WES - Hurricane eyewall winds and structural response of wind turbines

https://wes.copernicus.org/articles/5/89/2020

This paper describes the analysis of a wind turbine and support structure. subject to simulated hurricane wind fields. The hurricane wind fields, which result from a large eddy simulation of a hurricane, exhibit features such as very high gust factors (>1.7), rapid direction changes (30∘ in 30 s), and substantial veer. With a focus on blade root loads and tower base loads, the simulations show that these features of hurricane wind fields can lead to loads that are substantially in excess of those that would be predicted if wind fields with equally high mean wind speeds but without the associated direction change and veer were used in the analysis. This result, if further verified for a range of hurricane and tropical storm simulations, should provide an impetus for revisiting design standards." name="citation\_abstract">. # Hurricane eyewall winds and structural response of wind turbines.

Wind Turbines in Extreme Weather: Solutions for Hurricane Resiliency | Department of Energy

https://www.energy.gov/cmei/systems/articles/wind-turbines-extreme-weather-so…

An official website of the United States government. A **.gov** website belongs to an official government organization in the United States. Offshore wind turbines on the Atlantic coast (as well as the Gulf Mexico) have several challenges to contend with—including hurricanes. *This blog is part of a series that explores offshore wind technical challenges that are different in the U.S. than in other countries.*. The Energy Department is developing tools to help wind system designers lower the risk for offshore wind turbine systems located in extreme weather areas. However offshore wind turbines on the Atlantic coast (as well as the Gulf Mexico), have another challenge to contend with: hurricanes, which we’ll explore below. It is used for hurricane research and prediction to create a new “Coupled Hydro-Aerodynamic Interface for Storm Environments.” This tool helps wind system designers to lower the risk for offshore wind turbine systems located in extreme weather areas.

Quantifying the hurricane risk to offshore wind turbines - PMC - NIH

https://pmc.ncbi.nlm.nih.gov/articles/PMC3295275

An official website of the United States government. # Quantifying the hurricane risk to offshore wind turbines. The U.S. Department of Energy has estimated that if the United States is to generate 20% of its electricity from wind, over 50 GW will be required from shallow offshore turbines. We apply this model to estimate the risk to offshore wind farms in four representative locations in the Atlantic and Gulf Coastal waters of the United States. Offshore wind turbines in these areas will be at risk from Atlantic hurricanes. To illustrate the risk to a wind farm from hurricane force wind speeds, we calculate the expected number of turbine towers that buckle in a 50-turbine wind farm as a function of maximum sustained (10-min mean) wind speed, assuming that turbines cannot yaw during the hurricane to track the wind direction (we later consider the case in which the nacelle can be yawed rapidly enough to track the wind direction of the hurricane).

forces - Can we reduce a hurricane's power using wind turbines? - Physics Stack Exchange

https://physics.stackexchange.com/questions/197010/can-we-reduce-a-hurricanes…

Below is the abstract of an article in Nature: Taming hurricanes with arrays of offshore wind turbines, describing computer simulations that indicate that wind turbines could disrupt a hurricane enough to reduce peak wind speeds by up to 92 mph and decrease storm surges by up to 79 percent. Honeste\_vivere's answer mentions the possibility of destroying a farm, and the abstract includes "The reduction in wind speed due to large arrays increases the probability of survival of even present turbine designs." What seems to be missing at this level is the need to produce turbines which will work effectively at hurricane-force winds. My question is not about the financial, logistical or engineering challenges of building a large amount of wind turbines to "tame" hurricanes, as this is solely a computer model and it will probably be a classic case of a model saying "possibly" but in real life it will not happen.
