Abstract
Presented on Wednesday 22 May: Session 18
Australia has in the order of 3500 km of offshore pipelines currently operating in Commonwealth waters which will require either re-use or decommissioning at the end of hydrocarbon service. Santos are currently developing the Bayu-Undan and Reindeer CCS (carbon, capture and storage) Projects, to make use of the depleted hydrocarbon reservoirs to store carbon dioxide (CO2) via existing offshore infrastructure. A key aspect of these projects is the requalification of existing offshore hydrocarbon pipelines to transport CO2, both of which have been in operation for 10–20 years. The Bayu-Undan and Reindeer pipelines were designed and operated for (a) distinctly different hydrocarbon services and (b) with no initial consideration for future CO2 service. This presents two unique technical starting points in the delivery of safe and robust conversion to CO2 service. Using knowledge gained from this, the paper provides an outline of the key technical considerations to requalification of pipelines unique to the combination of life extension and CO2 service. These are framed in the context of existing industry codes and technical challenges with CO2 pipelines. The outcomes are structured against typical phases in the project lifecycle and opportunities for optimisation of future CO2 re-purposing projects are proposed.
