Abstract
A method is developed to predict the time series of the wave exciting moment per unit virtual mass moment of inertia using the stationary random roll response. The estimated variance and autocorrelation function of the excitation are compared with those obtained using numerically generated data. The agreement is excellent. The method was also applied to experimental data obtained using two ship models. The predicted autocorrelation function for the excitation was compared with the autocorrelation function of the wave height. The method predicts the form of the autocorrelation function accurately. The method lends itself to use aboard ships at sea without interrupting the mission of the ship. Results of this analysis can help in planning optimum ship routing.
