This repository contains the model data for the 15 MW offshore reference turbine developed within IEA Wind Task 37.

The documentation for the turbine is accessable here: https://www.nrel.gov/docs/fy20osti/75698.pdf

Data in this repository includes:

• Documentation, including tabular data used in the figures from the technical report
• OpenFAST aeroelastic model inputs (compatable with OpenFAST-v2.3 available: https://github.com/OpenFAST/openfast.git)
• HAWC2 aeroelastic model inputs
• WISDEM optimization files
• Wind turbine ontology .yaml files
• CAD modeling of turbine in SolidWorks and an Ansys FEA model of the blades

Note that the OpenFAST model uses the NREL's Reference OpenSource Controller (ROSCO). Users will need to compile the dynamic library following the ROSCO install instructions and need to provide relavent path to the dynamic library within ServoDyn. Tools also exist for automatically retuning the controller, updating the "Cp_Ct_Cq.IEA15MW.txt" and "DISCON.IN" files that are inputs to ROSCO. The OpenFAST models are compatable with OpenFAST-v2.3.
