USE OF LONG-RANGE WEATHER FORECASTS IN SHIP ROUTING.
Abstract
The report presents an operational computer program for the calculus of variations method of minimal-time routing of single ships. Although written specifically for VC2AP3 and VC2AP2 vessels operating in a described area of the north Pacific Ocean, the program can be modified easily to provide routes for other type vessels in any ocean area of the northern hemisphere. An improved method is used for varying time-extremal ship tracks toward admissibility, which requires only 30 seconds per track iteration, and which gives the desired route in about 3 minutes without convergence difficulties. The method of incorporating weather forecasts into the preparation of minimal-time ship routes is described, and possible future developments are discussed. (Author)
