[PROBLEMS] To maintain the temperature of a reducing agent such as urea water within an appropriate storage temperature range even when the outside air temperature or the engine room temperature becomes high, and prevent a reduction in the life of the reducing agent. Provided is a ship provided with a NOx reduction device capable of shortening the distance between an exhaust gas exhaust path from an internal combustion engine and a reducing agent tank. In a ship provided with a NOx reduction device provided with a selective catalytic reduction catalyst for purifying NOx in exhaust gas G discharged from an internal combustion engine mounted on the ship, the selective catalytic reduction catalyst is supplied. A cofferdam 31 is provided on a part or all of the outside of the reducing agent tank 21 for storing the reducing agent R to be formed as a tank with a hull, and is configured to allow water to pass through the cofferdam 31.
