also analyzed and compared with the analytical and semi-analytical distributions widely used in practice, providing possible guidance for the generation of rogue wave events in random sea within a 3-h duration. Moreover, the study also shows the potential applications of this method in future seakeeping tests where the extreme wave-structure interaction needs to be considered.
