Controlling AC Safety And Corrosion Risks on Pipelines with Digital Twins

Product Number: MECC23-20075-SG

Author: Christophe Baete

Publication Date: 2023

$20.00

According NACE21414 and ISO18086 standards AC corrosion risks on pipelines requires knowledge on the AC and CP current density on a coating defect or coupon. The induced voltage is mainly a result of the pipeline coating properties, connections to grounded structures (anode beds, other pipelines, AC grounding systems, etc.) and the powerline characteristics (AC load, phase arrangement, tower configuration, etc.). A proper mitigation design engineering study should include all these variables.

Estimating Corrosion Rate Risk Distributions using Machine Learning and Geospatial Analytics

Product Number: 51320-14640-SG

Publication Date: 2020

Estimating corrosion growth rates for underground pipelines is a challenging problem. There are confounding variables with complex interaction effects that may result in unexpected outcomes. For instance, the relationship between soil conditions and AC interference is highly non-linear and challenging to model. This work expands upon prior work using a suite of machine learning tools to estimate corrosion rates. However, instead of estimating a single corrosion growth rate for a single girth weld address (GWA), this work estimates a distribution of potential corrosion growth rates. Modeling distributions provide a more effective risk-measurement framework, especially concerning high volatility or areas of severe tail risk.

This work relies heavily on machine learning and geospatial tools - particularly artificial neural networks and gradient boosted trees to estimate the corrosion rates and non-linear processes. Building upon prior work using data from a North American Operator, the models in this paper use additional variables from recent research in AC interference and microbiologically influenced corrosion to construct a higher accuracy and distribution-based model of pipeline corrosion risk.

On-Site Parameter Measurements And Corrosion Coupon Tests Of Buried Pipeline Subject To AC Interferences Of High Speed Railway

Product Number: 51322-17725-SG

Author: Le Chen, Jianjun Li, Yanxia Du, Nianpei Tian, Jia Liu, Yi Liang

Publication Date: 2022

$20.00

With the rapid development of the economy and acceleration of urban modernization, many high-speed railways and buried pipelines have been built in China. Due to the limitation of space or geographical location, high-speed railways are often constructed in parallel or crossing with long-distance pipelines in some locations. The interference of high-speed railways on pipelines is the result of inductive and conductive coupling, which brings about AC corrosion and other safety issues.
