New propeller design


Customer: Tevo Oy


To develop a marine propeller product family for ice class applications and to increase the design capability of the company.


For Tevo Oy, VTT has developed new features in propeller design software, and together with the client we have built the capability to design and optimize bronze propellers for ice class applications.


We reviewed and upgraded the propeller design process for regular open water and ice classed operations. The open water hydrodynamic design process review resulted in developing features for Tevo Oy’s propeller design software. This gives Tevo propellers improved efficiency. The material strength that Tevo uses was statistically analysed and was found to be actually stronger than the requirements of ship classification. This strength benefit can be used in optimizing propeller efficiency.
