Ship emissions reduction targets are forcing the maritime transportation industry on the way to replacing conventional marine fuel oil with cleaner fuels. This is especially significant for ocean-going vessels that carry huge cargo such as container ships. Therefore, the present paper aims to perform environmental and energy efficiency analysis for the utilization of liquefied natural gas (LNG) instead of conventional marine fuel to reduce the carbon-footprint and enhance the energy efficiency of container ships. In this study, the environmental analysis is based on the calculation of ship emissions released by using dual-fuel engine powered by LNG and compared with that released by conventional ones. The results show that the conversion process has achieved a 30% reduction in carbon dioxide, 81% reduction in nitrogen dioxide and 97% reduction in sulfur oxide. While the ship's energy efficiency is assessed by using the design index which shows that LNG can comply with the current rules and future ones.
