PROBLEM TO BE SOLVED: To provide a ship hull structure that enables a ship compliant with NOsecondary regulations to be easily modified to be compliant with NOtertiary regulations.SOLUTION: A device installation area for installing an exhaust gas purification system that reduces nitrogen oxide contained in exhaust gas is formed around an engine casing 14 on an upper deck 12. When the exhaust gas purification system is installed, a body 70 is provided at, for example, a starboard side of the engine casing 14. When the exhaust gas purification system is mounted, in the body 70. a low-pressure SCR reactor 51 is mounted on a first deck 71 positioned above the upper deck 12. A first low-pressure SCR pipe 52 connected to the low-pressure SCR reactor 51 is connected to a first branch part 34 of an exhaust pipe 26. A second low-pressure SCR pipe 55 connected to the low-pressure SCR reactor 51 is connected to a second branch part 35 of the exhaust pipe 26.SELECTED DRAWING: Figure 5

    【課題】NOX2次規制対応の船舶を、簡単にNOX3次規制対応の船舶に改修可能にすることができる船体構造を提供する。【解決手段】排ガスに含まれる窒素酸化物を低減するための排ガス浄化システムを設置するための機器設置領域を、上甲板12上であってエンジンケーシング14の周囲に形成する。排ガス浄化システムを設置する場合、本体70をエンジンケーシング14の例えば右舷側に設ける。排ガス浄化システムを搭載する場合、本体70において、上甲板12より上方に位置する第1の甲板71に低圧SCRリアクタ51を載置する。低圧SCRリアクタ51に連結される第1の低圧SCR配管52を排気管26の第1の分岐部34に連結する。低圧SCRリアクタ51に連結される第2の低圧SCR配管55を排気管26の第2の分岐部35に連結する。【選択図】図5
