oa Guidance on Subsea Barrier and Isolation Philosophy for Carbon Capture and Storage (CCS) Systems

IOGP’s Subsea Committee kicked off a new work stream specifically focused on subsea CCS. The primary objective of their work has been to create a new IOGP guidance document for subsea CCS developments. With numerous subsea CCS projects advancing globally, IOGP set an ambitious goal to release the first of the guides by early 2024 – IOGP Report 665 - Design guidance for subsea carbon capture and storage systems. This has been followed up with an addendum IOGP Report 665-1- Subsea Barrier and Isolation Philosophy for CCS Systems that covers barrier and isolation philosophy for CCS systems.

The presentation will start by outlining the objectives behind the new guidance. It will then delve into the structure and content of the document in more detail. Additionally, the audience will be offered several potential ‘use cases’ for the subsea CCS guidance document. It will also discuss the methods adopted highlighting the collaborative efforts of the team of Operators and Suppliers, the challenges they faced, and the innovative design and development solutions adopted.
