The data set provided contains the OpenFAST (V.3.5.3) input files for the Senvion 5M offshore wind turbine (OWT) of the alpha ventus wind farm. The OpenFAST model was developed based on a previously implemented Flex5 model of the Senvion 5M and includes the structural and aerodynamic properties of the real blades as well as the fully functional blade-style turbine controller in a 32-bit version.
A similar version of the OpenFAST model provided here was validated in [1] against measured data from the alpha ventus wind farm. However, the model of the jacket substructure (OWEC Quattropod) used for validation in [1] is not part of the model provided here due to confidentiality reasons. Instead, a reduced representation consisting of mass, damping and stiffness matrices is used to represent the substructure. With this reduced representation of the substructure, it is not possible to calculate the hydrodynamic forces.
The turbine model was originally implemented in Flex5-Poseidon by the University of Stuttgart - Stuttgart Wind Energy (SWE) based on documentation provided by Senvion and OWEC Tower. Further details on the Felx5 model and its validation can be found in [2].
This dataset is part of the RAVE (Research at alpha ventus) dataset and is of confidential nature. In order to obtain the dataset a data user agreement has to be signed which is provided by the BSH (Bundesamt für Seeschiffahrt und Hydrographie). Once the agreement is signed access to the data set is provided with a URL link. Until then, the data files are not visible and only metadata is available.
Please send the user agreement to the following address:
