This work investigates the potential of three different energy efficiency technologies on a Very Large Crude Carrier: Organic Rankine Cycle and adsorption chiller for waste heat recovery as well as photovoltaics for the integration of Renewable Energy Sources. The analysis uses operational data acquired from an energy management system. It shows that the impact of the weight of each technology is negligible when compared to fuel savings and emission reductions. Based on the sailing conditions identified from the operational data, the study presents an estimation of the theoretical and technical potential showing the overall savings, which can be achieved on an absolute scale. Moreover, the achievable improvement of EEOI and CII are presented. The available waste heat and the electricity demand of the vessel are identified as the limiting factors for the technology implementation.     «
