Currently, the Baltic Sea States suggests a proposal to designate the Baltic Sea as an Emission Control Area for nitrogen oxides, in accordance with Annex VI of MARPOL73/78. The emission would be estimated on the data produced by the AIS (Automatic Identification System) system that is compulsory for ships. Therefore, exhaust emission of the ships' can be computed using the actual speed and main propulsion shaft power. Mostly, main propulsion engines' exhaust emission is dependent to realistic performance and can be determined. The research plan has been prepared, aimed an evaluating the main propulsion engine performance and emissions. In cooperation with the ship owner, the experimental program onboard the container vessel, equipped with latest large bore, two-stroke, and slow speed MAN B&W electronic controlled engine was carried out. The records set of vessel speed and related engine shaft power, fuel consumption and exhaust emission for container vessel is formed. Taking into account; main engine performance, types of fuel and other input data, the emission factors were determined for ship sea service state. Main engine shaft power estimation and measurement setup, examples of main engine shaft power, the shaft power equation coefficients density, example of main engine service operation, fuel oil consumption group, the ship speed estimated form, example of main engine area operation influenced by weather conditions are presented in the paper.
