AN EXAMINATION OF THE PROPOSED ENERGY MANAGEMENT SYSTEM MODEL FOR SHIP AND PORT INTERACTION

In this study, ship energy management model has been developed to be applied to next-generation ships and port concepts and to supply electrical energy demand of ships from alternative energy sources. With this model, when at ports, ships can use both their generators and national electricity grid considering financial and environmental criteria. Thus, ship crew will be able to select the cleanest energy source to meet the likely requirements arised from any environmental restriction based on international contracts. Ship crew will also be able to select the most economic energy sources, if any environmental criteria has been set at the port. In this study, MATLAB software has been used in ship energy management model and the relevant simulations. In the simulations, the data of “M/V Ince Hamburg” bulk carrier ship and national electricity grid of Turkey have been taken into account to obtain acceptable results. The two types of ships using only own generators and having energy management system and shore-side connection have been compared. The results show that the proposed ship energy management model will save about 46% reduction in energy costs and a reduction of about 33% in CO2 emissions
