A Study on the Estimation of Discharge Amount of Nox Emission from Ships in Port of Busan

Recently controlling of air pollutants emission from onboard ship as well as on land has become more important issue. New Annex VI to MARPOL 73/78 and IMO NOx Technical Code were adopted by the IMO. Particularly from the year 2000, according to Regulation 13 Nitrogen Oxides(NOx) of the Annex VI, this regulation should apply to new marine diesel engines greater than 130kW installed on vessels constructed on or after January 1, 2000, or which undergo a major conversion after that date and most of engines which are being currently built should be tested and surveyed in accordance with NOx Technical Code. On the other hand, in order to prevent the port city from air pollution, we have to know how many tons of NOx emit from ships in all port city and we should make our own implementation schedule depending on our country's status. In this paper, it was carried out the estimation of discharge amounts of nitrogen oxides(NOx) from all ships in the port. But it is difficult to survey for the discharge amounts of NOx from all ships in a port city due to time and cost. So this paper proposed the method of calculation without onboard survey. With the comparison and analysis of other countries emission calculation method, author proposed basic data of total discharge NOx emission from ships in the port and simple calculation method. Especially, this report focused on port of Busan, because marine traffic of Busan is very intensified.
