Abstract

The increasingly stringent international environmental protection requirements and the progressively tougher compliance requirements of shipowners have also put forward new development needs for low-emission, clean-energy vessels. At present, more than 90% of China's water transport ships still use diesel-powered propulsion systems, which have issues such as high fuel costs, high noise levels, and pollution emissions. Compared with traditional ship power systems, the ecological advantages and comprehensive benefits of electric propulsion-type ships are obvious. However, there are also issues, such as shorter range and battery life, which need to be analyzed in depth. This paper establishes a life cycle energy consumption model and emission model for the comprehensive benefits of electric ships and conducts an economic benefit analysis. The results show that electric ships have significant advantages in environmental protection, energy saving and lower costs while electric ships for containers have great prospects for future development. This paper provides a useful exploration for the international shipping industry to adopt effective measures to control ship emissions.

电动集装箱船能耗与排放分析

国际环保要求日益严格，船东的合规要求也日益严格，对低排放、清洁能源的船舶提出了新的发展需求。目前，中国90%以上的水运船舶仍然使用柴油动力推进系统，存在燃料成本高、噪音水平高和污染排放等问题。与传统船舶动力系统相比，电推进型船舶的生态优势和综合效益明显。但也存在续航里程短、电池寿命短等问题，需要深入分析。建立了电动船舶全生命周期综合效益的能耗模型和排放模型，并进行了经济效益分析。结果表明，电动船舶在环保、节能、低成本等方面具有显著优势，集装箱电动船舶未来发展前景广阔。本文为国际航运业采取有效措施控制船舶排放提供了有益的探索。

期刊介绍： Ocean & Coastal Management is the leading international journal dedicated to the study of all aspects of ocean and coastal management from the global to local levels. We publish rigorously peer-reviewed manuscripts from all disciplines, and inter-/trans-disciplinary and co-designed research, but all submissions must make clear the relevance to management and/or governance issues relevant to the sustainable development and conservation of oceans and coasts. Comparative studies (from sub-national to trans-national cases, and other management / policy arenas) are encouraged, as are studies that critically assess current management practices and governance approaches. Submissions involving robust analysis, development of theory, and improvement of management practice are especially welcome.
