Abstract
Jinhae bay, which is located at southeastern part of korean peninsula, is one of the sensitive waters as many kinds of marine lives are farming. In this area, environ -mental problems such as red tide have risen every year probably due to slow exchange of waters, industrial waste from factories and housekeeping along the coast and so on. In addition, it is recently expected that there exists potential oil spill disaster by ship's accident in the future as a number of vessels move in and out of the harbors of Masan and Jinhae.


In this regards, the author investigated and analyzed meteorological and hydrographic data, marine traffic data, shoreline features and stockpiles of response equipments, and finally evaluated the capabilities of marine oil spill response with the establishment of possible spill scenario.


The results of the study are as follows.


(1) In Jinhae bay, meteorological and hydrographic conditions show no unfavorable to spill response with relative weak wind and tidal current.


(2) Shorelines consist of rocky flat, man-made solid shore, beach shore and tidal flat, there are not many sensitive areas within this area. For this shore, natural recovery, low-pressure cold and warm water washing, high-pressure cold and warm water washing, manual removal, removal by sorbent and mechanical removal can be used as shoreline clean-up.


(3) Under the scenario of worst case of spill accident which can most probably takes place around pilot boarding ground north of Gadeokdo Island, numerical simulation was done to find the movement and spreading of oil slick. It is found that oil slicks move and spread southward in winter with 3.0 m/s N'ly wind & 13℃ SST and oil slick move & spread northeastward in summer with 3.0m/s SE'ly wind & 25℃ SST.


(4) With consideration of the movement characteristic of oil slick, it is computed that stockpile of boom of 7,700m in winter and 11,300m in summer and skimmers of 657.5m·ton/hour recovery rate should be kept with additional appropriate amount of synthetic organic sorbent but the use of chemical dispersant is strongly prohibited in this area.
