The Influence of the Brace Topology on the Reliability of the Platform Jacket Structure

Abstract:

Platform jacket structures are offshore buildings that support oil and gas drilling activities. The jacket's structure is generally tubular steel connected between the legs and the brace. The selection of brace topology is essential to prevent the structure from failure, such as fractures. The research was carried out by modelling the brace topology and analyzed using SACS finite element method software. Analysis of the reliability of jacket structure using the Monte Carlo simulation method. The purpose of this study is to analyze the reliability of the jacket structure and determine the optimal topological clamp model for use on it. The results show that the topology X brace model has better reliability than the support topology model K and N, where the topology X brace model can withstand a maximum force of 44000 kN with a reliability index value of 3.35. In comparison, the topology K brace can withstand a working force of 35200 kN with a reliability index value of 2.94, and the topology N brace model can withstand a working force of 32000 kN with a value of reliability index of 3.02.
