API RP 1192:2025

This standard focuses on the design, construction, operation, maintenance, integrity management, and emergency response for both dense-phase (including liquid and supercritical state) and gas-phase carbon dioxide (CO2) related to pipelines and related appurtenances and facilities.

The provisions are applicable to onshore gathering and transmission pipelines and related facilities used to convey CO2 in gas- and dense-phase conditions. Offshore pipelines and sequestration facilities were considered in the development of this document to support these applications.

Carbon capture and sequestration involves collection, transportation, and storage of CO2; however, this document does not specifically address processes and procedures associated with capture, injection, utilization, or storage.
