국제해사기구-해양환경보호위원회 제 46차(외교회의 결정 2001년 10월 5일)회의에서 유기주석계 방오도료 사용금지(2003년 1월 1일 선체 사용금지, 2008년 1월 1일 선체 잔존금지)에 따른 TBT함유 페인트 폐기물의 다량 발생에 대한 처리기술의 개발로 방오 도료 페인트의 최적 처리시스템을 연구하였다. 열분해 반응장치를 이용하여 TBT함유 페인트 폐기물의 열분해 특성 및 처리성능을 평가하였다. TBT함유 페인트 폐기물을 열분해 반응조에서 온도를 1000℃, 반응시간을 1시간 동안 처리했을 때 유기주석이 99% 제거되어 처리효율이 뛰어났다.

Hull roughness due to corrosions of outer hull and had applications on outer hull paints was analyzed theoretically. It's value which was gainable practically, was studied, and estimated power penalty formular correspon-ding to that value were reviewed. Local roughness penalty and roughness texture penalty that paint manahers in ship yard can easily were compared and studied by dotting actual ships in the issued curves. Losses and benifits of hull roughness & the specification choise of A/F paint which managers of ship maintenance were much interested in have been calculated through actual ships. The paper is illustrating that how much the specification choise and managing of A/F paint have effects on fuel consumption of ship in program. It is urgently required that recent developed antifouling paints of new A/F generation should be adopted to new ship building by big shipping companies in view of the environmental protection and the economical maintenance of ships.
