Application of savonius turbine behind the propeller as energy source of fishing vessel in indonesia

Abstract

Abstract The energy wasted by the propeller of vessel can be gained as benefit by converting it using turbine as the source of electrical energy. The electrical energy can be used as the main energy source of fisherman vessel. The method in this research is redesigning the fisherman vessel combined with savonius turbine to obtain the correct dimension. Vessel dimension is built within Loa = 30.71 m; B = 7.67 m; H = 3.5 m; T = 2.2 m. From those dimensions can be obtained the coefficient between the propeller into the pitch 0.8 m, with the turbine diameter 0.5 m and the position of the turbine 0.1 m from the propeller. Savonius turbine captures electrical energy that produced by the low fluid flow that comes out from the propeller rotation, and will be converted by the generator inside the turbine to become energy. The power produced by the rotation of 1.31 rpm of the turbine is 25.689 kilowatt. It is enough to supply the engine generator with the power of 20.1 kilowatt from the power that produced by the turbine as big as 25.689 kilowatt to lighting the fisherman vessel. This technology can be applied massively to the fishermen vessel as renewable energy.
