Understanding of Microbiologically Influenced Corrosion in Carbon Steel Pipelines: Towards Developing a Methodology to Assess Probability of Failure

Abstract

This dissertation evaluated critical aspects of microbiologically influenced corrosion (MIC) and generated valuable information for the understanding and management of this corrosion threat. The main outcomes include a better understanding of the preservation requirements for field samples to obtain accurate results; an innovative approach for MIC assessment that consists of the identification of total and active microbial communities; knowledge of the effect that environmental and operational conditions can have on microbial communities and MIC.
