The transition to a low-carbon economy necessitates rapid deployment of CO₂ transport infrastructure. This study presents a techno-economical feasibility assessment for repurposing legacy oil pipeline for CO₂ transport. The assessment is grounded in DNV-RP-F104 and incorporates lessons learned from international CCS projects and ongoing DNV JIPs. Existing pipeline, originally designed for oil has been evaluated for its suitability to transport CO₂ over a distance exceeding 100 km. The study includes a preliminary integrity screening, fracture control assessment, and hydraulic evaluation to determine compatibility with CO₂ service conditions, including pressure, temperature, and impurity thresholds.

A multidisciplinary methodology integrates technical, regulatory, and economic dimensions. Key components include:
• Material compatibility and corrosion risk assessment under CO₂ exposure
• Hydraulic modeling to assess phase behavior and transport capacity
• Safety and dispersion analysis for CO₂ release scenarios
• Regulatory and permitting landscape review aligned with EU and local frameworks.
• Risk identification

The study concludes that with targeted modifications and implementation of CO₂-specific integrity management protocols repurposing is technically feasible. This work provides a framework for infrastructure reuse in support of CCS deployment across Europe.
