1. General description

This data set contains as-build design information, as well as full-scale vibration response measurements from an operational offshore wind-turbine. The turbine is part of the Norther wind farm which is located in the Belgian North Sea and includes a total of 44 Vestas V164 (8.4MW) wind turbines on monopile foundations, see Fig1_Norther_locaction.png. This data set is intended to verify and validate model-based virtual sensing algorithms, using data as well as modeling information from a real turbine.

1.1 Summary of the shared structural information

The included information entails a detailed description of the geometric properties of the monopile and transition piece, distributed and lumped structural masses . All information shared in this record is conform the as-designed documentation. An example of the lumped masses considered in the model input files is presented in "Fig2_Sensor_Network.png"

1.2 Summary of the shared geotechnical information

Monopiles are distinguished by the significant role of soil-structure interaction. Ground reaction is most typically included in the structural model as non-linear p-y curves. Different p-y curves are available for a certain number of soils in the standards applicable to offshore structures (API RP 2GEO, 2011, and ISO 19901-4:2016(E), 2016).

The required soil properties to define p-y curves according to the API framework are given in the soil profile provided in a separate Excel. Rather than symbols, the name of the soil properties is generally used as column header (e.g., Undrained shear strength). Therefore, it is straightforward to identify each soil parameter. The only soil parameter that might lead to confusion is:

"epsilon50 [-]" represents the vertical strain at half the maximum principal stress difference in a static undrained triaxial compression test on an undisturbed soil sample.

It's worthy to note that estimates for the small shear strain stiffness, referred to as Gmax, are
