Abstract
Presented on Wednesday 17 May: Session 18
The ability to store large volumes of carbon dioxide (CO2) is becoming critical to the success of resource projects and sustainable industrial development, particularly in the context of net zero emissions (NZE) goals. Converting ageing hydrocarbon facilities for use as part of an overall carbon capture and storage (CCS) system can be a very cost-effective strategy. However, there are many significant challenges which need to be addressed to assure CCS system safety, functionality, operability and integrity. This paper summarises the key elements of the repurposing process for conversion of ageing offshore hydrocarbon production facilities and associated pipeline infrastructure for use in CCS systems, highlighting key challenges and solutions. The repurposing elements addressed are facility development for CO2 service, facility life extension, operational conversion and Safety Case development. Key challenges identified include development of design and operating philosophies, safety management including loss of containment characterisation and pipeline requalification. The paper is based on experience in assessing the suitability of offshore gas production facilities for high-volume CO2 injection.
