Abstract: This final year report presents the two different ship cases to which are matched to four different ESS types. The rationale behind this is to enable easier comparisons of different kinds of ESS types against a case study of the two ships. This is to verify if the installation of the ESS on ships is beneficial against fuel consumptions at low lows. The report first starts off by defining the general requirements on board ships, and the conditions and parameters of the ESS. It goes on to explain the load profile of the ferry and coast guard vessel respectively, followed by the limitations faced by the author when approaching the case studies. Different kinds of energy storage types such as lithium ion batteries and lead acid batteries are also discussed. Information on super capacitors and fly wheels are included as there is a real possibility of them being able to be implemented onto ships as well. Secondly the ships electrical systems are described, based on Rolls Royce Marine Tool the safe line and save safe configurations are discussed. The issue of low load management will be approached and the effects like wet stacking will be mentioned. Solutions such as using a portable load, making use of spinning reserve and peak shaving are suggested. In conclusion the reports presents the sizing of the ESS based on the load profile of the ships and the four kinds of batteries. Calculations with regards on how the sizing is estimated, with limitations in variables and results will be shown. In addition the report will attempt to suggest the best possible fit of ESS with the ships. Finally, the report may serve as a guide for future reference on the control and integration of Energy Storage Systems for Electric and Hybrid Ships.
