SAILING SHIP WEATHER ROUTING

The purpose of this paper is to examine the effects of weather routing using monthly climatological data. The ship used in the simulation is the 17,000 dwt Dynaship. Two-way passages were simulated between New York and the English Channel during the months of January, April, July and October (as representative of the four seasons). A grid covering much of the North Atlantic was created and links between these nodes were selected to allow for a vast number of feasible routes. Winds were specified probabilistically from the pilot charts and a dynamic program was solved by computer to determine an optimal route based on given criteria. A series of passages for each of the above months was sailed as a Monte Carlo simulation where the winds were given by random deviates of the same probability distribution as the pilot charts. Optimum routes were compared with minimum distance routes (great circle shipping lanes) and found to be far superior. The effect of increasing the minimum vessel speed by auxiliary power on average vessel speed, fuel consumption and standard deviation of passage time was examined.
