Cathodic disbonding at elevated temperatures has not been thoroughly studied. As offshore
oil and gas production moves towards higher temperatures there is a need for a better understanding of
coating degradation, products with higher temperature limits and probably also new guidelines for
design of cathodic protection. Standard test methods for high temperature cathodic disbonding are
available, primarily for pipeline coatings. However, these methods may not be applicable for offshore
structural coatings. The objective with this work is to design a test method that simulates the exposure
conditions for coatings on submerged high temperature constructions. Cathodic disbonding is normally
considered to be the main degradation mechanism for submerged coatings, but as temperature increases
other degradation mechanisms may actually become more important, e.g. thermal degradation of the
binder. Hence, how the high temperature affects e.g. film and barrier properties will also an important
part of this work.
