For the overall safety evaluation of the tension leg platform (TLP) system, the structural strength reliability analysis is essential. The strength reliability of a typical TLP exposed to combined static and extreme wave loads is the subject of this study. A three-dimensional finite element shell model made up of a pontoon, column, and deck that is assumed to be accurate and efficient with tendon system as the boundary conditions was built using a concrete TLP. By employing the proportional loading method based on the design wave method, failure mechanisms for the platform and were determined. The failure mechanisms were then used to derive limit state expressions. The system reliability indexes of the object platform were calculated using the system reliability assessment framework created by the system reliability model suggested in this paper. This work seeks to advance the application of reliability theory in offshore engineering.<\/p>\n\n\n\n
