挖泥船LNG燃料系统设计及安装工艺研究

Design and Installation Process Research of Dredger LNG Fuel System

船用LNG燃料现已作为国际公认的“环境友好”型能源,被航运市场逐渐运营使用,但目前还处于初期应用阶段。本文通过阐述LNG燃料系统的工作原理和设备构成,结合公司实际研究项目15000 m3耙吸式挖泥船低压LNG双燃料系统的实船建造经验,阐述低压LNG双燃料系统设备设计及安装要点,可为承接相关的LNG燃料船提供技术储备。

Marine LNG fuel is now internationally recognized as environmentally friendly energy,and being used gradually for operation in the shipping market,but still at the initial usage stage at present.This article expounds in detail the working principle and equipment composition of LNG fuel system,and elaborates the design&installation key points of low pressure LNG dual fuel system equipment in combination with construction experience accumulated in the low-pressure LNG dual fuel system of 15000 m3 trailing suction dredger e.g.our company actual research project,which would provide technology reserve support for the future relative LNG fuel ships to be undertaken by our company.
