液化天然气渔船改造相关技术分析

摘要

为降低渔船燃油能耗，减少渔船污染排放，研究了液化天然气渔船（ LNG渔船）相关技术。 LNG渔船的核心技术在于双燃料发动机动力装置，围绕双燃料发动机动力装置所需空间的利用和布置是LNG渔船改造的一大难点。双燃料发动机动力装置相关配套设备科学合理的设计也是保证LNG渔船高效航行的重要因素。通过对LNG渔船船体改造、双燃料发动机动力装置改造和LNG燃料存储技术等方面进行分析，认为LNG渔船作为一种新型船舶，能有效地降低渔民燃料成本，改善船员作生活环境。%According to the spirit of our country’ s sustainable development strategy, in order to cut down the fuel consumption of fishing vessels, and to reduce fishing vessels’ pollution, trelevant technologies of LNG fishing vessel. Compared with traditional fishing vessel, there is a lot of innovation and breakthrough in technology for LNG fishing vessels. The core technology of LNG fishing vessel is dual fuel engine power plant. The use and arrangement of the space around dual fuel engine power plant is a big difficulty. The scientific and rational design of power plant’ s corollary equipment is an important factor for LNG fishing vessel’ s efficient navigation. Through analysis on LNG fishing vessel hull transformation, dual⁃fuel engine power plants renovation and LNG fuel storage technology, LNG fishing vessels, as the new type of fishing vessel can reduce fisherman’ s fuel cost and improve crew ’ s living environment. LNG fishing vessels conform to China ’ s sustainable development strategy, and it should be developed actively.
