Port of Busan is Korea's largest trading port processing over 18,000 TEU a year. This rapid growth causes air pollution problems in Busan. Ship emissions are significant air pollution sources and port area is relatively close to the business district, therefore it may have serious effects to the health of local people and environment. In this study, ship emissions are estimated, especially on hotelling large vessels. As a result, Port of Busan has 50,686, 48,842 ship calls and 2,343,037 and 2,297,118 tons of ship emissions in 2011 and 2012 respectively. Also, the environmental cost in Port of Busan is approximately 1.2 trillion won per year. This study emphasizes the necessity of ship emissions regulation, hence, it is expected to make a significant contribution in setting up ship emission management system.

국제해사기구(IMO)에서는 황산화물(SOx)에 대한 배출 규제를 강화하고 있다. 2020년 1월 1일부터는 황함유량 0.5% 이하 선박연료유 사용을 의무화하고 있다. 그리고 온실가스 배출량 모니터링을 2019년 1월 1월부터 시행하여 총톤수 5천톤 이상 선박은 연료유 사용량을 의무적으로 보고해야 한다. 또한 배출통제구역(Emission Control Area, ECA)이 확대되고 있으며 지역별로도 저유황유 사용 의무화를 도입하는 항만이 증가하고 있다. 이와 같이 항만구역에서 선박 배기가스 배출 규제를 강화하고 있다. 본 연구에서는 컨테이너 물동량이 증가하고 있는 서산 대산항 컨테이너 부두를 중심으로 항만구역에서 배출되는 배기가스를 산출하였다.

The International Convention for the Control and Management of Ships Ballast Water & Sediments was adopted by consensus at a diplomatic conference of IMO at 2004. To prepare the Ballast Water Management Convention, fundamental technologies such as treatment system, type approval, risk assessment and various technical informations for formulation of the regulation for national strategy shall be developed. The information item of voyage and discharge of ship's ballast water are gathered by visiting vessel and agent at port. Using the 97 results by ships type characteristic analysis on the relation between loading/unloading and discharge/uptake of ballast water, the amounts of discharge/uptake of ballast water at each port and all of country in Korea are predicted. Hence, It is apparent that the uptake of ballast water is predicted to about 70 million ton in total of Busan, Incheon, Kwangyang and Ulsan ports at 2006 which is over 3 times than discharges.

As interest in environmental pollution caused by ship emissions is increasing worldwide, many studies are being conducted on the development of systems that increase energy efficiency to reduce ship emissions. In order to test the energy management system controller driven in real time on a large ship, it is necessary to perform the test through the simulator. In this study, addresses were set for each signal according to Modbus TCP/IP so that each control system and energy management system could be linked, and the algorithm was configured according to the signal flow. In addition, the signal generator was designed and manufactured so that each controller could artificially generate the signal collected from the vessel. As a result of the simulator production and interlocking, it was confirmed that each controller operated in real time performed its role appropriately, and that the algorithm of the ship energy management system was properly applied.

보다 깨끗한 환경에서 살고 싶어 하는 인류의 욕구가 육상의 대기 배출물뿐만 아니라 선박까지도 보다 깨끗한 배기를 요구하기에 이르렀다. 이러한 요구에 부응하여 IMO(국제해사기구)뿐만 아니라 EU(유럽연합)과 미국 등에서 규제를 이미 시작하였거나 시작할 예정이다. 또한 많은 선급에서도 약 10년 전부터 자발적인 규칙을 도입해오고 있다. 그리고 스웨덴은 인센티브제를 오래 전부터 적용해오고 있다. 이러한 규제, 선급 규칙 및 인센티브제는 질소산화물, 황산화물 및 입자상물질 배출에 제한을 가하는데, 황산화물 및 입자상물질 배출 제한은 간접적으로 연료유에 함유되어 있는 황 함량 규제를 통하여 하고 있거나 하려고 한다. 여기에 이러한 규제, 선급 규칙 및 인센티브제에서 가하고 있거나 가할 예정인 선박 디젤기관 연료유의 황 함량 규제에 대하여 간략하게 소개한다.

This study was focused on the estimations of air pollutants, such as PM(Particulate matters), SOx(Sulfur Oxides), $CO_2$(Carbon diOxides) and NOx(Nitrogen Oxides), from a diesel propulsion engine installed on a naval vessel. Legislative and regulatory actions for exhaust emissions from ships are being strengthened in international communities and national governments to protect human health and the environment. In this context, various technologies have been developed from all of the nations of the world to meet strict standards. These regulations are based on commercial ship applications and according to size, but are not suitable for military naval vessels, which have much different engine operating conditions and hull architectures. Additionally, there is no international emission control system for military ships. Emission factors have been updated for commercial ship types from work at various research institutes; however, it is difficult to develop emission factors for military vessels because of their characteristics. In this paper, exhaust emissions from diesel engines installed on naval vessels under steady navigation condition were estimated with emission inventory methodology applied to ocean going vessels using fuel-based methods and fuel sulfur content analysis.

A thorough inventory of ship emissions, particularly ship's emission of in-port area is necessary to identify significant sources of exhaust gases such as NOx, SOx, PM, and CO₂ and trends in emission levels over time, and reduce their serious effects on the environment and human health. Therefore, the goal of this study is to assess the volume of emissions from ships in Mokpo port, which serves as a gateway to the southwest coast of Korea, using a bottom-up methodology and data from the automatic identification system (AIS) and the Korean Port Management Information System (Port-MIS). In this work, an analysis of ship movement utilizing AIS data and an actual set of data on ship specification were gathered. By examining ship movement using AIS data, We also proposed a new approach for identifying cruising/maneuvering mode. Finally, the results were classified by ship operating mode, by exhaust gas, by ship type, and by berth, which provides a thorough and in-depth analysis of the air pollution caused by ships in Mokpo port.

Nitrous oxide ($N_2O$) is naturally generated from biological activity, such as bacteria's material exchange. However, recent $N_2O$ concentration in the atmosphere has being increased by the human activities such as industrial growth. One of factors to increase $N_2O$ concentration in the atmosphere is a $N_2O$ emission caused by the combustion of marine fuel oils. The marine transportation presently handles over 99 percent of the international freight cargoes and the number of ship is continuously increasing with increment of cargoes. In this study, author conducted a series of the experimental investigations on which combustion of fuels containing different element concentrations used in a 4-stroke marine diesel engine affect $N_2O$ emissions in the exhaust gas. Moreover, it is assessed on the extent to which fuel combustion patterns in the combustion chamber affect $N_2O$ emissions.
