Take Note
This article explains how to creating and running a new CO2 corrosion assessment using the Full Hydrocor module for a Pipeline in the IMS system:
Open the Pipeline’s “HC10_Case01_02_03_CO2_corrosion” Equipment Details Page.
Open the Internal Corrosion Module.
In the Hydrocor section, click the + button to create a new Assessment.
Enter the Date as “01/Jun/2025”.
Enter the assessment Name as “Case 1 CO2 corrosion”.
Click Save.
Click the Hydrocor icon to open the Hydrocor Application.
Select the 1 Settings tab.
Under Degradation Mechanisms select the “CO2” checkbox.
If you are running Hydrocor inside IMS PLLS the Service Type, Pipeline Diameter, and Length fields are automatically populated using information from the Pipeline Design Data.
To modify the Service Type, Pipeline Diameter, or Length, return to the Pipeline’s Equipment Details page PL Design Data section.
Click Edit and update the parameters as follows::
Pipeline Length: 1000m
Nominal Diameter: 12”
Service Type: Multiphase gas/condensate
Click Save.
Click the Internal Corrosion icon, then select the Hydrocor icon to return to the Hydrocor Application.
Select the 2 Main Input tab and specify the following parameters:
CO2 content gas = 2 mole%
Pressure inlet = 120 bara
Temperature inlet = 60°C
Ambient temperature = 7°C
Gas flow rate = 0.5 mln Sm3/d
Oil/Condensate flow rate = 200 m3/d
Water flowrate = 150 m3/d
Click the Run and Save button to execute the corrosion prediction case.
Review outputs including corrosion rates, material recommendations, and visualization profiles.
