Hurricane Risk to Offshore Wind Turbines Along the U.S. Coast
Stephen Rose, Paulina Jaramillo, Mitchell J. Small, Iris Grossmann, and Jay Apt

Abstract:
This paper applies the method developed by Rose, et al. to create a map of the hurricane risk to offshore wind farms along the Atlantic coast and Gulf coast of the U.S. The risk to offshore wind farms is lowest along the coast of Mid-Atlantic and New England regions. There is less than a 10% probability in those regions that hurricanes destroy more than 10% of a wind farm in 20 years in most counties. The risk to offshore wind farms is highest for counties along the Gulf of Mexico, in South Florida, and near Cape Hatteras, NC. There is greater than a 30% probability in those regions that hurricanes will destroy more than 10% of a wind farm in 20 years. The hurricane risk to offshore wind farms can be significantly decreased by adding backup power to ensure the turbines are able to rapidly yaw to point directly into the wind even when grid power has been lost.
