Offshore coatings protect surfaces in arctic environment

Friday, 7 February 2014

Different generic coating types have been investigated in terms of their surface protection performance under low-temperature offshore conditions.

One of the highlights at the European Coatings Conference "Marine Coatings” on 4/5 March 2014 is the presentation about "Offshore coatings for low-temperature applications” by Dr. Andreas Momber, Muehlhan AG, Germany. The investigations are part of the German, nationally funded Cluster Project "Production, Operation and Living in Arctic Regions” (POLAR).

Four major topics have been considered

1. Corrosion protection performance

2. Performance under mechanical loads

3. Icing/de-icing performance

4. Ageing effects.

The investigations involved the following tests: accelerated offshore ageing tests, rime ice formation tests, coating adhesion tests, impact resistance tests, wear tests, surface morphology tests, wettability tests.

A ranking of coating systems is suggested

The investigated coating systems differed in generic coating material, number of layers, dry film thickness and application method. Experimental design, test methodologies and test facilities are described, and the results of the investigations are discussed. Based on an assessment scheme, a ranking of coating systems is suggested regarding their protection performance under low-temperature offshore conditions.
