Abstract
A inject gas control device that performs, for example, control reflecting variation in vessel velocity over time without adversely affecting the main engine is realized. That is, it is prevented that gas is drawn too much and thereby a gas supply or charged air rate becomes insufficient, efficiency of the main engine is decreased and exhaust gas is deteriorated, and analogous events occur because the gas supply or charged air rate is too much instead. There are provided a main engineacquiring propelling power for a vessel, and a turbochargerthat is driven by exhaust gas from the main engineand blows pressurized gas to the main engine. A part of the pressurized gas and/or exhaust gas is drawn from between the turbochargerand the main engine(and). The drawn pressurized gas and/or exhaust gas are injected in the proximityof the hull on or below the waterline (), and the drawing rate of the pressurized gas and/or the exhaust gas is controlled on the basis of a physical quantity related to a heat load on the main engineand characteristics of the turbocharger ().
