Abstract: The present invention relates to a floating wind energy harvesting apparatus for offshore installation, comprising an elongated wind turbine body extending along a longitudinal wind turbine body axis; at least one blade attached to the wind turbine body for converting wind energy to rotation of the wind turbine body around the longitudinal wind turbine body axis; an energy converter coupled to the wind turbine body for converting the rotation of the wind turbine body to electrical energy; and a braking arrangement for controllably reducing a rotational speed of the wind turbine body. The braking arrangement comprises an inlet; an outlet; a water transporting arrangement coupled to the wind turbine body to transport water from the inlet to the outlet in response to rotation of the wind turbine body; and an access control arrangement for controllably preventing water from passing through the water transporting arrangement.

Abstract: A floating VAWT comprising a wind turbine body having a lower body portion and an upper body portion; at least one blade attached to the upper body portion for converting wind energy to rotation of the wind turbine body; and an energy converter attached to the wind turbine body for converting the rotation of the wind turbine body to electrical energy. The energy converter comprises a first energy converter part, and a second energy converter part to be kept relatively stationary in relation to the first energy converter part. The energy converter is attached to the wind turbine body by means of a first releasable mechanical coupling between the first energy converter part and the lower body portion of the wind turbine body, and a second releasable mechanical coupling between the first energy converter part and the upper body portion of the wind turbine body.
