CCS transport Concept Selection Support
Concept selection in CCS presents unique challenges compared to the more mature oil and gas sector, especially when it comes to financing, permitting, and the practicalities of emitter specifications. OI technical background, built on solid experience with CCS projects, positions OI well to advise our clients and help them make the right decisions.

Pipeline Repurposing
Financially derisking CCS projects is paramount for kickoff in many cases. Therefore, asset operators are keen to utilize existing gas or oil pipelines as CO2 carriers because it reduces CAPEX for millions Eur. A thorough repurposing study is required to obtain the necessary permissions and ensure the safety and integrity of the system with this new medium. Quite often, dense CO2 is indeed a difficult medium for pipelines designed for hydrocarbons. Therefore, our experience and trustworthy partners in materials and flow assurance enable us to assess the case from all angles.

CO2 pipeline design
While CO2 pipeline design often follows the well-recognized DNV codes applicable to oil and gas systems (DNV-ST-F101), it’s crucial to account for several intrinsic differences. These arise from CO2’s unique thermodynamic behavior and other fundamental properties, as detailed in the referenced white paper: White Paper Link
