A Study on the Economic Analy sis for Ballast Water Treatment System

AbstractVarious kinds of ballast water treatment systems (BWTS) have been developed corresponding to reinforced IMO rules for marine environment. Some of them got the certificate of IMO and others are waiting for it. Selection of optimum BWTS is very important. Optimum BWTS means not only functional requirements but also economic efficiency. This paper presents economic analysis model for opt imum BWTS according to ship type and size. In this study 10 kinds of BWTS whose initial installation cost and maintenance cost are known are analyzed based on present worth method. It is assumed that all BWTS satisfy minimum functional requirements and we ne ed to consider different economical efficiency. Through the economic analysis we could s elect optimum BWTS. ※Keywords: Ballast water treatment system(밸러스트 수 처리 장치), Initial installation cost(초기 설치비용), Maintenance cost(운영유지비), Present worth method(현재가치법) 접수일: 2009년 1월 19일, 승인일: 2010년 3월 5일✝교신저자: scshin@pusan.ac.kr, 051-510-2525 1. 서 론 IMO에서 채택된 “선박의 밸러스트수와 침전물의 통제 및 관리를 위한 국제협약”(IMO 2004)에 대비하여 많은 기업들과 처리기술들이 IMO의 기
