碩士 / 國立高雄第一科技大學 / 環境與安全衛生工程研究所 / 103 / The worldwide fuel consumption of ships has reached 500 million tones per year, according to statistics. Global warming has become more serious due to about the emission of 1.6 billion tons of CO2 and 30 million tones of SO2. In Taiwan, there are more than 180 ships are under the jurisdiction of Coast Guard Administration and the annual fuel consumption is close 18,000 tons. Consequently, Coast Guard Administration are considered to conduct a issue on carbon reducing in ships in speed-down state from the view point of green shipping. In this study, the actual operation data for the tonnage of more than 500 tons were measured and analyzed including the fuel consumption of ship hosts and generators in different speeds, distances and tonnes. Carbon emissions from greenhouse gases of moving sources were calculated by using the recommended equation of World Business Council for Sustainable Development (WBCSD). The study has been carried out the approximate calculation of carbon emissions from ships according to the actual fuel consumption. The exclusion of a number of factors such as weather, wind and ocean currents, etc., the carbon emission in the host per ship is significantly reduced by nearly 42% in low speed process and the fuel consumption is reduced on average by 54% than the most high-speed process. Without taking into account the time factor, simulation results in different shipping lines and 20% speed down show that carbon emissions are reduced by 28 percent on average. Fuel consumption is reduced by an average of 42%. According to statistics, carbon emissions of the host each ship is relatively low in low ship speed.
