Waste heat recovery systems for power generation are gaining interest among the marine transport sector as asolution to accomplish the upcoming more restrictive regulations on emissions and to reduce the total fuelconsumption. In this paper we evaluate how a waste heat recovery system based on a regenerative organic Rankinecycle (rORC) could improve the performance of a passenger vessel. The case study is based on the M/S BirkaStockholm cruise ship, which covers a daily route between Stockholm (Sweden) and Mariehamn (Finland).Experimental data on exhaust gas temperatures, fuel consumption and electricity demand on board were logged for aperiod of four weeks. Based on the optimal fluid and configuration obtained in a previous work, an off-design modelof a rORC working with benzene was used to estimate the power production at the different load conditions during aport-to-port trip of the vessel. The power generation curve of the rORC over time was compared to that of theelectricity demand of the ship. Results showed that the rORC could provide up to 16% of the total power demand.However, this value should be corrected if the auxiliary engines load is reduced as a consequence of the partialcoverage of the electricity demand by the ORC.
