Measurements of nitrogen oxides concentrations in exhaust gases of marine engines under various cruising are difficult or impossible to perform due to their cost and technical difficulties. Such measurements are generally performed on engines under static load conditions, which are determined by appropriate tests, and this is the basis for computing the values of indicators and characteristics of NOx emissions. The values of the following parameters are determined: specific emissions, emissions intensity, cruise emissions, as well as the propeller, regulatory, and adjustment characteristics of – most frequently – specific emissions. These indicators and characteristics are of limited use for the determining of the NOx emissions level in the exhaust gas of engines belonging to a set of different vessels operating in a given sea area which e.g. due to stricter environmental requirements requires reliable information about the current level of pollution. The authors have made a successful attempt at developing mathematical models in order to determine the resistance characteristics of the hull s of various ships and the power of their engines under different cruising conditions, and to estimate indicators and characteristics of NOx emissions on the basis of numerical simulation studies. The computer program developed allows for the examination of various vessel types, and their various sizes, cruising speed distributions, and changing external conditions (e.g. water density and depth, sea state etc.). The present paper will presented the course of the model's construction, the assumptions, and methods for determining the inter -relationships, and the results of numerical studies for a number of ships under various cruising conditions.
