DEVELOPMENT OF AN UNCERTAINITY INSENSITIVE HEALTH MONITORING METHOD FOR OFFSHORE JACKET PLATFORM USING MODEL UPDATING AND FUZZY LOGIC SYSTEM

Steel jacket-type platforms are by far the most common kind of offshore structures. The main criterion in the maintenance of these structures, as any other structures, is ensuring of thestructural safely performances during their design service life [1]. This research is an experimental investigation on a laboratory model of a jacket platform for developing a robust damage detection technique which is less sensitive to both measurement and analytical modeluncertainties. Fuzzy logic system (FLS) and probabilistic analysis is developed for global damage detection and Linguistic classification of damage
