Abstract

In this article, a generic engineering critically assessment is discussed and the specific requirements for CO2 pipelines, transporting captured impure CO2 are highlighted. The failure assessment diagram methodology is proposed in the engineering critically assessment in order to incorporate the dominant failure modes, i.e. brittle and ductile failure, and assess the safety and acceptability of the assets. In this article, the likely damage mechanisms are identified, among which are corrosion, stress corrosion cracking, cleavage, ductile failure and the effect of general ageing. All of these mechanisms and contributing factors to the damage of CO2 pipelines are integrated through a novel engineering critically assessment. Areas where these mechanisms for captured CO2 pipelines differ from natural gas pipelines are elucidated and relevant recommendations as to the safe application of these models are made.
