  • 유조선의 빈번한 왕래로 발생되는 원유의 누출사고, 무절제한 해안환경 파괴 및 생활하수, 공장폐수의 방류 문제가 최근 대중매체를 통하여 빠짐없이 보도되고 있으며 또 그로 인하여 양식장, 바다낚시, 해수욕장 등 생산 및 생활 환경이 오염되어 일반인들도 직접 간접으로 적지 않게 피해를 입게 되므로 그에 대한 관심이 날로 증가되고 있다. 동해 어항의 경우는 수산물 가공폐수 외에 주변에 주거지 및 상가(횟집) 등이 위치하여 생활오수 등이 다량 발생하고 있다. (중략)

  • The present study was carried out to discuss the suitability of the criterion for the determination of the on-water oil removal resource requirement in Korea by comparison with the US criterion. According to the present criterion in Korea, the on-water response operation against the worst case discharge assuming the oil spillage of 60,000 ton from the accident of DWT 300,000 tanker requires the oil recovery capacity of 19,425 kl/hr (on-water recovery volume 20,000 ton). Under the US criterion, the recovery capacity of 16,667 kl/hr is required to respond to oil spill accident of the worst case discharge from the DWT 300,000 tanker. The result shows that resource requirement from the Korean criterion is 16% higher than US criterion, indicating that thc Korean criterion is reasonable.

  • Sea pollution accidents have been occurred due to the increase of marine ship traffic. Oil spill from the hull hole induced by tanker collision results in the huge sea pollution. Proper and prompt reaction on such oil spill disaster is needed to minimize the damage. Thru-hull emergency wood plug is typically used to manually close small holes, while it is required to develop some mechanical devices for closing large holes in the hull due to huge fluid pressure. Accurate estimation of oil discharge and velocity from such holes are important to develop proper device to control hull hole damage. High resolution CFD modeling investigation on the configurations of hull hole of 7.5 m initial depth and 30 cm diameter, which was observed in the oil spill accident of the Hebei Sprit off the west coast of Korea in 2007, has been carried out to compute the oil spill velocity distribution in terms of flow depth. Friction loss due to the viscous flow and the discharge coefficient of crude oil with specific gravity SG = 0.85 and viscosity of $4-12cP(mPa{\cdot}s)$ at the temperature of $20^{\circ}C-100^{\circ}C$ are presented in terms of Reynolds number based on the results of high-resolution CFD modeling.

  • 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.

  • Port of Busan is Korea's largest trading port processing over 18,000 TEU a year. This rapid growth causes air pollution problems in Busan. Ship emissions are significant air pollution sources and port area is relatively close to the business district, therefore it may have serious effects to the health of local people and environment. In this study, ship emissions are estimated, especially on hotelling large vessels. As a result, Port of Busan has 50,686, 48,842 ship calls and 2,343,037 and 2,297,118 tons of ship emissions in 2011 and 2012 respectively. Also, the environmental cost in Port of Busan is approximately 1.2 trillion won per year. This study emphasizes the necessity of ship emissions regulation, hence, it is expected to make a significant contribution in setting up ship emission management system.

  • The Protocol adopted in Sep. 1997 included the new Annex VI of MARPOL 73/78, which will enter into force on 19 May 2005. MARPOL Annex VI sets limits on sulphur oxide and nitrogen oxide emissions from ship exhausts and prohibits deliberate emissions of volatile organic compound (VOCs) from oil tanker in port and oil terminal. This study was conducted to find out countermeasures for the new Annex VI of MARPOL 73/78 and draw up a feasible management plan. The emission quantity of NOx and SOX from ships in Ulsan Port was calculated by U.S. EPA and Japan Marine Engineering emission factors of air pollutant from ship exhausts. In addition, volatile organic compound (VOCs) from oil tanker during the loading and discharging period, also calculated.
