摘　　要：传统柴油机的排放已难以满足日益严格的公约要求,使用清洁燃料的LNG动力船已成为主流趋势。LNG燃料具有储量大、经济性好、排放污染小等特点,但由于其本身物理特性及船舶设计,LNG动力船也存在着一定的危险。针对天然气漏泄引起的爆炸和着火,文章介绍了LNG动力船舶的通风设计和可燃性气体的检测,通过加强通风、安装气体探测器、使用全熔透对焊接头管路等措施[1]有效防止天然气漏泄,提高船舶安全系数。It is difficult for stringent conventions. LNG traditional diesel engine powered ship becomes a emission to meet the requirements mainstream trend As clean fuel, of increasingly LNG has large reserves, good economy, low emission pollution, etc, but because of its physical properties and ship design, LNG powered ship also exists certain risk. Aimed at explosion and fire caused by gas leakage, this article introduces the LNG powered ship ventilation design and inflammable gas detection, by strengthening ventilation, installing gas detectors, using full penetration butt joint measures pipes effectively prevent gas leakage, improve the safety factor of the ship.
