This repository contains the model data for the 22-MW offshore reference turbine developed within IEA Wind Task 55 REFWIND.
The documentation for the turbine is available here: https://doi.org/10.11581/DTU.00000317.
Data in this repository includes:
- Documentation, including tabular data used in the figures from the technical report
- OpenFAST aeroelastic model inputs
- HAWC2 aeroelastic model inputs
- WISDEM optimization files
- WindIO turbine ontology .yaml files
- CAD modeling of turbine where available
OpenFAST:
- Please check the release notes for OpenFAST version compatibility. OpenFAST can be compiled from source here or precompiled Windows binaries are available for download. More information on installing and running OpenFAST is available in OpenFAST documention.
- NREL's Reference OpenSource Controller (ROSCO) is required. This can be compiled from source here or precompiled binaries for all platforms are available for download. The version of the ROSCO controller can be found in the header of the DISCON.IN
HAWC2:
- HAWC2 can be acquired from its homepage. The DTU Basic Controller can be obtained from its repository.
WISDEM:
- WISDEM can be installed from its Github repository.
- See the documentation for installation and usage guides.

The authors of the IEA 22 MW RWT hope that the turbine is used widely. Notable studies adopting the turbine will be listed here, together with models of the turbine implemented in other codes:
- A Bladed model was developed by DNV and is available as part of the Bladed v4.16 installation. DNV have also written a Python converter tool for the WindIO blade definition to Bladed format for the IEA 22 MW RWT.
- A QBlade model was developed by researchers at TU Berlin and is available in this repository.
- An OrcaFlex model of the v1.0.1 22 MW rotor, nacelle, and tower (no foundation) was developed by Orcina and verified against OpenFAST. The report and model are available on the validation page of the Orcina website.
The IEA 22 offshore reference wind turbine was made possible thanks to countless inputs from a long list of collaborators. A non exhaustive list includes Mayank Chetan and Emmanuel Branlard at NREL, William Collier and Dilek Ors at DNVGL, David Marten at TU Berlin, and Georg Pirrung, David Verelst and Katherine Dykes at DTU. DTU's participation in IEA Wind Task 37 and Task 55 is sponsored by the Danish Energy Agency under contract no. EUDP-64019-0588 and EUDP-134234-512032. We also wish to acknowledge Equinor for sponsoring a co-financed research project, which formed the basis for the IEA 22 MW RWT rotor design. A portion of this research was performed using computational resources sponsored by the Department of Energy's Office of Energy Efficiency and Renewable Energy and located at the National Renewable Energy Laboratory. This work was authored in part by the National Renewable Energy Laboratory, operated by Alliance for Sustainable Energy, LLC, for the U.S. Department of Energy (DOE) under Contract No. DE-AC36-08GO28308.
