The demand for high temperature (120° C < T ≤ 150° C) protective coating systems for offshore service has proliferated due to the increase in high-temperature pipelines developments in the Asia Pacific and Gulf of Mexico regions. Three-layer Polypropylene coating system are typically used as anti-corrosion coatings for offshore pipelines as they are capable of withstanding operating temperatures as high as 150° C and they are resistant to water and mechanical damage. Recently, there is an increasing interest in using standalone fusion bonded epoxy coatings, single or dual-layer systems, for high-temperature offshore services. Despite the recent progress in FBE technology, questions remain on the long-term suitability of such systems for offshore high-temperature environments.

This paper discusses the performance of different high-temperature fusion bonded epoxy (HT FBE) coating systems subjected to simulated service testing. An assessment protocol is introduced for HT coating systems for offshore pipelines.
