Shipping emissions are a significant source of air pollution, especially for coastal areas and harbor towns. The establishment of a Sulfur Emission Control Area (SECA) for North Sea and Baltic Sea by the International Maritime Organization has been a first step to control and reduce SO2 emissions by consecutively regulating the sulfur content of fuels.
Within the project MeSmarT, a collaboration between the University of Bremen and the Bundesamt für Seeschifffahrt und Hydrographie, a monitoring system for the sulfur content of ship fuels has been developed. The method is based on in-situ measurements of plumes of ships passing a fixed station at the river Elbe. In addition to SO2 and CO2, which are necessary for the sulfur content analysis, nitrogen oxides (NOx) and O3 are measured as well. After two and a half years of measurements a large dataset of more than 12000 plumes of ships has been acquired. Based on this dataset, the relations between the exhaust gas components as well as emission factors of different ship types and for various conditions will be presented.
