Abstract: A wind turbine blade extending in a longitudinal direction between a root end and a tip end and comprising a shell having an outer surface defining a pressure side and a suction side, a leading edge and a trailing edge, a chord having a chord length extending between the leading edge and the trailing edge and a load-bearing structure extending in the longitudinal direction, the wind turbine blade further comprises a dampening system comprising a blade dampening body attached exteriorly to the load-bearing structure or exteriorly to the outer surface of the shell, at least a first dampener located within the blade dampening body and positioned with a component in the chordwise direction of the blade and adapted to absorb vibrational forces the wind turbine blade is subjected to.
