Probabilistic modelling of free spanning pipelines considering multiple failure modes
MM Shabani, H Shabani, N Goudarzi… - Engineering failure …, 2019 - Elsevier
Free Spanning occurs due to unevenness of seabed, artificial supports and etc. Based on
DNV-OS-F101, free spanning may cause Vortex-Induced Vibration (VIV), local buckling and
pipeline bursting. The purpose of this study is to present a methodology for assessing free
spanning pipelines in terms of Probability of Failure (POF). In order to assess VIV fatigue of
subsea pipelines, a Finite-Element Reliability based method with aim of Artificial Neural
Network (ANN) is proposed. For training ANN, 560 different ABAQUS FE scenarios with …
