Summary

In this thesis, the optimization of a conventional ship with a cogenerationunit in terms of engine operation during the voyage is firstly studied. The"weaknesses" of the conventional propulsion system are identified and a newsystem with electric-propulsion, i.e. the propeller is rotated by electric mo-tors, is counter-proposed. In addition, an energy storage unit with batteriesand an electricity production unit using photovoltaics are introduced intothe system. Finally, various travel scenarios are studied and a comparisonis made between the conventional and the electric powered ship, but alsobetween the practices used in these scenarios.
