There has been considerable interest recently in the topic of energy saving. This is Primarily due to highly risen oil price. The fuel charge is also getting higher in navigation cost. Therefore, ship owners try to reduce oil consumption. ESS(Energy saving System) is one of the method to reduce fuel consumption of ship. ESS is the System consisted with control unit, monitoring device and inverters. ESS control unit finds optimized point to decrease a power consumption of cooling sea water pumps. And inverter controls RPM of main cooling sea water pumps. ESS was installed on training ship HANBADA for performance and stability test. Test navigation was conducted and the results show that mean energy saving rate of coastal & ocean navigation was more than 40%.
