✦ Synopsis

The wave height distribution with Edgeworth's form of a cumulative expansion of probability density function (PDF) of surface elevation are investigated. The results show that a non-Gaussian model of wave height distribution reasonably agrees with experimental data. It is discussed that the fourth order moment (kurtosis) of water surface elevation corresponds to the first order nonlinear correction of wave heights and is related with wave grouping.

In this paper a statistical methodology is extended to the nonlinear multi-degree of freedom vessel capsize problem in random seas. It is demonstrated that the study of transient motions, through analysis of the erosion of the vessel's safe basin mapped in the space of initial conditions [Soliman, M
