As potential of oil spill accident in Busan area is growing with an increase of trade and marine traffic, it become important to provide a realistic and practical response plan to address spilled oil effectively. The authors make a most probable scenario of spill accident to investigate an seasonal applicable response techniques. As a result, it is found that mechanical recovery and/or shoreline clean-up operation are required at the eastern shore of Taejongdae in spring and autumn. In summer, since spilled oil moves and contaminates a lot of sensitive areas in Suyeong Bay, a prompt action is required to mechanically contain and recover as much oil at sea surface as possible, at the same time shoreline counter-measures are commenced. In winter with off-shore wind, no action will be required because there is no risk of oil migration to shore. In addition to mechanical recovery and shoreline clean-up, the use of concentrate dispersant can be an primary option especially in spring and autumn as there is less possibilities to contaminate sensitive areas and sufficient deep waters. However, special care is taken to select response options according to the weather condition at the time of spill.
