 The authors of the IEA 22 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 DNVGL Bladed model was developed by [DNV](mailto:[email protected]) and is available upon reasonable request.
-* A [QBlade](https://qblade.org) model was developed by researchers at [TU Berlin](https://qblade.org/contact/) and is available upon reasonable request.

+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 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.
