heal.abstract Purpose of this thesis is to gather and keep a record of the technical characteristics of ferries covering small distances in Greek waters and these routes. As far as ferries are concerned their principal dimensions, service speeds, number of passengers and vehicles, power of main engines, generators and emergency generator are recorded. Concerning routes, distance, required cruising time, available time at port and frequency of routes are recorded. Afterwards, a classification is made according to distance and frequency of routes. Further analysis is provided with the use of Retrocalc, a computational tool that Mr. Michail made, for each route and ferry separately. Input data for each route is presented analytically as well as output data and thus with the run of the program effect of the different characteristics of ferries and routes (variants of the program) are interpreted. Comparisons between different routes and different scenarios of same routes are made, which also helps to interpret the effect of different variants (time at port, engine power etc.), leading to the selection of the desired characteristics of ferries to be electrified. Finally, the economic results are presented; taking into account all necessary technical details (e.g. required number of batteries) and the routes are classified according to their cost of retrofit-deadening. Except these, a historical review is made of electric ships in the past as well as future projects and tendencies are presented. Technology of batteries is analyzed, including mechanisms and chemistries of all categories of batteries that are used on board. The retrofit procedure is developed thoroughly along with the necessary rules, regulations and legislations that shall be followed. All possible vessel to shore connection systems and designs of electrical topologies on shore and on board are presented. An environmental study is carried out with the effects on human health, environment and economy mentioned. Regulations for the control of hazardous substances and possible ways to reduce emissions are presented as well as a targeted study for the production of electricity in Greece, to conclude that an all-electric ferry is an interesting and favorable choice from all perspectives (technical, economical and environmental) and shall be encouraged by Greek authorities. en
