The purpose of the present invention is to provide: an exhaust purification system capable of suppressing a discharged NOx amount to no more than a NOx limit and of selecting a combination of means for decreasing NOx in accordance with the operation state of an engine and the state of the exhaust purification system; and a ship comprising same. The exhaust purification system for the engine (1) has a reduction catalyst provided inside an exhaust pipe (3) for the engine (1) and is configured such that: the NOx discharge amount relative to the operation amount of a Means for decreasing NOx for the engine (1) is calculated on the basis of the operation state of the engine (1); the NOx reduction amount relative to the spray amount of a reduction agent is calculated on the basis of the operation state of the engine (1); and a combination of the reduction agent spray amount and the operation amount of the Means for decreasing NOx is calculated such that the difference between the NOx discharge amount and the NOx reduction amount is no more than the NOx limit.
