The article highlights the measures to be introduced in order to restrict the hazardous emissions from the marine vessels as a result of increasing attention of the global community to the air pollution problem. The most difficult for ship owners is to adhere to the requirements of MARPOL 73/78 in NECA Tier III. As a result of the analysis of modern widely used methods for reducing harmful emissions of nitrogen oxides from a marine ICE there have been determined the main advantages and disadvantages of these methods. A new method including the additional component supply system, which delivers additional component to an inlet manifold of a marine ICE, and the most suitable additional component were proposed. Main advantages of the proposed system over other systems were determined. The system operation diagram is presented and the academic novelty of the scientific work was determined. The academic novelty consists in using an adapted mathematical model for calculating the main parameters of the system developed. At the current stage of the work, the development of an electronic control unit for the system and additional electronic control unit is in progress. The next stage of the work consists of calculating the main parameters of the system and testing the system in various operating modes of marine diesel engine 3NVD 24
