Use of Ship Main Engine Cooling Water for the Design of Micro Hydro Power Plants

The present study highlights the use of Ship Main Engine Cooling Water for the Design of Micro Hydro Power Plants. Renewable energy is non-fossil energy that is derived from nature and is sustainable. If resources are managed effectively, they can also run out. By using the cooling water flow pressure machine ships as a water turbine impeller manufactured in such a way so it may create electricity, he uses the cooling water disposal on his boat as an environmentally friendly energy-producing method. Commercial ships typically use large-capacity cooling systems and large-sized machinery, therefore the cooling water flow capacity will be considerably higher. This prompted the opportunity to create an instrument for utilizing renewable energy flow of cooling water disposed in vain to rotate the propeller has been drafted into a micro hydro. And expected results can help reduce the workload of the auxiliary engines which will also have an impact on the reduction of fuel consumption. The proposed water turbine will rotate as a result of fluid flowing by the pump, producing electrical energy. When the ship sail, the lighting definitely need in each room, by using the electrical energy produced by the auxiliary engine, this water turbine can be applied then the fuel that had been used or consumed by the auxiliary engine can be replaced by the electric energy generated by the water turbines for light ships. Testing of the prototype for a micro hydro generator aboard a ship yielded a 40% efficiency. Thus, it can be said that this ship's micro hydro power system can reduce energy consumption by up to 40%.
