Abstract

Abstract For the maritime sector to be sustainable and to have an intact blue economy, shipowners should be ready to implement Ship Energy Efficiency Management Plans alongside energy efficiency projects. The problem for organizations and shipowners having fishing carriers older than 20 years is highlighted and the following challenges arise for decision-making authorities. To keep such ships in the fleet for the next decade, shipowners should deploy energy efficiency projects for marine system retrofitting to improve energy efficiency and meet environmental regulations. An energy audit is performed and an energy efficiency program is proposed with guidelines for regulations that are currently coming into force. To improve energy efficiency, reduce the environmental impact, and cut fuel consumption costs, marine system retrofitting is done, in a particular case, with two options proposed. The first is a cascade refrigeration system with hydrocarbons and carbon dioxide, where the shipowner gains an energy efficiency improvement of about 20%. The second option is a two-stage refrigeration system with ammonium as the environmentally friendly refrigerant, which improves the energy efficiency by about 26%. Technical and economic issues have been discussed.

未来可持续的海事部门：提高20年以上渔船的能效和减少环境影响第二部分

摘要为了使海事部门可持续发展并拥有完整的蓝色经济，船东应准备好在实施能效项目的同时实施船舶能效管理计划。强调了拥有20年以上捕鱼船的组织和船东面临的问题，决策当局面临以下挑战。为了在未来十年内使此类船舶保持在船队中，船东应部署用于海洋系统改造的能源效率项目，以提高能源效率并满足环境法规。进行能源审计，并提出能源效率计划，以及目前生效的法规指南。为了提高能源效率、减少环境影响和降低燃料消耗成本，在特定情况下，对船舶系统进行了改造，并提出了两种选择。第一种是含有碳氢化合物和二氧化碳的级联制冷系统，船东的能效提高了约20%。第二种选择是使用铵作为环保制冷剂的两级制冷系统，这将能源效率提高约26%。已经讨论了技术和经济问题。
