Abstract:The shipping industry is facing increasing requirements to decrease its environmental footprints. This challenge is being addressed through the use of alternative fuels and adoption of novel energy sources in advanced power and propulsion systems. In this paper, an energy management approach is proposed for determining the optimal split between different energy sources of a vessel with hybrid power generation. The power and propulsion system of the vessel consists of a gas engine and a solid oxide fuel cell, both fed with liquefied natural gas, and a battery. Specific fuel consumption curves and transient capabilities of the engine and fuel cell are used to determine the optimal split and the battery is used for responding to the major and fast load transients during heavy operations and also providing power during low power demanding activities. The performance of the proposed approach is evaluated for a dredging vessel with a DC power and propulsion system. The results indicate an increase in fuel efficiency of 21% compared to conventional non-hybrid power generation using the conventional approaches.
