In 2008 the International Maritime Organization - IMO decided to strengthen the requirements for new ships from 2011 - Tier II. However, for Emission Control Areas (ECAs), such as the Baltic Sea, stringent rules will apply from 1 January 2016 for new ships - Tier III. The new standards introduce restrictions on exhaust emissions from diesel engines - NOx and SOx. The paper presents proposal of new design an existing exhaust gas system of experimental marine diesel engine, which is situated in the Laboratory of Maritime Academy in Szczecin. The conception is due to meet to new environmental regulations. Arrangements of exhaust line, CFD model of the SCR reference plant, CFD model - inlet and outlet boundary conditions, pressure loss model for the catalytic elements, simulation results - streamlines, velocity distribution, reaction progress distribution ate presented in the paper as well design description of system of laboratory- 4-stroke and turbocharged engine. . The means of the reduction systems are based on conventional marine exhaust gas installation that includes noise silencer and soot-catcher. The after-treatment methods do not introduce significant changes in engine arrangement and operation. A new gas purifying system should be installed in the engine exhaust gas system.
