HIGHLY SKEWED PROPELLERS--FULL SCALE VIBRATION TEST RESULTS AND ECONOMIC CONSIDERATIONS

This paper presents full-scale test results and discusses the effectiveness of three different highly skewed propeller designs in reducing ship vibration. The test results cover three merchant ship designs, including one OBO vessel and two RO/RO vessels, having installed horsepower ranging from 24,000 to 37,000 SHP. Limited discussion is presented on the relative effectiveness of installing a highly skewed propeller versus adding additional structural reinforcement on a vessel to reduce excessive vibration. Some economic factors that should be considered by a ship owner contemplating a highly skewed propeller for a new ship design are presented.
