| Summary | Today, maritime transport has become an international mainstream. 90% of global trade depends on maritime transport, but most of the merchant vessels use Heavy Fuel Oils(HFOs) for ship propulsion, causing heavy environmental pollution.The contribution of ships to global emissions can be indicated as being in the following:sulfur oxides(SOX), 12%；nitrogen oxides(NOX), 13%；carbon dioxide equivalent(CO2e), 2.8%. Liquefied natural gas (LNG), due to environmental friendly, safely and meet international emissions standards , has become the best choice for ship alternative fuel. The aim of the research presented in this paper is to analyse five offshore ships which operating in Taiwan, and to explore the environmental influences of using LNG alternative to traditional fuels by EPA and PLOA models, and further to carry on scenario analysis of SOX and NOX emissions of per ton-miles. Results show that LNG leads to a reduction of 90% SOX emissions and 70% NOX emissions and 10%CO2 emissionsin at least both modes. In scenario analysis, results show that in order to distinguish the type of route, the cross-strait routes should be a priority to promote LNG fuel; in order to distinguish the type of ship, traditional vessels should be a priority to promote the LNG fuel. |
