Digital Twin as a Tool for Extending In-Line Inspection Intervals

Aging pipeline assets are a concern for many pipeline operators. As pipelines age, external corrosion control becomes more challenging and often results in more aggressive monitoring and maintenance activities such as more frequent in-line inspections (ILI) and direct examinations. A pipeline case study is discussed demonstrating how a digital twin based on mechanistic modeling was utilized as a proof of concept for identifying possible cathodic protection remedial actions to decrease external corrosion growth rates (CGR) with the goal of extending the ILI inspection interval from 3 to 5 years. Various remediations such as adjusting or adding cathodic protection and resolving interference are modeled and compared with the existing corrosion control configuration. An economic analysis is included to determine if theoretical remediations can reduce monitoring and maintenance costs while maintaining asset integrity.

Top of Line Corrosion in Multiphase Gas Line Operational Feedbacks

The first case of top of line corrosion (TLC) in Tunu gas field was reported by Gunaltun et al in 19991. Inline
inspection (ILI) of two carbon steel pipelines distributing multiphase effluent, showed up to 50% metal
loss at 11.00 – 01.00 o’clock at several sections. Visual examination of a cut section showed that the top
of line was covered with iron carbonate layer with deep pits, and severe metal loss occurred on large
surfaces at these area.
