“…It should be noted that the group structure cannot arise in a linear wave field described by equation ( 6) and has a strong dispersion [14]. The group structure can arise only due to the nonlinearity of wave processes [15,16], including due to the Benjamin-Fair instability [17,18].…”

The variability of the group structure sea surface waves is analyzed by numerical simulation. The analysis is carried out on the basis of an analytical model that describes the group structure of nonlinear waves. The characteristics of the wave group are controlled by two parameters, the group height factor (GFH) and the group length factor (GLF). With a fixed wave energy, the maximum wave height is determined only by GFH and does not depend on the GLF. It is shown that if GFH varies from 0.1 to 0.9, then at a fixed wave energy, the maximum wave height in the group increases by one and a half times. As the GLF increases, the number of high-height waves successively affecting the ship increases.
