Abstract:
Rising of fuel price, global warming, and dependency on oil was encouraged researches
to find alternatives solution in order to minimize the dependency on the fuel. One of the
alternative solutions is by using wind turbine as a renewable energy. Wind turbine can
propel a boat at all directions to the wind including directly to windward. This thesis
presents a study the usage of wind turbine assisted propulsion system on boat as second
device. Savonius type of wind turbine was chosen as a second device for Discovery IX
which is one of FMSM research boat. This turbine was designed and the amount of power
saving was calculated base on previous study. Then, economic analysis was analyzed
based on the propulsion force of the turbine. By using this device, it shows that it can
save fuel consumption up to 40% in operation cost with selected route. The results of the
analysis indicate that Annual Average Cost (AAC) for boat with wind turbine is low than
the boat without wind turbine. Investment of the Savonius wind turbine on the Discovery
IX takes 1 year to recover.
