Evaluation of surface crack damage on semi-submersible platform

Li Jie~(1,2) Duan Menglan~2 Zhou Songmin~3 Zhang Wen~1(1.Department of Mechanics and Engineering,Fudan University,Shanghai 200433,China;2.China Classification Society,Beijing 100006,China;3.Oilfield Service Company Limited,CNOOC,Zhanjiang 524057,China)  
The global structure analysis and local crack evaluation on the semi-submersible platform servicing in South China Sea were carried out by finite element method and fracture mechanics theory.The fracturing parameters for describing the cracks and their propagation on the local shell plate of the platform were determined.The effects of local shell plate corrosion factor on the fracturing parameters distributed around the crack tip were investigated using ABAQUS software.The global structural strength evaluation to obtain the necessary boundary conditions for the analysis of local fracture was made.The distribution of stress intensity factor along crack front was analyzed by the fracture mechanics.
