PROBLEM TO BE SOLVED: To sufficiently ensure the output in a direction inverse to a travel direction during the crash operation while reducing the harmful substance in exhaust gas in an EGR system and an operational method of a vessel.SOLUTION: An EGR system comprises: an exhaust gas recirculation lines G5, G6, and G7; an EGR inlet valve 41 and an EGR outlet valve 45; a scrubber 42; and a control device 80 that is ready to opening/closing control the EGR inlet valve 41 and the EGR outlet valve 45 while being ready to drive control the scrubber 42. The control device 80 is ready to execute an EGR operation emergency stop mode in which when a crash operation signal is input, the EGR inlet valve 41 and the EGR outlet valve 45 are closed.SELECTED DRAWING: Figure 1
【課題】EGRシステム及び船舶の運転方法において、排ガス中の有害物質を低減することができると共にクラッシュ操作時に進行方向とは逆方向の出力を十分に確保することができる。【解決手段】排ガス再循環ラインG5,G6,G7と、EGR入口バルブ41及びEGR出口バルブ45と、スクラバ42と、EGR入口バルブ41及びEGR出口バルブ45を開閉制御可能であると共にスクラバ42を駆動制御可能な制御装置80とを備え、制御装置80は、クラッシュ操作信号の入力時にEGR入口バルブ41及びEGR出口バルブ45を閉止するEGR運転緊急停止モードを実行可能である。【選択図】図1
