碩士 / 國立成功大學 / 交通管理科學系碩士在職專班 / 104 / In Today world, maritime transportation is increasing becoming an international mainstream business. Currently over 90% of global trade depends on maritime transport, but most of the merchant vessels use Heavy Fuel Oils (HFOs) for shipping propulsion, Subsequently causing a lot of environmental pollution. The contribution of ships to global emissions can be identify as follows in the following components: sulfur oxides(SOX), 12%；nitrogen oxides(NOX), 13%；carbon dioxide equivalent(CO2e), 2.8%. Liquefied natural gas (LNG), due to its environmental friendliness, safety and its fulfillment of the international emissions standards, has become the best choice for ships alternative fuel. The aim of this research is to analyze the five offshore ships that are currently operating in Taiwan and also to explore the environmental influences of using LNG alternative to traditional fuels by EPA and PLOA models, and further conduct a scenario analysis of SOX and NOX emissions of per ton-miles. The results show that LNG leads to a reduction of 90% of SOX emissions and 70% of NOX emissions and 10% of CO2 emissions in at least both modes. In the scenario analysis, the results show that in order to distinguish the type of route, then cross-strait routes should be a priority to promote LNG fuel and in order to distinguish the type of ship, then traditional vessels should be a priority to promote the LNG fuel.
Key words: Heavy Fuel Oils (HFOs), sulfur oxides (SOX), Liquefied natural gas (LNG), offshore ships, the cross-strait routes
