Abstract
This paper evaluates the energy-saving potential of ships by analyzing their carbon dioxide emissions on 20 oceanic voyages using weather routing. The Energy Efficiency Existing Ship Index (EEXI) is used to measure a ship's energy efficiency. The voyages include routes connecting major international seaports and hubs in Asia and North America. Practical measurements were taken on board the ships using weather routing reports and ship record data. The study reveals that the E05 and W05 routes are the most energy-efficient, while the E01 and W08 routes have the highest emissions and fuel consumption. The E05 route has the optimum EEXI and the lowest CO2 emissions. Conversely, the E10 route has the highest EEXI, while W08 has the highest fuel consumption and the worst EEXI. The study emphasises the importance of reducing greenhouse gas emissions and improving energy efficiency in the shipping industry. The results demonstrate the potential benefits of using weather routing and EEXI for assessing and improving the energy efficiency of ships.
