This paper gives the innovative methods to perform stochastic weather routing. Based on the information of the accuracy of predicted winds, waves and ocean currents, a method of estimating the standard deviations of passage time and fuel consumption on a particular route is described. By incorporating these standard deviations into the objective function, a method to perform stochastic minimum time/fuel routing is proposed. After showing the wind, wave and ocean current data of the North Pacific Ocean as well as the mathematical model ship, various kinds of stochastic routing simulations are carried out for Tokyo-San Francisco route. As a result of the simulations, it is concluded that the proposed method can provide the shipmaster/owner with sufficient information to determine the optimum route in the stochastic sense.
