Master thesis projects on wind propulsion

Currently, much research is focused on the possibility to use wind propulsion to reduce the green-house gas emissions from shipping. Two master thesis projects in this field are jointly supervised by both Chalmers University of Technology and SSPA. “Investigation on a harvesting propeller for wind propelled vessels” and “CFD investigation of wind powered ships under extreme condition”. 

Investigation on a harvesting propeller for wind propelled vessels

In an ongoing research project, Wallenius Marine in cooperation with SSPA, KTH and Chalmers, a wind powered car carrier concept is being developed. This thesis project will complement this project by studying the propeller of wind driven ships and the possibility to use the propeller to generate energy when the wind conditions are favorable. That means when the wind drives the ship at such a large speed that the water rotates the propeller and energy can be generated at the shaft. This energy can be stored onboard and used for propulsion when the wind is less favorable.

CFD investigation of wind powered ships under extreme condition

Wind powered ships could be a feasible way to reduce the fossil fuel emission from shipping. In an ongoing research project, Wallenius Marine in cooperation with SSPA, KTH and Chalmers, a wind powered car carrier concept is being developed. The sails of this concept are planned to be very large rigid wings. Under normal operation, the flow over the wings will be attached. In some extreme situations, however, the wings may have such large angle of attack that the flow is partly or completely de-attached (stalled). A situation like that can potentially lead to large unsteady forces which may be harmful to the ship in terms of structural integrity and risk of capsizing.

The projects are jointly supervised by both Chalmers and SSPA. The supervisory team composed of Full Professor Rickard Bensow (supervisor, Department of Mechanics and Maritime Sciences, Division of Marine Technology, Chalmers University of Technology) and Dr. Sofia Werner (supervisor from SSPA). 

Application deadline for this thesis project is November 20, 2020. To submit thesis project, please visit Chalmers.se for more information.
