Model of NOx emission by sea-going vessels navigating in the gulf of Gdańsk region

The development of marine diesel engines has so far been directed towards raising their power, reducing fuel consumptions, burning fuels of the lowest possible quality and the extension of operation time. The rising pro-ecologic pressure has caused atmosphere pollution by exhaust gases of marine engines to be one of the main problems of environment protection of recent years. The Gulf of Gdansk area, just like sea ports or coastal regions, is vulnerable to the effect of noxious compounds contained in vessel exhaust gases, besides those coming from industrial plants, power plants or vehicles. This concerns vessels both in ports and in the roads. In order to determine the share of vessels in environment pollution and counteract the harmful effects of toxic compounds in marine engine exhaust gases, it is necessary to know the emission values of these compounds from particular vessels, which is possible with the knowledge of their movement parameters, concentration values of particular compounds for these parameters and the atmospheric conditions. The report presents conditions concerning the modeling of noxious compounds emission in the Gulf of Gdańsk region.
