Smalls drops, big impact: Even just minor rain erosion damage on rotor blade surfaces can impair performance and shorten the service life of wind turbines. Fraunhofer IWES has been operating a rain erosion test bench since 2015 in order to achieve a better understanding of how damage progresses and derive effective preventative measures. Within the scope of the newly started “BeLeB” research project the aim is to contribute to the development of reliable forecasting models for erosion damage and apply them to turbine operation. In particular, this also encompasses the assessment of practice-relevant repair concepts. To achieve these goals, the test bench is set up to enable continuous testing and precise damage documentation by means of high-resolution 3D images. Offshore operating data are used by way of comparison for validation purposes. When operating, the wing tip of a wind turbine can reach speeds of 300 to 350 km/h and, as a result, rain drops and pollution in the air act like sandpaper on the surface of the material. Parts which are subjected to particular stresses, such as the leading edge of blades, are therefore finished with protective systems such as paint and coatings. The development and validation of a method for

Ampelmann, the global leader in offshore access solutions, has created, in cooperation with Seaway Heavy Lifting, an industry first innovation allowing workers safe and efficient access to install the jackets for 84 wind turbines on the Beatrice Offshore Windfarm Limited project in the Outer Moray Firth. Global offshore contractor Seaway Heavy Lifting awarded the EPCI contract to Ampelmann to design and create an Angular Boom Tip. This will allow secure connection at difficult angles for safe gangway transfer between the 5,000 tonne heavy lift vessel (HLV) Oleg Strashnov and the 2,500 tonne HLV Stanislav Yudin to install 84 individual wind turbines. Conventional gangway tips are rounded which can fit on the majority of offshore wind turbines or offshore assets. However, due to the size of the HLV, its close proximity to the jackets and the location of its access gates, Ampelmann custom-made the V-shaped tip at the end of the 25-metre gangway to give workers easy access to build and manage each new wind structure. Friso Talsma, Ampelmann’s Manager Sales and Business Development for Offshore Wind said: “Though the tip is a quite a straightforward piece of steel, the rubber covered angular shape now allows us to land at difficult angles as small
