Abstract: As a clean energy, liquefied natural gas (LNG) can effectively reduce the emission of nitrogen oxides, carbon dioxide and sulphide as well as micro particles. However, LNG fuel has not been fully popularized for inland vessels due to various factors. The influence of these factors should be considered for LNG powered oil tankers in the inland transportation. It introduces the application of LNG for inland vessels, and researches and analyzes the three problems of LNG as marine power fuel in the main engine selection, the LNG fuel supply and the safety of LNG transportation. The relevant technologies, resources and regulations are sorted out through the investigation and analysis to prove the feasibility of the application of LNG fuel on the inland oil tankers.

Key words: inland tanker, liquefied natural gas (LNG), dual fuel, main engine selection, refueling

摘要： LNG作为一种清洁能源,可有效减少氮氧化物和二氧化碳以及硫化物和微小颗粒等的排放。不过,由于各种因素,LNG燃料在内河船还未得到普及,LNG燃料动力油轮在内河运输更是需要考虑各种因素的影响。文章介绍了内河船舶LNG应用现状,针对面临的“LNG作为船舶动力燃料在主机选型、LNG燃料补给、LNG运输作业安全”这三个问题进行研究和分析。通过调查、分析,对相关技术、资源和政策进行梳理,从而得出内河油轮应用LNG燃料的可行性。
