Full title and description

ISO 27913:2024 — Carbon dioxide capture, transportation and geological storage — Pipeline transportation systems. Guidance and requirements for design, construction, operation, conversion and monitoring of rigid metallic pipeline systems used to transport CO₂ streams (gaseous and dense phases) from capture sites to geological storage or other uses.

Abstract

This International Standard specifies requirements and recommendations for the safe and effective pipeline transportation of CO₂ streams. It covers onshore and offshore rigid metallic pipelines and pipeline systems, including conversion of existing pipelines for CO₂ service, stream quality considerations, flow assurance, integrity management, health, safety and environmental aspects, and monitoring/measurement for transportation to geological storage or other uses. Transportation by ship, rail or road is excluded.

Scope

Applies to pipeline transportation of CO₂ streams from capture sites to storage facilities or other uses (e.g., CO₂-EOR). It covers rigid metallic pipelines and pipeline systems, onshore and offshore routes, conversion of existing pipelines to CO₂ service, and transport of CO₂ in gaseous and dense phases. The standard addresses CO₂ stream quality assurance, converging streams from multiple sources, flow assurance and monitoring, and HSE aspects specific to CO₂ transport. It does not cover transport by ship, rail or road.

Key topics and requirements

• Pipeline materials selection, design and construction suitable for CO₂ service (including considerations for dense-phase CO₂, impurities and phase behaviour).
• Requirements for conversion of existing pipelines to CO₂ transport (assessment, remediation and qualification).
• Flow assurance: handling phase changes, hydrate formation, corrosion and erosion risks, and mitigation measures.
• CO₂ stream quality management and specifications to limit deleterious impurities and protect system integrity.
• Operational requirements: compression, dehydration, pigging, metering and custody/flow measurement.
• Integrity management, inspection, testing, maintenance and fitness-for-service principles adapted to CO₂.
• Health, safety and environmental (HSE) measures, emergency preparedness and leak detection/monitoring.
• Monitoring, instrumentation and data needed for safe transport and for verification in storage-chain projects.
• Requirements for documentation, risk assessment and regulatory/compliance interfaces.

Typical use and users

Used by CCS project developers, pipeline designers and engineers, operators and owners of CO₂ transmission systems, EPC contractors, technical consultants, regulatory agencies and permitting authorities, asset managers performing integrity assessments, and organizations involved in measurement, monitoring and verification of CO₂ transport and storage chains.
