Abstract

Abstract : A number of offshore platforms operating in the years were built with the outdated criteria. A reassessment analysis of the structures should be conducted for safety and maintenance. Reassessment of a jacket structure subjected to corrosion damages was analysed in this study. Programme SACS was used for modelling and conducting pushover analysis for the jacket structure. There are two types of corrosion damage, 'general corrosion' and 'localised corrosion', and the general corrosion was applied on the structure. Corrosion rates of the jacket structure could be divided into three parts, atmospheric zone, splash zone and full immersion zone. Through the pushover analyses using SACS, the relation between time and RSR/RSR0 was established and it was verified which zone had more corrosion influence to the jacket structure.
