For the last few years, an oil company has carried out laboratory testing of tri-layers PE and PP pipe coatings in hot wet environment.

The objective was to simulate the disbondment from the steel substrate noted in some cases in the field (with no corrosion associated), and understand the physico-chemical mechanism at the origin of the loss of adhesion experienced.

This paper will sum up the results obtained so far from this RD effort, with a special highlight on the following points :

?? Durability of the bond between the steel and the FBE primer/Influence of water diffusion ?? Influence of the FBE type and ageing temperature on the disbondment ?? Influence of internal stresses on the disbondment of three layers coatings.

Keywords : pipeline coating-hot water-ageing-durability

Three layer polypropylene (3LPP) pipeline coatings failed prematurely in the oilfields of Abu Dhabi in the United Arab Emirates (UAE). A failure investigation and analysis into this phenomenon was instigated. The coating disbondment has been found to be due to high residual stress concentration and adhesion loss.

In this paper, failure analysis methodology will be applied to the principal mechanisms by which FBE coatings fail during long term service; with specific application to case studies involving blistering. The case studies apply standard failure analysis techniques to determine the primary causes and modes of failures.
