Tiivistelmä
This master’s thesis focuses on studying the applications of the permanent magnet shaft generator in the marine industry. The work has two objectives. First is to assess the number of applications of direct drive permanent magnet shaft generators in marine applications today and in the future. The second is to determine how the applications of diesel mechanical propulsion systems and diesel electric propulsion systems differ in the marine industry.
The analysis of the number of applications started by finding suitable ship types based on previous references of the commissioner, technological requirements, and a literature review. A 1MW or more auxiliary power limitation was used as a primary selecting criteria for the ship types included into the analysis. EEDI auxiliary power calculation equations were used to investigate the impact of 1 MW or more auxiliary power limitation on the total propulsion power. The effect of total propulsion power on ship size was evaluated in terms of IHS database. The number of ships for the selected ship types and sizes were collected from the 2022 World Merchant fleet statistics from equasis report.
Based on the results, the suitable ship variations are very large gas tankers, large and very large container ships. The percentage of applications according to the 2022 merchant ship statistics is 3,1%. Lowering the auxiliary power limitation from 1MW to 0,75MW would increase the percentage of applications to 7,1%. No potential applications for a diesel-electric propulsion system were found from the selected suitable ships due to their size and their purpose in the marine industry.
