RISReliability Evaluation of Corroding Pipelines Considering Multiple Failure Modes and Time-Dependent Internal Pressure
Publisher: American Society of Civil Engineers
Abstract: A methodology is developed to evaluate the annual failure probabilities of a pressurized pipeline at an active metal-loss corrosion defect. The methodology takes into account three different failure modes at the defect ...
An Efficient Methodology for the Reliability Analysis of Corroding Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an efficient methodology that utilizes the first order reliability method (FORM) and system reliability approaches to evaluate the timedependent failure probabilities of a pressurized pipeline at a ...
Impact of Model Errors of Burst Capacity Models on the Reliability Evaluation of Corroding Pipelines
Publisher: American Society of Civil Engineers
Abstract: This paper quantifies the impact of model error associated with the burst capacity model on the probability of burst of corroding oil and gas pipelines due to the internal pressure. Three burst pressure models that are ...

Development of Probability of Ignition Model for Ruptures of Onshore Natural Gas Transmission Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A loglogistic probability of ignition (POI) model for ruptures of onshore natural gas transmission pipelines is proposed in this paper. The parameters of the proposed POI model are evaluated based on a total of 188 rupture ...
A Burst Capacity Model for Corroded Pipelines Subjected to Combined Internal Pressure and Longitudinal Compression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study proposes a new semi-empirical burst capacity model for corroded oil and gas pipelines under combined internal pressure and longitudinal compression. The proposed model evaluates the burst capacity of a ...
Interaction Assessment of Diagonally Spaced Identical Corrosion Defects and Fully Aligned Unequal-Sized Corrosion Defects Under Combined Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the interaction effects of closely spaced corrosion defects on the burst capacity of oil and gas pipelines under combined internal pressure and longitudinal compression are investigated by using parametric ...
Optimal Design of Onshore Natural Gas Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The optimal design level for onshore natural gas pipelines was explored through a hypothetical example, whereby the pipe wall thickness was assumed to be the sole design parameter. The probability ...
Alternative Load Paths in Steel through-Truss Bridges: Case Study
Publisher: American Society of Civil Engineers
Abstract: Conventional design and evaluation procedures usually classify steel through-truss bridges as single-load-path structures; however, their historic performance has demonstrated considerable structural resiliency. This paper ...
