Abstract

Newcastle University's new research vessel, The Princess Royal, has been designed in-house by staff and students in the School of Marine Science and Technology. The new concept is a marriage of the catamaran and deep-V hull form concepts and provides the vessel with enhanced seakeeping, efficiency and speed. The data collected from wide range of sea trials has proven the superior hydrodynamic performance of the vessel as expected. However, some severe tasks during her research activities involving trawling and bollard pull tasks have caused propeller deformations and the efficiency of the propellers has been deteriorated. In addition the vessel was launched with a weight growth than the planned design displacement and hence the propellers of the vessel have been operating at off-design conditions. In order to address at the above problem a new set of propellers has been designed for the research vessel based on NPT (New Profile Technology) and the design is validated by the open water tests for the propeller efficiency and full-scale trials for the power-speed requirements, cavitation performance, hull pressures and underwater noise radiation (URN) This paper presents some details of the propeller design study, comparative model tests and full-scale trial results to validate the design study as well as to demonstrate the suitability of the NPT propellers for small size vessels, like The Princess Royal.
