Abstract : The problem of nonlinear ship rolling is investigated by means of the method of equivalent linearization. For the case of rolling motion that is nonlinear in regard to damping (i.e. velocity square), it is shown that the spectrum of rolling in irregular beam seas at zero ship speed can readily be determined. A numerical example is given to illustrate the difference between the linear and nonlinear results. (Author)
