经济性：内河船＂油改气＂的关键推动力

Cost-effectiveness： Key drive of inland ship ＂oil-to-gas＂

一年以来，国际原油价格经过大幅下跌后维持低位振荡之势，使LNG（液化天然气）燃料的经济性受到极大影响。作为水运行业推进节能减排和生态文明建设的重要抓手．LNG动力船舶的推广一度遭受严重打击，因而暂时放缓了脚步。

International crude price has remained in low level for one year after plummets, substantially eroding the LNG fuel cost-effectiveness. As an important drive for promoting energy conservation and emission reduction and ecological civilization construction, LNG-powered ship popularization was stricken as a serious blow, thus temporarily slowing down.
