Semi-Probabilistic Evaluation of System Redundancy for Existing Offshore Structures

Zhang Shengkun Chen Kaisheng Mu Yang Professor, Department of Naval Architecture and Ocean Engineering, Shanghai Jiao Tong University Shanghai 200030 Lecturer, Department of Naval Architecture and Ocean Engineering, Shanghai Jiao Tong University Shanghai 200030 Assistant, Department of Naval Architecture and Ocean Engineering, Shanghai Jiao Tong University Shanghai 200030  
In this paper, a new definition of structure system redundancy is proposed in view of the various measures for structure redundancy. By introducing the terms of structure system failure at the mechanism level and equivalent reliability index, the safety for existing offshore platforms can be evaluated by the semi-probabilistic method presented in this paper. Some numerical examples are given and satisfactory results have been obtained.
