| Abstract: | According to calculation the probability of failure(Pf) of the Bridge Support I (BS1) jacket, foundation and deck leg structural system for a range of subsidence level is from 7.5 meters to 12.0 meters. The non-linear structure compute model was developed first, and the loads on jacket, deck and bridge were predicted. The system capacity and the reliability for the platform have been calculated finally. According to the analysis results of reliability analysis, the technical measure for platform's life extending have been proposed. The calculation methods and the study achievements can be for reference in similar structure analysis and engineering practice. |
| Keywords: | offshore failure probability reliability reassessment jacket |
