The maneuvering motions are solved by differential equations of motion for every moment throughout the voyage. Moreover, the navigation route, expressed in terms of a B?zier curve, is optimized for minimum fuel consumption by the Powell method. Although the optimized route is longer than the great circle route, simulation results confirm a significant reduction in fuel consumption. This method is widely applicable to finding optimal navigation routes in other areas.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Route Planning, Route Optimization, Oceangoing Vessel, B├ęzier Curve, Powell Method, Great Circle Route, Fuel Consumption, Hydrometeorological Aspect} }
