Development of the Automatic Design Program for Scaffolding System of the Membrane LNG Carrier

Abstract Scaffolding system in the membrane LNG carrier is a steel structure composed of various pipe-shaped members connected by specific coupling devices. In this study, the automatic design program for scaffolding system in membrane LNG carrier has been developed. It enables user to arrange members easily considering design constraints and input variables such as size of tank, position of legs, level h eight and so on. In addition to that, it creates finite element analysis model with loading and boundary conditions automatically and carries out structural analysis. With post processor based a state-of-the-art computer graphics, users can easily check the results of structural analysis and make a report for structural safety of scaffolding system. ※Keywords: Membrane LNG carrier(LNG선), Scaffolding system(스카폴딩 시스템), Structural safety(구조 안전성), Structural analysis(구조 해석), Automatic design system(자동 설계 시스템) 접수일: 2009년12월4일, 승인일: 2010년 3월5일 교신저자: hiteace@hhi.co.kr, 052-202-6165
