TIMED ARRIVAL OF SHIPS AT PORTS

Ships currently often spend long periods at ports waiting for berths; considerable savings in fuel costs could be achieved by speed reductions during the voyage calculated to time the arrival of the ship as a berth becomes vacant. Currently this is not feasible as ports commonly allocate berths in order of arrival, but with modern communication and port management techniques this practice must be regarded as outmoded, since it is possible to predict berth occupancy for some weeks ahead and to inform ships accordingly of the times at which the berths to which they have been allocated will become vacant. The authors first show how the savings in fuel consumption resulting from reductions in speed are calculated, and then describe an algorithm for a computer program that enables the speed required for the ship to arrive at the required time to be determined; this would need to be run at regular intervals to take account of unforeseen changes in port conditions, weather conditions that affect the speed the ship can maintain, etc.
