OffshoreOffshore windOffshore wind turbineWind turbine towers towersWind turbine (without rotor-nacelle assembly) temporarily arranged in groups on port quaysides for the pre-assembly operations are very sensitive to wind loadsWind loads. Moreover, the large number of parameters makes wind tunnelWind tunnel testsWind tunnel test the main way to address the problem. Nevertheless, the simulation of the high Reynolds numberHigh Reynolds number expected for the towers at full scale represents a crucial challenge for any wind tunnelWind tunnel facility, asking for large models and suitable surface roughness strategies. Another source of inaccuracy in the measured dynamic loads may arise from the moderate stiffness of the tower physical models mounted on a high-frequency force balance, requiring low-pass filtering. The wind tunnelWind tunnel mismatch of the integral length scale of turbulenceTurbulence, often dictated by the need to keep the geometric scale of the model as large as possible is also an issue to consider carefully. In the present work, the wind tunnelWind tunnel results for an isolated tower and for a few groups of towers in close proximity are revisited based on a simple gust-buffeting model, aiming at quantifying the dynamic effects of the abovementioned imperfect physical modelling and determining the associated correction factors.
