This study uses exergy analysis to evaluate the fuel-saving potential of a waste heat recovery unit (WHRU) integrated with an Organic Rankine Cycle (ORC) system for marine applications. Data from the training ship HANBADA of the Korea Maritime University and the general cargo ship BBC CAMPANA, including their operational routes and main engine loads, were used in this study. Simulations indicated that the WHRU system could save approximately 27.5 metric tons of fuel per voyage, equivalent to approximately 2.1% of the total fuel consumption. The WHRU system demonstrated a higher efficiency during long-distance voyages, significantly enhancing fuel savings. In addition, higher engine loads increased the exhaust gas thermal energy, thereby substantially improving the WHRU output. This study emphasizes the importance of evaluating the applicability of the ORC system for marine vessels by closely examining their operational patterns, navigation duration, and main engine load variability.
