ABSTRACT:






































This design proposes an energy efficient solution aiming at the reduction of emissions generated by the fleet of one of the largest sections of international shipping, containerships. By designing a containerised battery system capable of providing 10.3MWh of useful energy, the ultimate aim is to replace an existing diesel generator onboard a containership and to operate the battery system on manoeuvring. Using a load planner software, it was ensured that such a system can be loaded onboard a specific containership, without negatively affecting the stability and the structural integrity of the vessel. The battery system can be charged both by a shore supply as well as during the seagoing part of the voyage, by using excess power produced by operating the running generators at their optimum point. The energy feasibility of such a system and the emissions reduction were verified by developing several software models, allowing various case study trips to be investigated. Results suggested that with such a system onboard, emissions can be reduced by 18.55% when the ship carries only normal containers and by 43% when the ship carries normal and refrigerated containers, showing that battery systems onboard can be proven beneficial on reducing emissions. However, the financial analysis performed indicated that such an investment would result to a loss, primarily due to the current price of battery systems. In the future though, the price of battery systems is expected to decrease, making such a system economically viable.
