  • Though stringent guidelines are in place to protect the harbor environment, pollution from ships, from the ports terminals. Discharge from the ballast tanks of ships, though illegal, does occur. Such vessels, arriving from distant ports of call, can introduce exotic species of plants and animals, causing disruption of the local food web. Discharges rich in nitrogen can generate the rapid growth of plankton, eventually leading to a condition known as red tide that is lethal to some coastal organisms. In addition to the harbor's negative effects on marine organisms, the diesel engines of the ships and the trucks that haul cargo to and from the ports release large volumes of diesel exhaust into the atmosphere. IMO(International Maritime Organization) is strongly proceeding with adoption of a new maritime environment convention and coming into effect for regulation enhancement about the pollutants which are happened in a ship recently. Study about the conventions that our country currently comes into effect, and there is during forwarding and correspondence must be performed effectively. In this paper, International convention on the control of harmful Anti-Fouling system on ship, Ballast water management, Prevention of air pollution from ships, treat a main pending problem in ocean related environmental regulation convention.

  • 환경문제에 관한 관심이 급속히 증가하고 있는 가운데, 1995년 여름 유조선 씨 프린스호의 여천 앞바다 좌초로 다량의 기름이 유출되었다. 이 사고 이후 두달이 채 지나기도 전에 유조선 제1유일호가 부산 앞바다에서 침몰하는 사고가 발생했다. 통계1)에 의하면, 1991년 1월부터 1995년 9월말까지 우리나라 연안에서 총 1,583 건의 오염사고가 발생하였고, 유출량은 22,541톤, 피해금액 3,231억원으로 집계되었다. 해양오염사고중 기름에 의한 오염사호는 총발생건수의 92%로 대부분을 차지하고 있다. 배출원인은 선박사고가 전체 발생건수의 87%, 육상 및 해양시설에 의한 사고가 10.5%, 배출원인 불명이 2.5%였다. 오염물질 중 기름의 종류별 유출랑은 경유 6,509톤, 벙커유 3,928톤, 선저폐수 759톤으로, 경유가 가장 많고 다음으로 벙커유가 많았다. 해상 기름유출사호는 기름운반선 등에 의해 하루에 한번 꼴로 크고 작은 기름유출사고를 일으키고 있으며, 발생건수가 매년 증가하고 있다. 우리나라 연안에서의 유류 해상 수송량 증가와 선박의 대형화로 대형기름유출사고의 발생 가능성이 잠재하고 있다.

  • 전 세계 국제무역거래의 80%가 해상운송으로 이루어지고 있음에 따라, 연 6%로 세계 컨테이너 물동량의 증가가 전망됨에 따라 선박기인 온실가스의 증가에 대한 관심과 규제가 강화되고 있다. 즉 IMO 제62차 해양환경보호위원회에서 선박기인 온실가스 규제방안으로 EEDI와 SEEMP를 도입, 현재 발효 중에 있으며, 각 국의 항만당국 또한 대기오염 등의 환경규제 정책의 일환으로 그린 또는 에코포트 정책을 수립하여 이행 중에 있다. 이러한 해운환경의 변화로 인하여 해운선사는 글로벌 경쟁력 강화와 환경규제에 대응하기 위하여, 선박의 대형화를 통한 규모의 경제 실현은 물론, 급등하는 유가와 환경규제에 대비하여 고 에너지효율 및 저탄소 선박에 대한 수요가 늘어나고 있다. 이에 일본, 싱가폴, 노르웨이 등 EU 국가 등의 해운 선진국들은 1990년대 후반부터 친환경 선박의 개발에 대한 국가적 프로젝트를 체계적으로 이행해 오고 있으며, 이를 통한 친환경 선박기술의 확보와 친환경 선박시장의 점유율을 높이고 있는 추세이다. 따라서 본 논문은 선진 해운국가들이 수행중인 친환경 선박개발의 현황에 대한 벤치마킹을 통하여 상대적으로 뒤쳐져 있는 우리나라 친환경 선박개발 방안을 위한 여러 정책적 제안을 하고자 한다.

  • 본 연구에서는 선박에서 발생하는 휘발성유기화합물을 처리하기 위하여 친환경적인 대기오염방지설비를 개발하기 위하여 유용미생물 담체를 충전한 바이오필터를 사용하여 VOCs가스를 처리하는 실험실 규모의 실험을 수행하였다. VOCs가스의 온도, pH, 습도, 가스농도와 VOCs가스 제거효율과의 상관관계를 도출하고 이를 바탕으로 바이오필터의 전반적인 VOCs가스 제거효율 및 수명 그리고 안정성 등을 평가하였다. 최적 조건에서의 VOCs 제거 효율은 유입되는 오염가스 농도가 2000ppmv까지 모든 범위에서 90%이상의 제거효율을 나타내는 것으로 보아 이 범위에서 안정적인 운전이 가능한 것으로 평가된다.

  • 국제해사기구(IMO: International Maritime Organization)의 선박 조종성능에 관한 기준이 발효되고, 최근 환경에 대한 관심이 지속적으로 증가하는 것과 더불어 항해 안전성, 특히 해난사고에 기인한 해양오염 방지에 관한 관심이 증가함에 따라 초기 설계단계에서부터 선박의 조종성능을 정확히 추정하는 것이 매우 중요하게 되었다. 본 논문에서는 선박 조종성능을 추정할 수 있도록 선박 고유 조종 운동 특성을 선박운항에 관련한 항해센서와 함께 선박 운항에 동일한 운전 조건으로 구성하고 HILS(Hardware In the Loop Simulation)을 적용하여 선박조종 신뢰성을 향상 시킬 수 있는 방법을 제시한다.

  • 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.

  • The Protocol adopted in Sep. 1997 included the new Annex VI of MARPOL 73/78, which entered into force on 19 May 2005. Revision for the accept MARPOL Annex VI with make public on 29 Dec. 2005 and enforce on 29 Jun. 2006. For all that not installation at oil terminal or if installed do not used. The purpose of this study is to research and evaluate the methods of sampling and analysis, and the pollution measure of existed VOCs during the bulk liquid cargo operation at vessels. As the sampling instrument of VOCs, Tedlar bag has the effect of decrease in concentration by the chemical reaction and absorption, and the method using the solvent extraction has error cause because of the extraction, the absorption tube has error by the breakthrough. But canister is the best sampling instrument because of having no sampling mistake. The study on VOCs emission is not sufficient for the research on the pollution cause and the analysis data on the HAP during the bulk liquid cargo operation at vessels. Hence, monitoring on the management hazardous VOCs need to be continued during the cargo operation at vessels and VOCs management field must be study for the make progress at a good pace for reason of crew's health.

  • Recently, air pollution from the marine ports has become a serious issue all over the world. Because marine trade accounts for 99.7% of Korea's trade, efforts are required to recognize the level of port pollution and establish environmental policies. This study estimates air pollution emitted during the berthing process in the Gwangyang and Ulsan ports. Data on ship activity and characteristics are collected and reasonable methodologies and factors from EEA and EPA are adopted. The results show that 253.09 tons of CO, 1986.61 tons of NOx, 684.01 tons of SOx, 47.88 tons of $PM_{10}$, and 44.69 tons of $PM_{2.5}$ are emitted at the Gwangyang port. Further, the Ulsan port emitted 212.28 tons of CO, 1712.54 tons of NOx, 573.72 tons of SOx, 40.16 tons of $PM_{10}$, and 37.48 tons of $PM_{2.5}$. A stage-by-stage plan for installing AMP infrastructure is suggested as part of a green port policy. This research provides the current pollution status and contributes guidelines for the direction of future policy.

  • Traditionally, UNCLOS stipulates that States have the obligation and responsibility to protect and preserve the marine environment and exercise their rights in Principle of Non-Discrimination with respect to foreign ships visiting to port states. UNFCCC and Kyoto protocol established Common but Differentiated Responsibility as the basis which is established on the historic responsibility. The principle in which IMO is presently developing the regulations of Green House Gas emitted from ships is contradict with the principle of UNFCCC regime. In this paper, the development and the principle of UNFCCC and Kyoto protocol is surveyed and it provides the tendency of the IMO activities regarding GHG emission from ships. Also, through consideration of the problems and restrictions drawn from comparison between two principles, the conclusion suggests the fundamental theory and implementation means in order to carry out the purpose of IMO regulations in accordance with the principles of UNCLOS and IMO Convention.

  • 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.
