摘要：During ship design,its service speed is one of the crucial parameters which decide on future economic effects.As sufficiently exact calculation methods applicable to preliminary design stage are lacking the so called contract speed which a ship reaches in calm water is usually applied.In the paper [11] a parametric method for calculation of total ship resistance in actual weather conditions (wind,waves,sea current),was presented.This paper presents a parametric model of ship propulsion system (screw propeller - propulsion engine) as well as a calculation method,based on both models,of mean statistical value of ship service speed in seasonal weather conditions occurring on shipping lines.The method makes use of only basic design parameters and may be applied in preliminary design stage.
