DUCTED VERSUS CONVENTIONAL PROPELLERS: A COMPARISON BASED ON ECONOMY
This paper discusses the general economies of considering ducted propellers in comparison with conventional propellers and presents two approaches. Three examples are cited: the first for a 26,000 tonne dwt bulk carrier, the second for a 215,000 tonne dwt tanker and thirdly for a 65,000 tonne dwt OBO vessel. A computer programme has been developed which studies certain parameters, the variations of which are discussed.
