Reliability Analysis of Underground Pipelines Using Subset Simulation
An advanced Monte Carlo simulation method, called Subset Simulation (SS) for the time-dependent reliability prediction for underground pipelines has been presented in this paper. The SS can provide better resolution for low failure probability level with efficient investigating of rare failure events which are commonly encountered in pipeline engineering applications. In SS method, random sampl...
متن کاملTesting of Buried Pipelines Using Guided Waves
Introduction The inspection requirements of pipes that have an operational history of many tens of years have lead to the adoption of new maintenance practices and safety standards. The solution currently considered as best maintenance practice is the direct assessment of 100% of the pipelines with the minimum possible economical impact. The use of RBI (Risk Based Inspection) methods and the in...
متن کاملRELIABILITY–BASED DESIGN OPTIMIZATION OF CONCRETE GRAVITY DAMS USING SUBSET SIMULATION
The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...
متن کاملApplication of subset simulation in reliability estimation of underground pipelines
This paper presents a computational framework for implementing an advanced Monte Carlo simulation method, called Subset Simulation (SS) for time-dependent reliability prediction of underground flexible pipelines. The SS can provide better resolution for low failure probability level of rare failure events which are commonly encountered in pipeline engineering applications. Random samples of sta...
متن کاملDetection of Bending Stresses in Buried Pipelines
When gas or oil pipelines must be laid through sand or permafrost or other unstable soils, the pipe walls can he subjected to large bending loads if the soil shifts. In order to detect this condition and correct it, it would be useful to monitor the state of stress along the pipeline'at regular time intervals using a vehicle that is moved through the line by the fluid or gas in it. The experime...
