Internal corrosion in normally dry gas pipelines can remain hidden until liquid water accumulates at susceptible locations. Accurately identifying these locations is fundamental to an effective DG-ICDA assessment and proactive pipeline integrity management.

We’re excited to announce the release of DG-Corrology®, a digital solution developed to support DG-ICDA Step 2 – Indirect Inspection.

Built on the DG-ICDA methodology, DG-Corrology® integrates:
* Pipeline inclination profile generation
* Critical inclination angle calculations
* Multiphase flow modelling
* Water accumulation assessment
* Integrated corrosion prediction
* Profile visualization and reporting

Using pipeline operating conditions and elevation profile data, DG-Corrology® identifies locations where liquid water accumulation and internal corrosion are most likely to occur, enabling engineers to prioritize inspections and make more informed integrity decisions.

Key Benefits

* Accelerates DG-ICDA Step 2 indirect inspection assessments
* Supports data-driven inspection planning and prioritization
* Improves consistency and repeatability of engineering assessments
* Provides insight into corrosion susceptibility and system aggressiveness
* Generates engineering-ready results, pipeline profiles, and assessment reports

Whether you’re evaluating existing gas transmission pipelines or planning integrity assessments, DG-Corrology® provides an efficient and practical workflow for identifying potential water accumulation and internal corrosion locations, supporting DG-ICDA Step 2 – Indirect Inspection Assessment.

Interested in learning more or scheduling a demonstration? We’d be pleased to show how DG-Corrology® can support your pipeline integrity program.
