S.163-174 Eight organic coating systems have been investigated according to their performance under Arctic 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 and ice adhesion, impact resistance tests, hardness measurements, 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. Testing facilities for icing/de-icing performance tests have been developed. Standard offshore tests 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. The first part reports about experimental design, the test methodologies, and test facilities used. The second part discusses the results of the investigations. Based on an assessment scheme, a ranking of coating systems is recommended regarding their protection performance under Arctic offshore conditions. The investigations are part of a nationally funded Cluster Project ""POLAR"" (Production, Operation and Living in Arctic Regions).
