| Résumé | This research aims to systematically evaluate the impacts of hull forms, propellers, rudders, and other appendages on domestic vessels' hydrodynamic and URN performance. The study also seeks to improve understanding of the hydrodynamic interactions between the hull, propeller, rudder and appendages and the resulting impacts on performance efficiencies, GHG and URN emissions of Canadian domestic boats. As a crucial first step, the research team selected and physically modelled two representative Atlantic Canadian fishing vessels at suitable scales. The team utilized comprehensive suites of physical modelling facilities and techniques to conduct the investigations on the hydrodynamic performance evaluations of the fishing vessels at realistic operating conditions in terms of bare and appended hull resistance, powering predictions using self-propulsion tests, free running maneuvering and seakeeping performance. This paper presents selected outcomes of the measurements we acquired through the physical modelling campaign on the powering and manoeuvring performance variations due to changes in commonly used hull appendages and propeller-rudder configurations. The hull appendages and rudder types are found to have significant impact on the overall powering and maneuvering performance of the fishing vessel. This work is expected to generate knowledge and improve understanding to investigate the interactions of the vessel, propeller, rudder, and other appendages regarding hydrodynamic performance. The study will also provide support and solutions for the communities regarding the (optimized) design and construction of domestic vessels and provide insights into how professional and technical improvements can benefit vessel operations. |
