Floating offshore wind turbine with tuned mass dampers

摘要

A floating offshore wind turbine comprises a rotor with a plurality of blades, a nacelle and a nacelle support structure having a central longitudinal axis. A plurality of tuned mass damping configurations is arranged around the central longitudinal axis of the nacelle support structure to dampen vibrations in all 6 degrees of freedom.

1. A floating offshore wind turbine, comprising:
a rotor with a plurality of blades, a nacelle, and a nacelle support structure, the nacelle support structure comprising at least a wind turbine tower and a buoyancy structure, the nacelle support structure having a central longitudinal axis, wherein a plurality of tuned mass damping configurations is arranged radially outward from the central longitudinal axis and attached to the nacelle support structure, and the nacelle support structure further comprising a transition structure arranged between the wind turbine tower and the buoyancy structure, and a plurality of braces extending radially outward from the transition structure, wherein one tuned mass damping configuration is placed inside each brace.
