| Abstract:The classification standard of underwater-radiated noise of ocean research vessel is introduced, Based on the study of typical main propulsion shafting and propeller system of research vessel with DNV·GL SILENT-R notation, the noise sources from main propulsion shafting and propeller system are analyzed profoundly. Based on theoretical study and experiences, the design and type selection method of main propulsion shafting and propeller system to reduce underwater noise is putforward, which has been applied on a research vessel and approved by DNV·GL experts. |
| Key words: research vessel main propulsion shafting and propeller system underwater-radiated noise low noise |
