Abstract
A ship comprises: a hull; an engine for propelling the hull; a harmful substance reducing device for reducing harmful substances included in exhaust gas discharged from the engine; and a preheating device for the harmful substance reducing device, preliminarily heating the harmful substance reducing device when the hull is located at an emission control area (ECA) preliminary entry point close to an ECA in which the emission of the harmful substances is restricted. The ship comprises: the hull; the engine for propelling the hull; the harmful substance reducing device for reducing the harmful substances included in the exhaust gas discharged from the engine; and an engine output control device for controlling the output of the engine to be lowered so as to reduce the amount of the exhaust gas discharged from the engine when the hull is located in the ECA or at the ECA preliminary entry point.
