Open-accesss database for meta-models for fatigue calculations of reference wind turbines

This open-access data base contains developed Kriging meta-models for the fatigue load prediction as well as the corresponding training and test data of various reference wind turbines. The data base is published alongside the conference article “An open-access database for meta-models for fatigue calculations of reference wind turbines” by Schmidt et al., submitted in January 2026 to the TORQUE conference.

Meta-models and training and test data are published for the following reference turbines:

* NREL 5 MW reference turbine (Jonkman et al., 2009) on the OC4 jacket (Popko et al. 2012) in operating conditions. Simulations were conducted using an adapted version of the FASTv8 simulation code by the NREL (Jonkman, 2013) considering soil-structure-interaction (Häfele et al. (2016), Hübler et al., 2018).

* NREL 5 MW reference turbine (Jonkman et al. 2009) on the OC3 monopile (Jonkman and Musial, 2010) in operating and idling conditions. Simulations were conducted using an adapted version of the FASTv8 simulation code by the NREL (Jonkman, 2013) considering soil-structure-interaction (Häfele et al. (2016), Hübler et al., 2018).

* WindPACT 3 MW reference turbine (Rinker and Dykes, 2018) in operating and idling conditions (onshore).

* WindPACT 1.5 MW reference turbine (Rinker and Dykes, 2018) in operating and idling conditions (onshore).

* WindPACT 750 kW reference turbine (Rinker and Dykes, 2018) in operating and idling conditions (onshore).

Further information on the meta-models can be found in the headers of the training and test data files and in the references cited there.
