Integrated power systems in small passenger ships

This paper deals with the application of integrated power systems in small passenger ships. Namely, integrated power systems were up to now mostly used in naval and large passenger ships, primarily for financial reasons. However, despite their complexity, such systems allow for much more versatility and their application in small passenger ships seems to be advisable in the context of environmental issues. Environmental aspects of maritime transportation are discussed, the needs for environmentally-friendly ships in the Adriatic Sea are elaborated and a review of actual IMO Regulations is provided, pointing out the effects of introducing new fuel-efficient and electrified ships. Different power systems of a ferry operating in the Adriatic Sea are analyzed in detail, with particular emphasis on gas emissions. Direct mechanical propulsion system and integrated power system in real operating conditions are considered and some advantages and drawbacks of both are examined. Finally, discussion of the results is presented and valuable conclusions are drawn. It should be mentioned that selection of proper power system, based on a holistic approach, can significantly reduce environmental pollution without affecting ship operational characteristics.
