Probabilistic Neural Network for Reliability Assessment of Oil and Gas Pipelines

Computer-Aided Civil and Infrastructure Engineering, 2002
A fuzzy artificial neural network (ANN)-based approach is proposed for reliability assessment of oil and gas pipelines. The proposed ANN model is trained with field observation data collected using magnetic flux leakage (MFL) tools to characterize the actual condition of aging pipelines vulnerable to metal loss corrosion. The objective of this paper is

Integration of Cfd Analysis and Artificial Neural Networks for Estimation Of Erosion Rate in Oil and Gas Pipelines

Results in Engineering, 2023
Transporting oil and gas via pipelines has been creating countless challenges; sand particles deposit and erode the pipelines wall. Generally, conventional erosion rate prediction models are conservative due to numerous generalizations and theories. Finite Element Analysis via computational fluid dynamics (CFD) approach has proven to be useful to solve
