Integrity Management of Carbon Dioxide Pipelines
Abstract
Existing defect methodologies are aligned with the management procedures and are adopted to inspect, assess and repair the pipelines for defects and take suitable measures to reduce them. However, the applicability of these techniques in the presence of gaseous phase Carbon Dioxide remains uncertain. The project will identify relevant defect types which may be encountered and considered hazardous in the presence of carbon dioxide, study the impact of gaseous phase carbon dioxide and corrosion has on them, assess whether the failure mechanism has changed after introducing carbon dioxide and recommend inspection, assessment, and repair approaches. Additionally, the project will capture the extent of repairs across the NTS and assess the impact of implementation of the recommended gaseous phase carbon dioxide inspection, assessment and mitigation technologies in terms of safety and useability.
