The nonlinear equation of rolling motion in random oblique seas is analysed considering parametric excitation caused by transverse stability variation in realistic seaway. Use of Bogoliubov-Mitropolsky’s method of slowly varying parameters together with Stratanovich-Khasminsky’s stochastic averaging is made to obtain an equation describing the variance of the amplitude of rolling motion as a function of time. The condition for stable motion is then derived. Furthermore, stationary variance is expressed in a closed form.
