VESSEL, AND POWER SYSTEM AND OPERATION METHOD FOR THE SAME

To provide a vessel capable of stopping an exhaust emission control device without stopping all generators while avoiding complication of a piping structure of an exhaust flow passage as much as possible, and a power system and an operation method for the same.SOLUTION: A vessel includes: a plurality generators 4; an exhaust flow passage 12 where exhaust gas exhausted from the generators 4 flows; and an exhaust emission control device 8 installed in the exhaust flow passage 12. A bypass passage 16 for conducting the exhaust gas from a generator 4a, which is one of the generators 4, outside the vessel by bypassing the exhaust emission control device 8 in the exhaust flow passage of the generator 4a.SELECTED DRAWING: Figure 2 【課題】排気流路の配管構成の複雑化を極力避けつつ、全ての発電機の停止を伴わずに排気浄化装置を停止させ得る船舶及びその動力システム及び運転方法を提供する。【解決手段】複数の発電機４と、該発電機４から排出される排気ガスが流通する排気流路１２と、該排気流路１２に設置された排気浄化装置８とを備え、複数の発電機４のうち一部の発電機４ａの排気流路に、発電機４ａからの排気ガスを排気浄化装置８を迂回させて船外へ導くバイパス流路１６を備える。【選択図】図２
