Having helped to draft the ASCE/AWEA RP2011 and serving currently as "Designated US Expert" on the IEC TC-88 committee in charge of developing IEC61400-6, we are intimately familiar with industry accepted practice and design standards and guidelines relevant to the wind energy industry. We are familiar with the loads side as defined in IEC61400-1 and the interpretations of North American material codes to achieve intended design reliability.
