About this Training Course
As carbon capture, utilisation and storage projects move from concept into implementation, CO₂ transportation systems are becoming a critical part of the energy transition. Pipeline operators, project developers and engineering teams must understand how CO₂ service differs from conventional oil and gas transportation, particularly in relation to dense phase behaviour, impurities, corrosion, fracture control, inspection, operations and long-term integrity management.
This course provides a practical technical overview of CO₂ pipeline integrity management, with emphasis on the engineering, corrosion, materials, operations and risk-based integrity issues that affect CO₂ pipeline systems. The course is designed to support engineers and technical professionals involved in the development, assessment, operation or management of CO₂ transport infrastructure.
The programme is suitable for both new-build CO₂ pipelines and the repurposing of existing oil and gas infrastructure. Particular attention is given to long-distance transportation, shipping-linked CO₂ networks, regional demand centres and the practical challenges associated with multi-source CO₂ streams.
Q1: What is CO2 Pipeline Integrity Management?
CO2 Pipeline Integrity Management is a clear process that helps teams keep CO2 pipelines safe, reliable, and compliant. It helps teams find threats, check risks, track damage, and plan inspections. In addition, it supports repair plans, corrosion control, fracture control, and safe operating limits. As a result, it helps reduce leaks, failures, downtime, and harm to the environment.
Q2: Why does CO2 pipeline integrity need special management?
CO2 pipelines behave differently from oil and gas pipelines. For example, they often carry dense-phase or supercritical CO2, which can change phase during pressure drops. As a result, the pipeline may face higher fracture risk. Also, water and impurities can create corrosive conditions. Therefore, teams need special design, monitoring, and repair plans.
Q3: What are the main threats to CO2 pipeline integrity?
The main threats include internal corrosion, external corrosion, fracture growth, mechanical damage, material flaws, ground movement, and operating upsets. In addition, CO2 pipelines can face added risks from water, impurities, and rapid pressure loss. Therefore, teams manage these threats with inspections, risk checks, operating controls, and planned maintenance.
Q4: Why is corrosion control important in CO2 Pipeline Integrity Management?
Corrosion control is a key part of CO2 Pipeline Integrity Management because CO2 can form carbonic acid when water is present. Also, oxygen, sulfur compounds, and nitrogen oxides can make corrosion worse. Therefore, teams reduce this risk by controlling water, limiting impurities, choosing the right materials, using inhibitors, and inspecting pipelines often.
Q5: How do operators assess risk in CO2 pipeline systems?
Operators assess risk by finding threats, judging failure likelihood, and checking possible impacts. Then, they rank the risks and choose the best actions. For example, they may use failure mode studies, corrosion models, fracture models, and impact models. As a result, teams can plan inspections, repairs, and emergency response more effectively.
Q6: What inspection methods are used for CO2 pipelines?
Teams use in-line inspection tools, ultrasonic testing, magnetic flux leakage, radiography, pressure testing, corrosion sensors, and external surveys. However, the best method depends on pipe material, operating conditions, impurity levels, and likely damage types. Therefore, good inspection planning helps teams find problems before they lead to failure.
Q7: What standards apply to CO2 pipeline integrity management?
CO2 pipeline integrity programs usually follow international standards, national rules, and industry guidance. For example, teams may use ISO standards, ASME codes, DNV practices, and local pipeline safety rules. Together, these sources guide design, materials, fracture control, inspection, risk management, and safe operation.
