Journal ArticleDOI
Corrosion induced failure analysis of subsea pipelines
TL;DR: An approach to analyze the observed abnormal events to assess the condition of subsea pipelines by establishing a systematic corrosion failure model by Bow-Tie analysis, and subsequently the BT model is mapped into a Bayesian Network (BN) model.
Journal ArticleDOI
Risk assessment of offshore crude oil pipeline failure
TL;DR: In this paper, an integrated risk-based assessment scheme is presented to predict the failure and the failure consequences of offshore crude oil pipelines, and the outcome of the assessment facilitates an informed decision-making about the future of the asset.
Journal ArticleDOI
Risk based integrity modeling of offshore process components suffering stochastic degradation
TL;DR: In this article, a risk-based integrity model for the optimal replacement of offshore process components, based on the likelihood and consequence of failure arising from time-dependent degradation mechanisms, is developed.
Journal ArticleDOI
The selection of corrosion prior distributions for risk based integrity modeling
TL;DR: This paper presents a methodology to select the prior distributions for the various types of corrosion degradation mechanisms, namely, the uniform, localized and erosion corrosion, and finds that uniform corrosion can be best described using 3P-Weibull and3P-Lognormal distributions.
Journal ArticleDOI
Revised burst model for pipeline integrity assessment
TL;DR: In this article, the authors analyzed the changing trend of burst pressure of pipelines with different defect dimensions and compared the FEM results with those of the evaluated criteria (DNV model) to indicate the conservative property.
