Analysis of Emission Characteristics and Estimation of Air Pollutants Emitted from Small Ship

Abstract

Regulations on domestic ports and ships have been in progress in accordance with regulations established by IMO (International Maritime Organization), but most of them have only aimed at large vessels more than 400 tons or a capacity of 130 kW. However, the IMO regulations are hardly applied to a port situation in Korea because more than 90% of the ships registered in Korea are considerably small less than 10 tons. The air pollutants emission released from the ships are estimated only based on regional fuel consumption and emission factors, but it is also noted that the emission characteristics of automobiles show various emission characteristics depending on the operating conditions. Thus, it is assumed that the emission characteristics of the ships are also determined by the operating conditions, but the associated data in this aspect are still insufficient. This study aimed to investigate the effect of the operating conditions of the ships less than 10 tons on the characteristics of the air pollutants emission. The results showed that more amount of NOx and particle material were discharged in the low-speed regions whereas high-speed regions emitted more amount of CO and CO2. Moreover, the NOx emissions estimated by the field study were approximately 20 times higher than the NOx emissions of fishing ship in South Chungcheong Province based on CAPSS (Clean Air Policy Support System). This indicated that the previous activity-based data were underestimated compared with the actual emissions. Future studies should collect more data to verify the accuracy of these results. Furthermore, emission factors should be estimated for each operation condition based on the collected data to calculate the national emissions as accurately as possible.
