Failures and Reliability in Hawts Operating in Mountainous Areas, Open Sea and in Harsch Climate Sites

Recently, offshore wind plants, as Horn’s Riv one, have reached a remarkable interest and development. In these sites, HAWT’s blades experiment corrosion, erosion fouling and, at higher latitudes, icing conditions too, in mountainous areas harsch climate sites. The operative may influence the machine damages they occur consequence of erosion, fouling, icing, exfoliation caused by above mentioned environmental conditions. paper reports about data collection failures occurred to HAWTS operating offshore, sites last ten years. Particularly, damage blades, gears bearings been examined consequences analysed. are reliability WTGs is assessed appropriate models analysis. results com pared literature be very useful programmable maintenance predictable one. Reliability analysis also increase energy production.
