Session 27. Oral Presentation for: Mapping of the regulatory requirements for requalification of hydrocarbon production pipeline facilities for CO2 transport and storage

Presented on 29 May 2025: Session 27 The prevalence of global hydrocarbon production facilities creates enormous potential for equipment repurposing and life extension through conversion into carbon transport and storage facilities. This could extend the serviceable life of existing assets nearing the end of their production cycle, with the possibility of reducing the burden of new capital infrastructure for CO2 transport and storage through the repurposing of existing infrastructure. The paper highlights the key regulatory approvals for the requalification of offshore hydrocarbon production pipeline infrastructure for use with CO2 transport and permanent storage. It identifies the requirements of DNV-RP-F104 and AS 2885, as they relate to an Australian regulatory context. The paper describes a structured approach towards the requalification of a pipeline system for change of service to CO2, including the timing of requalification actions such as technical studies and mechanical tests. Specifically, it discusses the technical challenges for ensuring safety, material suitability, and component qualification for CO2, as well as identifying requisite new infrastructure and the potential challenges of modifications and repairs, pre-commissioning, first fill and injection processes.
