本研究的目的是就航运的技术和运营能源效率这一主题产生新的知识和见解，既帮助航运业利益攸关方了解其运营市场中能源效率的统计数据和驱动因素，又有助于围绕能源效率和温室气体减排的政策领域正在进行的讨论。这项研究是第一次使用卫星自动识别系统数据分析全球船队的能源效率，也是为了评价这一新的数据来源，并讨论其用于能源效率估计的好处和任何缺点。本研究在2011年对船队进行了研究，特别关注最近的慢蒸现象对不同船队（船舶类型和大小）的操作行为的影响程度，以及对能源效率的可能后果。除了描述不同船队的技术和运营效率外，还进行了分析，以评估能源效率是否体现在不同市场的价格（定期租船、新造、二手）和选择船舶拆解方面。
The objective of this study is to generate new knowledge and insight on the subject of shipping‘s technical and operational energy efficiency, both to assist shipping industry stakeholders in understanding the statistics and drivers of energy efficiency in the markets in which they are operating, and to contribute to the ongoing discussions in the policy sphere around energy efficiency and GHG emission reduction. This study, which is the first to use Satellite Automatic Identification System data to analyse the energy efficiency of the global fleet, is also intended to act as an evaluation of this new data source and a discussion of its benefits and any shortcomings when used for the estimation of energy efficiency. Studying the fleet in 2011, this study‘s particular focus is on the extent to which the recent phenomenon of slow steaming‘ has influenced operational behaviour in different fleets (ship types and sizes), and the probable consequences to energy efficiency. As well as describing the technical and operational efficiency of different fleets of ships, analysis is also undertaken to assess whether energy efficiency appears to be represented in prices (time charter, newbuild, second-hand) in different markets and in the selection of ships for scrapping.
