Overview
ISO 27913:2024 - Carbon dioxide capture, transportation and geological storage - Pipeline transportation systems defines requirements and recommendations for transporting CO2 streams by rigid metallic pipelines and pipeline systems (onshore and offshore). The standard covers gaseous and dense-phase CO2, conversion of existing pipelines, CO2 stream quality assurance, converging streams from multiple sources, and health, safety and environmental aspects specific to CO2 transport. Transportation by ship, rail or road is excluded.
Key topics and technical requirements
ISO 27913:2024 addresses technical and operational topics critical to safe, reliable CO2 pipeline transportation:
- Properties of CO2 and stream behaviour
- Thermodynamic and phase behaviour of pure CO2 and mixed CO2 streams
- Chemical reactions, hydrate risk and corrosion mechanisms
- System concept and design criteria
- Safety philosophy, reliability and availability targets
- Pressure control, protection systems and short-term storage reserves
- Flow assurance for single-phase and transient multi‑phase operation
- Materials and pipeline engineering
- Steel selection, external coatings and suitability of non‑metallic materials
- Measures to avoid internal corrosion and manage water content
- Structural design
- Wall thickness calculation principles, fracture toughness considerations and dynamic loading
- Construction and pre-commissioning
- Dewatering, drying, preservation and initial filling/pressurization procedures
- Operation, inspection and monitoring
- Commissioning, shutdown, depressurization, vent facility design
- In-line inspection, leak detection, water content monitoring and custody transfer measurement
- Health, safety and environment
- HSE risk controls, fugitive emissions, venting design and emergency response
- Integration aspects
- Converging CO2 streams, conversion of existing pipelines and interfaces with storage or use (e.g., EOR)
Practical applications
ISO 27913:2024 is a practical reference for projects that design, build, operate or regulate CO2 pipeline systems in carbon capture and storage (CCS) programs. Typical uses include:
- Designing onshore/offshore CO2 transmission pipelines and compressor/pump station layouts
- Evaluating conversion of natural gas or oil pipelines for dense‑phase CO2 transport
- Implementing CO2 stream quality assurance and custody transfer measurement
- Developing operational procedures, inspection regimes and HSE risk controls
- Supporting permit applications, safety cases and stakeholder engagement for CCS projects
Who should use this standard
- Pipeline designers and engineers
- CCS project developers and operators
- Safety, environment and integrity management professionals
- Material and coating suppliers, inspection and testing firms
- Regulators, insurers and consultants involved in CO2 transport and geological storage
Related standards (if applicable)
ISO 27913:2024 complements other international and national standards for carbon capture and storage, pipeline engineering, material testing, and health & safety management. Users should align ISO 27913 guidance with applicable pipeline design codes, environmental regulations and local permitting requirements.
