For the detailed validation and verification of the capabilities of QBladeOcean in work package 2 of FLOATECH, a detailed definition of the models is needed. This database presents the QBladeOcean model of the MARIN Stock Wind Turbine mounted on the OC5 floater. Update V2.0.0; Structure files are modified according to the requirements of the QBladeCE version Update V3.0.0; Bugfix mooring line 3 definition Update V4.0.0;- TOWERDRAG activated and set to cd = 0.5- Inlcusion of Non-linear QTF forces- Modified RAYLEIGHDMP 0.05 --> 0.01 Update V5.0.0;- updated Substructure .dat file to a format compatible with QBlade version 2.0.6.4+- extrapolation stretching activated- depth dependent drag coefficient of 0.6 until z = -4m- enhanced model to improve low frequency pitch excitation --> additional parameters in HYDROJOINTCOEFF table- adjusted "DAMP_[-]" paremeter in the "MOORELEMENTS" table of the Substructure .dat file to be zero due to numerical instabilities

This model is used in the WES publication: "Quantifying the Impact of Modeling Fidelity on Different Substructure Concepts for Floating Offshore Wind Turbines - Part I: Validation of the Hydrodynamic Module QBlade-Ocean". In the current setup of the turbine model, it corresponds to the "QB2" model shown in Figure 14. The extended capability to capture non-linear motions/loads is set up in the HYDROJOINTCOEFF table of the substructure file. This functionality is ignored by the current version of QBladeCE, but will be included in the next release. The models required to run the decay and isolated hydrodynamic excitation test cases can be easily derived from this model.
