Subset Simulation Of Pipeline Corrosion, Crack, And Dents Considering Multiple States With Large-Scale Validation

Paper No. IPC2022-87255

Structural reliability calculates failure probabilities in pipelines to manage risks like corrosion and third-party damage. Traditional Direct Monte Carlo (DMC) simulation is computationally intensive. This paper introduces Subset Simulation, which reduces computational demands by decomposing rare event probabilities. Applied to pipeline failure models, it is validated against DMC, showing improved efficiency and reliability in assessing pipeline integrity.
