New test series begins on FINO2






New test series begins on FINO2


In the middle of the Baltic Sea, around 40 km from Rügen, in a large offshore wind park – this is the location of the FINO2 research platform. Since 2013 Dörken has been using the opportunity to expose coated components to the aggressive maritime climate here - and test them for their corrosion resistance. Colleagues Florian Feldmann and Markus Nowak took us with them to install the components for the new test series.

Dörken of Herdecke began outdoor weathering testing on the FINO2 in 2013, in co-operation with DNV GL – Germanischer Lloyd SE. The goal of the series is to test the surface coating of components as realistically as possible. The findings of these tests are particularly relevant and interesting for components used in maritime onshore and offshore areas, as they are exposed to extreme stresses: rain, salt water, snow, heat, cold and UV rays. These are joined by extremely high winds and diverse environmental conditions such as temperature fluctuations and humidity. Components in use here need to withstand this climate for years. And what better location to “simulate” the influence on corrosion coatings than on the FINO 2?

Following the installation of screws in 2013, a new test series has now been initiated with metal sheets. These are coated with diverse coating systems from Dörken as well as reference systems and also partially subjected to scoring, to simulate corrosion behaviour on previously damaged components. The experiment is based upon the valid DIN EN ISO 12944, to ensure the corrosion protection of steel structures.

The FINO2 platform is not only hard on the components exposed on it: to install, monitor and analyse the test series it is first necessary to travel to the platform by ship and then a small inflatable, before climbing a ladder to 12.5m and 25m above mean sea level. Fortunately, our colleagues have strong nerves and a head for heights.
