Description

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 DTU 10MW Reference Wind Turbine mounted on the SOFTWIND floater.

 

Update V2.0.0: Structure files are modified according to the requirements of the QBladeCE version

Update V3.0.0:
- Added controller from SOFTWIND experiments (Modified from DTU 10MW to have oO star controller parameters)
- Modified mooring line length
- Shifted platform COG slightly towards centerline
- Modified blade definition to AD14 blade def.
- Included STATICBUOYANCY flag

Update V3.1.0:

- Included ADVANCEDBUOYANCY flag
- Corrected excitation file (.3), previously: incorrect assignment of wave headings and excitation force coefficients
- Addition of mean drift file (.8)
- Corrected error in added mass matrix entry [4,2] (sway-roll coupling)

Notes

Version 3 corresponds to the SIL model (Software In the Loop) which ran in parallel to the wave basin experiments carried out in Nantes. Future updates of this model will be kept under version 3.x and incrementally increase the second digit. This version ought to be used when the wave tank experiments should be replicated. Version 4.x corresponds to a version where the wind turbine is not scaled up based on the physical model that exists in the wave tank but rather a purposely designed offshore wind turbine (DTU10MW) with a suitable tower (OO-Star). This version ought to be used when simulations in realistic met-ocean conditions are of interest.
