Abstract
This paper deals with a methodological approach for external corrosion risk assessment of buried and submerged pipelines based on data achieved through a Cathodic Protection Survey. The main techniques used, for example, CIPP (Close Interval Potential Profile) and TGM (Transversal Gradient Method) are described. Interpretations and analyses of data are illustrated using practical case studies. As well the prioritization of intervention is discussed using a risk matrix approach.
