Optimization of Propeller Performance Characteristics

Abstract

This paper presents the computational tool designed to calculate and optimize the performance characteristics of marine propellers, specifically Wageningen B-series propellers. The tool consists of two main modules: the thrust calculator, which estimates the thrust and efficiency of a propeller based on empirical and experimental data, and the optimization module, which utilizes brute-force and genetic algorithm methods to determine the optimal propeller configurations. By integrating basic input parameters such as ship speed, propeller diameter, pitch, and other essential characteristics, the tool is implemented to search for and find the solution for improving propulsion efficiency. The effectiveness of the tool is demonstrated through case studies on two vessels, a container ship and a special-purpose vessel, where significant improvements in propeller performance were identified. The tool as described in this paper represents a straight forward method for propulsion performance optimization in practical maritime operations.
