Research Summary: Marine shipping industry contributes the carriage of 90% of world trade which also causes the problems of ship emission and fuel inefficiency. Conventionally, the tugboats are propelled by diesel mechanical propulsion whereby the engines are sized to maximum working propulsion but operating merely at about 20% of total operational time. Hence, the hybrid solution is widely regarded as a more cost saving alternative to reduce emission and fuel consumption.
This research work mainly focuses on the comparative performance analysis of the use hybrid propulsion with respect to the conventional diesel engine propelled vessel in term of fuel efficiency and return of investment (ROI). The work will start from the study of operational profile of the target vessel, i.e. tugboat, operational along the Rejang River. Specific measuring method will be proposed to obtain technical data of vessel in operation for both cases (1) diesel engine only (2) hybrid system and batteries.
