  • Our country has experienced some difficulties with clean up operation of massive marine oil pollution due to the lack of oil spill response equipments. And there was the case that a fishing vessel performed clean up operation had not received any proper payments because of its inefficient oil spill response operation. Thus, it is important to develop an efficient oil recovery equipment for small vessel and adopt it as a part of oil pollution prevention policy. These efforts could prepare oil spill response equipment in advance and use a fishing vessel registered in the affected area by massive marine oil pollution. Therefore, this study examines and adopts a suitable subject vessels as a first step for developing oil recovery system fitting with small vessels for national use.

  • While the amounts of oil spill caused by the VLCC Hebei Spirit indicated 2.5 times more than that of the VLCC Sea Prince, the economic, environmental, and social damages derived from the Hebei Spirit spill were estimated to be about 30 times greater than those from the Sea Prince incident. This study consolidates the appropriate justification for building a multi-purpose large oil spill response vessel to allow swift and efficient handling of catastrophic marine pollution events through an analysis of technical and economic feasibility of such a project. The result of the technical feasibility analysis illustrates that a hopper dredge and oil spill response vessel with a capacity of 4,000 tons should be more appropriate. The result of the economic feasibility analysis indicates that under the most conservative estimates the project appears to be slightly impractical, with a benefit/cost ratio of 0.82, in which self-help efforts, however, can facilitate the project. And medium to optimistic estimates present benefit/cost ratios are estimated to be 2.72 and 5.82 respectively, representing apparent economic feasibility.

  • After the Sewol ferry-sinking incident in 2014, the public interest in safety at sea increased. In order to save and secure the initial response time required for sea rescues, not only the rescue organization, but also the victim needs to save and maintain golden time to secure the necessary time for rescue personnel. The purpose of this study was to investigate ways to maintain the psychological stability of victims during their rescue in the case of a mass rescue operation by using the oil boom installed on board oil spill response vessels. Through buoyancy tests and the development of oil booms in sea areas, it confirmed the buoyancy of two adults weighing 70 kg each per meter of oil boom could be maintained when a lifeline was installed on the side of the oil boom, and that it was possible to keep afloat four persons weighing 70 kg each on both sides of the oil boom. It also confirmed the buoyancy for three adults weighting 70 kg each per eight meters was maintained when riding on the top of the oil boom. As a method of rescue, it was found that the fastest and most accurate way to rescue victims was a rescue boat held at the rear end of the oil boom to lead to victims. In conclusion, the rescue team could utilize the oil boom installed on board the oil spill response vessel located near the marine accident site to save and secure the initial response time required for the rescue team to arrive. The victims in distress holding onto the lifeline or riding on the top of oil boom kept afloat at sea could maintain their psychological stability until the mass rescue operation initiated.

  • On April 20, 2010, semi-submersible offshore drilling unit Deepwater Horizon was exploded and sank, and 4.9 million barrels(about 778 thousand tons) of crude oil was spilled into the Gulf of Mexico. As more than one year has been passed since the incident, a lot of investigation reports and lessons learned have been made public and also a lot more will be released soon. This paper studies the final report of the National Commission on "the BP Deepwater Horizon Oil Spill and Offshore Drilling", which was organized by the executive directive of U.S. President Barack Obama, and the interim report of Joint Investigation team of U.S. Coast Guard and BOEMRE of "Report of Investigation into the Circumstances Surrounding the Explosion, Fire, Sinking and Loss of Eleven Members Aboard the Mobile Offshore Drilling Unit Deepwater Horizon". The review is focused on the response to the oil spill. And the paper suggests how to improve national marine pollution response policy. In the paper, the Korean governments is suggested to reinforce the capability for instructing and supervising the responsible party's source control measures, to review how to introduce in-situ burning and vessel of opportunity program into our country, and to continue monitoring on the progress of developments of R&D projects related to oil spill response in the U.S..

  • 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.

  • Hebei Spirit Oil Spill that happened in 2007 had prompted the need of revisiting the coastal safety. In response to this, Korea had made an effort to implement VTS in every coastline in the country. There are a lot of theoretical studies on VTS function nowadays, but coastal VTS are less frequently studied. In this paper, performance analysis results and accident prevention activities of Jindo Coastal VTS center were summarized and the Coastal VTS function are investigated. Jindo Coastal VTS covers relatively wide area and various places with various maritime traffic characteristics are the major navigation vessels, which means that it is important to control these vessels. Since the probability of accidents due to human error is relatively high in coastal area due to negligence tendency of crews during coastal area navigation, coastal VTS has to provide sufficient assistance to navigating vessels. Like most harbour VTS, Coastal VTS provides not only main information service, navigational assistance and traffic organization services but also various services related with advanced search-and-rescue assistance, marine national security, maritime crime prevention, oil spill response, traffic services for non-service vessel, and safety supervision for water leisure boats.
