The paper will cover the construction method (based on Random forest algorithms), the first results. We will see the enhancements of the model by injecting more data and modifying mathematical rule, and how it will be able to integrate a new decision support tool.

We can now make improvements on the assessment of the external coating condition of underground pipelines: in fact, after excavation and examination, only a small proportion of detected coating anomalies contain also a metallic fault or worse corrosion. GRTgaz, operator and owner of the longest high-pressure natural gas grid in Europe (approximatively 32 000km (19,884 miles), has tested an analytical approach based on historical data to increase the success rate (from the understanding of the problem and the available data, to the elaboration of algorithms and the optimization of their parameter). Different data sources to extract new knowledge have been used, works have been prioritized and the excavations have been optimized in order to have fewer but more efficient interventions.

CP Shielding and Pipeline Coatings

Product Number: 41206-285-SG
Author: Greg Ruschau
Publication Date: 2006
$20.00

Shielding of cathodic protection (CP) by pipeline coatings poses a serious threat to pipeline integrity.  The difficulty in pipeline coating selection to avoid shielding is that the same properties that make a pipeline coating a good corrosion mitigation material can also lead to CP shielding. The key to proper coating selection is to select a coating that has the necessary properties to provide good corrosion protection but also one that, when disbondment and failure occurs, fails in such a way to allow effective cathodic protection.

Decision Making Under Uncertain Erosion Conditions Using The Probabilistic Model

Product Number: 51322-17813-SG
Author: Guanlan Liu, Francois Ayello, Jose Vera, Richard Eckert
Publication Date: 2022

Erosion is one of the major threats of the pipeline integrity1 when it’s transporting liquid hydrocarbon products with solid particles. The erosion process decreases the effective wall thickness and therefore reduces the capacity of the pipeline to contain the pressured product. This can induce serious consequences including property, health and safety, environment, and business costs.
