Offshore coatings for low-temperature applications

Organic coating systems have been investigated according to their performance under low-temperature offshore conditions. Three performance groups were considered: corrosion protection performance, performance under mechanical loads, and de-icing performance. The investigations involved the following tests: accelerated corrosion protection/ageing testing, anti-icing tests, tests for coating adhesion, impact resistance tests, hardness abrasion tests, and wettability tests. The test conditions were adapted to Arctic offshore conditions, which mainly covered low temperatures down to -60°C, dry-wet cycles, and UV radiation. A testing facility for rime ice accretion has been developed. Standard offshore test for corrosion protection assessment were partly modified. The coating systems investigated were organic coating systems which differed in generic coating material, number of layers, dry film thickness and application method.
