When a significant percentage of wind turbine housings from a major U.S. manufacturer experienced failures in their first eighteen months of operation, Structural Integrity Associates was retained by an operator of the turbines to perform an independent assessment of the manufacturers root cause analysis, and to provide recommendations for potential remedies. The failure investigation resulted in a thorough understanding of the cause of the problem, and ultimately led to recommended operational restrictions and metallurgical treatments which permitted the wind field to continue operating at an acceptable, statistically established failure rate.
