The floating or fixed foundations provide support for the wind turbine, transferring the loads from the turbine at the tower interface level to the sea bed where the loads react. The foundation also provides access for personnel from vessels. Unregulated vibrations result in excessive material wear, which in turn can (and does) cause component failure. Within the Glamox scope of vibration testing, three different types of test are performed: Sinusoidal vibration,various shock tests and random testing.
