  • The oil spill accident near Goeje Island on April 3, 1997 was analyzed using two RADARSAT SAR images. The first scene was acquired 3 days after the accident as an extended low beam mode and the second scene was acquired 12 hours after the first scene as a standard beam mode. The two scenes showed slicks not only by oil spills but also by oil spill look-alikes caused by wind sheltering, low wind, natural film, and etc. These slicks were analyzed and classified, and natural films produced from aquaculture farms around Goeje Island were also suggested as a strong candidate for slicks on SAR images. The study with two SAR imags indicated the oil spill patterns which spreaded to the southwest immediately after the accident and switched the direction to the east. The spreading patterns shown in two SAR images also showed good agreement with in-situ observations.

  • Tankers have somewhat different shapes in construction and working condition compared with normal merchant ship. If an accident occurs, normal merchant ship's damages will mostly be confined to ship and cargo, but those of tankers will result in oil spills and catastrophic loss beyond our imagination. So, first we must understand risk factors, pre-loss control and post-loss control, legal regulations about its indemnification and marine insurance for oil tanker operation. When unexpected accidents happen, despite pre-loss control, it is possible to cover those kinds of losses by insurance. To control these losses, however, it is important to establish compensation for oil pollution and arrange for oil pollution preventing system. In spite of these oil pollution preventing systems, we have rarely seen that pollution from oil tankers could be solved. So this paper was studied more fundamental and overall control measures for the risk management of oil tanker operation.

  • 전 세계적으로 해양으로 유입되는 유류의 유입량은 년간 약 2,350,000 들이며, 대략 15%는 자연적인 유입원이고, 85%는 인위적 유입원으로 유조선 사고, 정유공장, 도시 및 공장 폐수, 자동차 배기가스로 인한 것이다. 유입된 유류는 해양미생물이나 어류, 갑각류 등의 유생, 해양 포유류 등 해양 생물에 피해를 주어 생태계를 파괴시키며 인간의 연안활동이나 어업과 양식에 경제적 피해를 입히기도 한다. (중략)

  • 본 조사를 통해 토양오염유발시설 중 유류 유출사고가 잦은 주유소에서의 오염현황 조사방법과 오염토양에 대한 적정한 정화기법을 제시하고자 하였다. 오염현황 조사결과, 지층구조 는 전반적으로 Clay로 구성되어 있으나 오염토양 주변은 비교적 투수도와 통기성이 우수한 Silty Sand층을 나타내고 있었다. 본 주유소의 경우 주유기 주변(상층부)과 지하유류저장탱크 주변(수직분포)에 오염이 분포되어 있고, 오염원인은 주유기의 배관 파손 및 결함에 의해 발생한 것으로 예상된다. 본 조사지역에 대한 정화기법으로는 토양증기추출기술(SVE)과 불포화대를 생물학적으로 복원할 수 있는 바이오벤팅기술을 결합시킨 Bioslurping이 효과적일 것으로 평가된다. 또한 Bioslurry injection treatment를 병행하여 효과적으로 고농도의 오염토양을 처리하는 것이 바람직할 것으로 판단된다.

  • When large-scale oil spill happens, it will put the fatal impact on the ecosystem, ultimately harm human being seriously. Accordingly every coastal country invests to improve response technologies, of which oil removal by use of bioremediation agent is taken to be secondary or alternative cleanup method in a specific spilled area In this regards, the author attempts to find out the efficiency and effectiveness of bioremediation agent to oil slick by laboratory experiment as well as the possibility of bioremediation application to future spill accident and gets the some results. In this study, the effectiveness and efficiency of bioremediation agent to oil slick is examined by short-term laboratory test and it is found that bioremediation agent am degrade oils effectively. however, considering the environment c! spill site is quite different from that of lab, the author will carry on the on-scene test of bioremediation for longer period to look into the possibility of biorediation agent as one of oil spill response methods.

  • 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.

  • According to grow maritime activities in coastal zone, a threat increase to the marine environment from oil spill. The success or failure of initial effort depends on the adequacy of the plan and the ability of immediate execution. Successful response to oil spills requires critical information in real time topics, including spill data, environmental conditions, ecological factors. Diverse simulation provides tactical decision-makers with the information on the movement of pollutant.

  • After oil outlow accident of Hebei spirit in December 7, 2007, the motality of manila clam, Ruditapes philippinarum in the west coast of South Korea, was significantly increased from 9.2% in April, 2007 to 22.4% in April 2008. Although the mortality was about 10% in the tidal flat of Geunso Bay and Cheonsu Bay, Incheon and Gyeonggi-do, the values was significantly high about 30% in water coast of Taean, Boryeong and Seosan in where the spilled oil was getting into fishery zone. However, the mortality in water coast of Taean, Boryeong and Seosan was decreased from 22.4% in 2008 to 6.0% in 2009. Also, we found that the mortality in contaminated and non-contaminated water zones was both slightly increased from 6.0 in 2009 to 8.6% in 2010, Therefore, these results are indicating that the significant high mortality observed in water coast of Taean, Boryeong and Seosan at April, 2008 was due to the crude oil accident outflow from tanks of Hebei spirit. Although the mortality of manila clam was significantly decreased in middle west coast of South Korea after the accident of Hebei spirit in December, 2007, the annual production of manila clam in South Korea was sustainedly from 27,459 ton in 2007, 36,302 ton in 2008, 40,392 ton in 2009, to 36,248 ton in 2010. In the production of manila clam by regional groups, the amount in sea coast of Chungnam, where was damaged by crude oil, was significantly decreased from 10,598 ton in 2007 to 5,048 ton in 2008, but then was significantly increased to 7,065 ton in 2009, and to 12,921 ton in 2010. However, in sea coast of Jeonnam that was not damaged by crude oil, the amount was significantly increased from 1,252 ton in 2007 to 12,248 ton in 2008, but then was significantly decreased to 9,566 ton in 2009, and to 2,770 ton in 2010. Therefore the results are suggesting that a increasing of the total annual production of manila clam in South Korea in 2008 when was 1 year after the oil accident of Hebei spirit was due to increasing of clam production in a coast of Jeonnam in where was not damaged by crude oil.
