Using dispersants is known to be an effective solution to accelerate the natural dispersion and being an appropriate oil spill response strategy. By breaking up large oil chunks into small droplets, dispersants are generally intended to help reducing further oil exposures and slicks. Collecting property data of circulating crude oil in South Korea and understanding the interaction between crude oils and dispersions need to be preceded for the effective dispersant use. This paper provides an property analysis of three selected oils which have the same composition of spilt oils from the Herbei Spirit Incident and conducts an emulsification and toxicity experiment with selected domestic and foreign dispersants. Results will present a direction of future domestic dispersants' development which aimed at eco-friendly and safety.

The provability of major oil spill acidents around Korean coast is very high due to increase of sea traffic and decrease of quality of ships crews and increase of the old-ship. The Strategies of establishment of a advanced response management system against this mass pollution incident are as follows;. 1. Development of Regional Contingency Plan, which is scientifically illuminated, in order to implement the National Contingency Plan efficiently. 2. Early completion of a national response capability twenty thousand tons. 3. To strengthen training and exorcise specialized in the field of marine pollution response. 4. Establishment of a system of response cooperation among neighbor countries by promoting the NOWPAP tasks etc. The response policy in the 21th century should be concentrated to promote a practicle response capability through response operation scientifically specialized and internationalized by establishing the advanced response system early.

In this paper recently catastrophic oil spills from tanker casualties have polluted the marine environment. The Sea Prince casualties are analyzed and the systems to be introduced are considered. Also, the establishment of the national contingency plan and the decision-making procedure based on technical analysis are described. Based on the discussions the Rapid Response Technical Support System is derived for the support of salvage and oil spill removal operation. The System will contribute to the protection of life and assets from the marine casualties and to keeping the clean and safe ocean.

대형 유조선에서 기인된 1995년 Sea Prince호 및 2007년 Hebei Spirit호 사고 등 대다수의 재난적 유류유출사고는 많은 변수 중 "악천후"라는 기상적 어려움으로 초동방제활동 및 피해규모의 축소가 어려운 실정이다. 하지만, 정작 사고선박에서는 방제활동 주도기관의 개업이 있기 전까지 적극적인 방제활동이 이뤄지지 못하고 있는 실정이다. 사고선박에서 유출되는 유류의 확산범위 및 이동방향에 대한 정보는 추후에 예정된 방제활동에 있어서 가장 중요한 요소 중 하나이다. 이 중요한 정보의 획득을 위해 사고선박에서 설치가 가능하며, 이후 방제활동에 중요한 유출유의 확산 정보를 제공할 수 있는 유류확산 추적부이 (NOST-Buoy)의 개발연구가 필요하다.

효율적인 방제전략 수립 지원시스템 개발의 일환으로 환경민감정보 기반 실시간 유출유 확산예측 시스템과 피해위험도 예측시스템을 연계한 해양오염 방제지원시스템을 개발하였다. 실시간 유출유 확산예측시스템에서는 실시간 바람과 실시간 해수유동을 기반으로 유출유의 이동을 계산하고, 유출유 특성에 따라 해상 유출유의 풍화작용을 모델링하여 유출유의 잔류량 및 확산분포를 계산한다. 유출유 확산 예측의 실시간 바람은 국립환경연구원의 실시간 기상모델 결과를 FTP를 이용하여 실시간으로 연계하여 활용하며, 실시간 해수유동으로서 조류는 수치모델결과와 검조소 관측결과의 결합을 통해 실시간 조석을 예측하는 CHARRY (Current by Harmonic Response to the Reference Yardstick) 모델을 이용하여 예측하고, 실시간 취송류는 바람과 취송류간의 상관관계와 반응함수를 이용하여 예측한다. 실시간 해수유동을 따라 이동하면서 풍화되는 유출유의 풍화작용은 유출유 특성에 따라 결정된 감소율을 적용하여 모델링한다. 본 시스템은 이와 같은 정보를 ESI(Environmental Sensitivity Index) 및 방제자원 정보와 통합하여 종합적으로 제공함으로써 방제전략 수립을 지원한다.

An oil boom was set up in order to contain diffused oil from spills and for the retrenchment of damage caused by oil Pollution. Therefore, the oil boom anchor needed proper holding power to endure high resistance from flowing streams and to secure the oil boom around the spill, and must dredge directly into the seabed when it is dropped and block oil outflow immediately. This study investigated the holding power of the danforth anchor and the coastal fishing vessel anchor used for oil booms in the KMPRC (Korea Marine Pollution Response Corporation). For each type, a 30 kg and 20 kg anchor were used. The holding power of the danforth anchors were measured by dropping both weights 10 times. However the coastal fishing vessel anchors were dropped only 5 times each, because no substantial differences were found between drops. In the results of the danforth anchors, an anchor awoke occurred in 2 drops of the 30 kg anchor and in 4 drops of the 20 kg anchor, wherein there was no holding power to be measured. With exception to the anchor awoke cases, the maximum holding power of the danforth 30 kg and 20 kg anchors was 250-520 kg and 123-233 kg, respectively. In the case of the coastal fishing vessel anchors of 30 kg and 20 kg, throughout the experiment, there was no occurrence of an anchor awoke. For the 30 kg and 20 kg anchors, the maximum holding power was measured to be 209-230 kg and 155-170 kg, respectively. Therefore, the holding power of the coastal fishing vessel anchor was shown to be much poorer than that of the danforth anchor. However, the holding power of the danforth anchor was very unstable. Due to the occurrences of anchor awoke, there was no holding power and the measurement value of maximum holding power showed too much variation among the drop tests. Also, after the maximum holding power was achieved, anchor awoke occurred easily. In the case of the coastal fishing vessel anchor was much more stabile, because there was no anchor awoke and no instance where holding power failed. Also the maximum holding power was reached quickly and almost no variation occurred among the drop tests.

As a plan for oil spill accidents, research to collect and analyze optimal equipment assignments is essential. However, studies that have diversified and analyzed the optimal equipment assignments for responding to oil spill accidents have not been preceded. In response to the need for analyzing optimal equipment assignments study, we devised a genetic algorithm for optimal equipment assignments. The designed genetic algorithm yielded 10,000 optimal equipment assignments. We clustered using the k-means algorithm. As a result, the two clusters of Yeosu, Daesan, and Ulsan, which are expected to be the largest spills, were clearly identified. We also projected 16-dimensional data in two dimensions via Sammon's mapping. The projected data were analyzed for distribution. We confirmed that results of the simulation were better than those of optimal equipment assignments included in the cluster.In the future, it will be possible to implement an approximate model with excellent performance based on this study.
