  • 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.

  • 지반이 산업용 기름으로 오염될 때 지반의 강도변화 특성을 연구하기 위하여 모래와 실트질 모래 및 카오리나이트를 대상으로 함수비아 함유비를 변화시키며 다짐실험, 투수실험, 비배수상태에서 삼축압축실험을 실시하였다. 실험결과에 의하면 밀도가 같은 모래의 경우는 기름을 혼합하였을 경우가 물을 혼합하였을 경우에 비해 약 7%정도 전단 강도가 떨어지고 실트질 모래와 카오리나이트 경우는 기름을 혼합하였을 경우가 물을 혼합하였을 경우에 비해 점토입자와 기름의 화학적, 물리학적인 상호 작용으로 5~15%정도 강도가 증가하는 현상을 보였다. 일반적으로 산업용 기름 유출에 따라 토양오염 및 수질오염으로 동.식물에 큰 영향을 주고 있으나 토질역학적 거동은 초기 상태 및 모래에서는 전단 강도가 감소하였으나 점성토의 경우는 기름 유출 또는 유입에 따라 응집성, 부착성이 생겨 강도증가 현상을 가져와 큰 문제점이 없는 것으로 판단된다.

  • Once oil has spilled, oil spill responders use a variety of countermeasures to reduce the adverse effects of spilled oil on the environment. Mechanical methods of containment and recovery are preferred as the first response when the use of other methods fail or are ineffective. In these cases, the application of oil dispersants shall be use only as a last resort. While effectiveness of dispersants in removing oil form the sea surface is proven, the use of dispersants is controlled in almost all countries due to the toxicity of their active agents and the dispersed oil on the marine environment. However, according to reports, after dispersant application, no significant toxicity to fish or shrimp was observed in the field-collected samples. Moreover, the results also indicate that dispersant-oil mixtures are generally no more toxic to the aquatic test species than oil alone. During the Deepwater Horizon Incident, dispersants were applied to floating oil and injected into the oil plume at depth. These decisions were carefully considered by state and federal agencies, as well as BP, to prevent as much oil as possible from reaching sensitive shoreline habitats. Net Environmental Benefit Analysis for dispersant use assumed that dispersants appear to prevent long-term contamination resulting absence of oil in the substrate and will benefit marine wildlife by decreasing the risk of significant contamination to feathers or fur. Further study to use dispersants with scientific baseline is needed for our maritime environment which consistently threaten huge oil spill incidents occurrence.

  • The purpose of this thesis is studying for a legal basis and definition of Oil Record Book. In the thesis, comparing with the laws related to punishment for false entry of Oil Record Book of the maritime countries and korea Act. Studying the improvement marine pollutants from ships by suggesting legal and institutional proposal which are able to make themselves increase effectiveness for recording and inspection of Oil Record Book. Suggest the solution of the problems raised in this thesis, First, The Oil Record Book should not be the evidence which is having the effectiveness simply after the accident of marine pollution, but take sanction on pre-inspection of Oil Record Book as establish the concrete administrative punishment for each contents-based record of Oil Record Book. Second, It should set up of judgement criteria of false entry of Oil Record Book by port state control officer. Third, It should strengthen the legal effectiveness of Oil Record Book contents such as Code(c) ; oil residue, Code(d); relating to bilge discharge by including premeditation for false entry of Oil Record Book. Also, The enhancement of role for marine pollution prevention manager raise the effectiveness of Oil Record Book as recognizing the importance of Oil Record Book.

  • In order to seize quantitative materials as part of studies on measures for oil pollution prevention and control, the statistics of oil pollution incidents in Korean coastal waters for 10 years from 2003 to 2012 were analyzed with relation to the number of oil spills and the volume of oil spilt according to causes, sources and sea areas of spills. Total number and total volume of oil spills for 10 years were found to be 2,833 cases and 17,877 kL, respectively. 50.4 %(1,429 cases) of total number of oil spills were caused by negligence, although oil spillage due to negligence was 294 kL(1.7 %). While oil spillage caused by marine accidents was 17,400 kL(97.3 %), marine accidents accounted for 27.9 %(790 cases) of total number of oil spills. While negligence had a great influence on the number of oil spills, marine accidents had a huge impact on the amount of oil spilt. Fishing boats accounted for 42.7 %(1,210 cases) of the number of oil spills, and although oil tankers accounted for 9.2 %(261 cases) of the number of oil spills, oil spillage from oil tankers was 15,488kL(86.7 %). It means that oil tankers such as VLCC or ULCC may be the main sources of major oil spills and a few very large spills are responsible for a high percentage of the amount of oil spilt. While the number of oil spill incidents was closely related to the accidents of fishing boats, the volume of oil spilt was greatly affected by the major oil spill incidents of oil tankers such as M/T Hebei Spirit. The number and volume of oil spills were shown to be 1,613 cases(56.9 %) and 3,804 kL(21.3 %) in South Sea, 700 cases(24.7 %) and 13,501 kL(75.5 %) in West Sea, and 520 cases(18.2 %) and 572 kL(3.2 %) in East Sea of Korea, respectively. The highest number of oil spills was found in South Sea and the most volume of oil spilt was shown in West Sea of Korea for 10 years.

  • In this study, the Hazard-based model to decide regional oil recovery capacity by using AHP is suggested and regional oil recovery capacity is calculated by applying the model. The simulation for oil recovery capacity by mobilization of regional oil recovery equipments is carried out to verify the availability of the model. The worst oil spill accident in Daesan Taean Pyeongtaek region, which is located in geographically disadvantageous position among the regions that the worst oil spill accident may occur, is supposed for the simulation. As a result of simulation, the quantity of oil that can be recovered for three days on the scene of oil spill accident is worked out as $15,841k{\ell}$, which can satisfy the goal of national oil recovery capacity for the worst oil spill accident, therefore the model is verified as practicable.

  • In order to obtain quantitative basic data for marine oil pollution prevention, the statistics of oil spill incidents in Korea and in the world for 20 years from 1993 to 2012 were collected and analyzed with relation to the number of oil spills and the amount of oil spilt. In Korea for 20 years, total number and average annual number of oil spills were 6,608 cases and nearly 330 cases/year, respectively, and total volume and average annual volume of oils spilt were 57,328 kL and nearly 2,866 kL/year, respectively. Due to major oil spills from oil tankers, annual volumes of oils spilt in Korea were sharply increased to 15,388 kL in 1993, 15,773 kL in 1995, 3,428 kL in 1997 and 13,008 kL in 2007. In case of worldwide oil spills for 20 years, total number and average annual number of oil spills of 8 kL (or 7 tonnes) and above were 420 cases and 21 cases/year, respectively, and total amount and average annual amount of oils spilt 8 kL (or 7 tonnes) and above were about 800,000 kL (or 704,000 tonnes) and about 40,000 kL/year (or 35,200 tonnes/year), respectively. Major oil spills from oil tankers increased massively annual amounts of oils spilt worldwide to about 159,000 kL (or 140,000 tonnes) in 1993, about 147,600 kL (or 130,000 tonnes) in 1994, about 90,900 kL (80,000 tonnes) in 1996, about 81,800 kL (72,000 tonnes) in 1997 and about 76,100 kL (or 67,000 tonnes) in 2002. Obvious correlation between annual number of oil spills and annual amount of oil spilt was not found in both Korea and the world, while both annual number and annual volume tended to decrease with the lapse of year in both Korea and the world, though there were wide fluctuations from year to year in both annual number of oil spills and annual amount of oils spilt worldwide and in Korea for 20 years. From 2008 to 2012 worldwide, there were sharp decreases in both annual number and annual amount of oil spills. In particular, no oil spill of 800 kL (or 700 tonnes) and above occurred in the year of 2012.
