Abstract

Jacket offshore platform structure are the big space structures usually used in field of offshore oil engineering. Local damage of platform may occur in the action of emergency, and will result in the whole failure of platform under extreme loads. So it is necessary to analyze the failure mode and damage control method for the jacket platform. We first studied the failure modes of jacket test model under different loads by experiments. Then combined with FEM software ANSYS, the internal force redistribution of jacket structure in the process of failure is analyzed. Further, we studied the damage control methods for jacket upper leg, and analyzed the reinforcement effect.
