Today, approximately 85% of world trade is carried out by sea and ships are indispensable elements of transportation, logistics and trade. But on the other hand, approximately 2.5% of global green gas emissions, which have adverse effects on air quality and public health, is originated from ships and maritime transportation activities. Considering this situation, the International Maritime Organization promotes the use of renewable/alternative energy sources on ships, rather than fossil fuels. In the 11st Development Plan of Republic of Turkey, it is also aimed to convert the ships used for vehicle and passenger transportation in a short distance into “all-electric” concept. In this study, energy system analysis and modelling of a new generation ferry with a diesel electric propulsion system, which is used for vehicle and passenger transportation, have been carried out by using the Reference Energy System approach and Long- range Energy Alternatives Planning System software. In conclusion of the study, results of analysis related to the ferry’s energy system, which also include theoretical emission estimates for conversion scenario of the ferry’s energy system into hybrid concept, have been presented. Additionally, some suggestions for increasing energy efficiency of the ferry have been presented as well.
