基于船舶推动能耗的船舶运输效率发展趋势的定量分析(英文)

Quantitative analysis for the development of transport efficiency based on energy used for propulsion

船舶营运需要消耗大量的能源,而能源消耗不仅增加了企业的成本支出,而且会增加对环境的污染.船舶营运效率的提高会节约能源,大大降低成本和缓解环境污染,而船舶营运效率的提高涉及船舶能耗、航速、主机功率等诸多方面.分析劳氏从1970年至2005年三十多年间三种商用船型的统计数据,运用定量分析的方法来阐述船舶运输效率的发展趋势.

The operation of shipping industry consumes a large quantity of energy,while the energy consumption increases the costs and expenditures of shipping companies especially when the oil price is high,meanwhile,the energy consumption also results in environmental pollution.The improvement of transport efficiency will not only reduce the costs and expenditures,but also can be indispensable to mitigate the environmental pollution. However,the improvement of transport efficiency involves numerous aspects,including energy consumption,ship speed and power output and so on.This paper focus on the analysis of the Lloyd's statistical data of three types of merchant vessels during the more than 30 years from 1970 to 2005 through quantitative analysis method,to illustrate the development trend of ships's transport efficiency.
