论文已在中国上海举行的第27届CIMAC大会上发表。论文的版权归CIMAC所有。In a ship, it is necessary to design in consideration for greenhouse gas reduction,(smoke, NOx) and fuel consumption reduction. In general, the propulsion system of tugboat is designed with rated horsepower for required bollard-pull. However, in gen-eral almost harbor tugboats are operated under the low load except the moment of ship berthing to fulfill the operation pattern. In order of the customer, it isnecessary to design a ship to operate in good conditions of the system performance. Therefore, we have developed hybrid system for tugboat applying electric motor and battery similar to a Hybrid-Vehicle. The propulsion system power source of this system consists of diesel engine and electric motor powered by electric current from high density battery. Installation area becomes smaller in comparison with a lead battery. By adopting the high density battery that is effective for the ships which installation space is relatively limited to vessels such as tugboats. This hybrid system could reduce 20% fuel consumption and a green-house gas in comparison with the conventional system. First hybrid tugboat in Japan will enter in service early 2013. If the new development called the hybrid propulsion system ship can be established, thissystem will be in contribution to the shipping industry. This paper explains the introduction, development summary and effect of the hybrid system.
