Air pollution has become an important challenge worldwide over the few decades owing to rapid urbanization and industrialization. Among the various sources of measured emissions, the proportion of air pollutants from oceangoing vessels is increasing. In response, the Ministry of Oceans and Fisheries introduced the Vessel Speed Reduction (VSR) program in December of 2019. In this study, we used actual operational records from a 4,600 TEU container vessel to calculate its total emissions on its journey from the Port of Busan to the Port of Tacoma in the US and then compared the emissions generated in four scenarios to determine the optimal operating conditions. Among air pollutants, emissions were calculated only for TSP, PM<SUB>10</SUB>, PM<SUB>2.5</SUB>, NMVOCs, and CO, which are typically related to the occurrence of fine dust. To simplify our analysis, operating records from the same conditions as the 4,600 TEU container ship were applied to the 10,000 TEU container vessel and 7,500 CEU Pure Car and Truck Carrier (PCTC) to calculate emissions. A bottom-up approach was adopted and air pollutant emissions from the operational scenarios compared according to the results of calculations. Optimal results were not obtained in all scenarios when the speed suggested by the VSR program was applied. This is because of a speed decrease in the maneuvering mode caused by a fixed operating time of 505.5 h, resulting in an increase in speed in the cruising mode. Based on these results, improvement measures are proposed to reduce air pollutant emissions from ships.
