Korrosionsschutzsysteme für Offshore-Windkraftanalagen - vergleichende Feld- und Laboruntersuchungen
Abstract
Off shore wind power plants have special requirements to corrosion protection systems because of the complex environmental impact and the operating efficiency. The presented investigations are focussed on the highly loaded areas of the tower construction (splash zone, water transition zone and near submerged zone). In this investigation field and laboratory tests in combination with electrochemical investigations have been performed. The Field tests were carried out on Helgoland over 3 years. The design of the coated test samples was related to constructive aspects of the tower (weld seams, screw couplings, coating transitions, overlaying coating edges, a.s.o.). As laboratory standard tests like ISO 20340 which is a special test evaluated for off shore applications, furthermore ISO 15711 and ASTM G 8 for cathodic disbonding. Additional investigations to the degradation of the coatings have been performed with electrochemical impedance spectroscopy.
