LNGCME-GI低速机与TFDE电力推进对比

摘要

In order to satisfy the economy and environmental protection requirements of the ship , large LNG carrier propul-sion system was improved .In view of the target ship , from a technical point the two latest propulsion ways of the ME-GI low-speed engine propulsion and TFDE electric propulsion were analyzed emphatically .The analytical results showed that the ME-GI low-speed engine to promote both economic and environmental protection systems are better than the current mainstream TFDE e -lectric propulsion system , it will gradually become the mainstream of future large LNG carrier form .%针对满足船舶的经济性和环保性要求，大型LNG运输船推进系统更新换代的问题，从技术角度着重对比目标船型ME-GI低速机推进与TFDE电力推进2种最新的推进方式。结果可见，ME-GI低速机推进系统不论是经济性还是环保性都优于目前主流的TFDE电力推进系统，将成为未来大型LNG运输船的主流推进形式。
