IEA-15-240-RWT v1.1 (Revised February 2022)

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 accessible here: https://www.nrel.gov/docs/fy20osti/75698.pdf and the semisubmersible floating support structure is documented here: https://www.nrel.gov/docs/fy20osti/76773.pdf

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
• Wind turbine ontology .yaml files
• CAD modeling of turbine where available

Requirements

OpenFAST:

• The OpenFAST input files are compatable with OpenFAST-v3.0. This 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.

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.

Design Updates

The IEA Wind Task 37 authors endeavor to keep the model input decks current with the latest releases and API changes. Errors and other issues pointed out by the community are also addressed to the extent that available resources make that possible. See the Release Notes for a detailed description of changes.

We also encourage the broader wind community to submit design updates by forking the repository and letting us know of your design customatization. Community contributions that we are aware of include:

• Bladed implementation
• OrcaFlex implementation

Questions

Before reaching out to NREL or DTU authors with questions on the model or reports, please see our frequently asked questions (FAQ) on our Github Wiki and current or prior Issues.

If neither the FAQ or Issues address your need, please create a new Issue on this repository so that the dialogue is archived for others that might have similar questions. You can also reach out to the authors directly if that is your preference. The technical report lists the contributions of individual authors if you have a specific question. Otherwise, you can contact Garrett Barter (garrett.barter@nrel.gov).
