Abstract
A method for selection of parameters of ship propulsion system fitted with compromise screw propeller This paper concerns an algorithmic method for preliminary selection of parameters of ship propulsion system fitted with fixed screw propeller in the case when the ship's operation is associated with significant changes of waterway depth and width, hull resistance of the ship and its service speed. Mathematical model arguments of the considered design problem are main ship design parameters identified in the preliminary design stage. Structure of the formulated model complies with formal requirements for continuous- discrete mathematical optimization problems. The presented examples of application of the method concern an inland waterways ship fitted with compromise screw propeller optimized in the sense of minimization of fuel consumption for passing a given route distance within a given time. The elaborated method may be especially useful in designing such ships as: coasters, inland waterways ships, tugs, pushers, trawlers, mine sweepers, icebreakers etc.

AND PROBLEM DESCRIPTIONA method for selection of rational, or optimum in a given sense, technical solutions of a ship should take into account, already in the preliminary design stage, both obligatory and crucial design conditions and constraints
This paper concerns a method for determining, in the preliminary design stage, optimum values of the parameters of ship propulsion system fitted with fixed screw propeller in the case where hull resistance and service speed of the ship significantly varies during operation, that often takes place in the case of inland navigation
The voyage duration time, τz, determined by the design assumptions is connected with the speeds νi for covering distance of particular route sections, by the following relation :
