국내 주요항만에서의 선박평형수 배출량 추정

Abstract

범지구적 해양환경을 보존하기 위한 일환으로, 국제해사기구에서는 선박의 평형수관리에 대한 협약을 2004년도에 채택하였다. 해양시스템안전연구소에서는 이에 대한 기초적인 연구를 수행하고 있다. 그 중 하나로, 2006년도에 우리나라 주요항구를 출입한 국제항행선박을 대상으로 밸러스트 작업에 의한 항만내에 선박평형수 흡입량 및 배출량 추정기법을 개발하고, 그 양들을 추정하였다. The International Convention for the Control and Management of Ships Ballast Water & Sediments was adopted by consensus at a diplomatic conference of IMO at 2004. MOERI has been developing various fundamental technologies such as biological survey, type approval procedure and technical information for formulation of the regulation for national strategy of the IMO Convention. MOERI also started to develop the risk assessment technology of ballast water. For the risk assessment, sampling survey of ballast water discharge has also been conducted because it was not mandatory procedure to submit the ballast water reporting form to port states and there were no any statistics for ballast water discharge in Korea. The information items of voyage and discharge of ship's ballast water are derived. Using the 97 results by sampling survey on the relation between loading/unloading and discharge/uptake of ballast water, the amounts of discharge/uptake of ballast water at each port and all of country in Korea are predicted. The uptake of ballast water is predicted to about 70 million ton in Korean important ports at 2006 which is over 3 times than discharges.
