Abstract
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 NO_x Technical Code were adopted by the IMO.


Particularly from the year 2000, according to Regulation 13 Nitrogen Oxides(NO_x) of the Annex VI, this regulation shall apply to new marine diesel engines greater than 130 kW 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 NO_x Technical Code.


In order to prevent the port city from air pollution, we have to know how many tons of NO_x emit from ships in all port city and we should make our own implementation schedule depending on our country's status.


For this purpose, this study investigates the discharge amounts of nitrogen oxides(NO_x) from all ships in the port. But it is difficult to survey for the discharge amounts of NO_x from all ships in a porty city due to time and cost.


Marine engine power is very related to Gross tonnage of ship and the amount of NO_x emission is related to engine power. Therefore the method of calculation can be obtained from these relationships.


So this report proposed the method of calculation without onboard survey. With the comparison and analysis of other countries emission control regulation, author proposed basic data of total discharge NO_x emission from ships in the port and future emission control standard in our country. Especially, this report focused on port of Busan, because marine traffic of Busan is very intensified.


From the Busan Regional Maritime Affairs and Fisheries office, ships types were classified into container ship, bulk carrier, general cargo ship, passenger ship.


Marine engine power is directly related to Gross tonnage of ships therefore aregression across four ship types was performed by using KR registration data statistically.


As the result, the estimation results reveal that total discharge amount from ship is large unexpectedly , but there is few report that NO_x emission from ship will have an effect on the coastal environment. Thus its effect should be investigated in order to search the proper procedures against air pollution.


The more study will need to research OCD(Offshore and Coastal Dispersion)model for coastal environment effect.
