INNWIND.EU scaled experiments of the OC4-DeepCwind semi-submersible

A floating wind test campaign was conducted within INNWIND.EU at LHEEA Nantes/France in 2014. The tested model is the OC4-DeepCwind semi-submersible in a scale of 1:45. The scaled 5MW rotor has re-designed blades with large chord to yield the Froude-scaled thrust force. In order to test also a 10MW system, wind/wave conditions of a scaling ratio of 1:60 were tested, with an adjusted rotor speed and blade pitch angle. The scaled model was modified in order to compensate the excess nacelle mass (due to actuators) by placing ballast underneath the original keel depth.
