This progress is vital for the future of renewable energy, as offshore wind power plays a crucial role in the global transition towards a more sustainable and resilient energy system.

Survival Mode: Wind Turbines During Hurricanes

When hurricanes strike, wind turbines undergo specific safety measures called survival mode to protect themselves from the extreme winds. This ensures the structural integrity of the turbines and prevents any potential damage that could occur due to the high wind speeds associated with hurricanes.

During survival mode, the blades of the wind turbines are feathered, meaning they are rotated to a position where they offer the least possible resistance to the wind. This helps to minimize the impact of the strong gusts, reducing the risk of blade damage. Additionally, the turbines are shut down to prevent excessive strain on the components and to avoid power surges that could potentially cause further damage.

Once the hurricane winds subside, the wind turbines can resume normal operation. This process of entering and exiting survival mode is a critical safety measure that allows wind turbines to withstand the forces of hurricanes while protecting their long-term functionality.

It is worth noting that the effectiveness of survival mode in wind turbines during hurricanes has been observed in real-life scenarios. For instance, during winter storm Stella, wind speeds exceeded 70 mph at the Block Island Wind Farm. The turbines effectively entered survival mode and were able to power back up once the winds subsided, demonstrating their resilience in extreme weather conditions.

Wind turbine technology continues to evolve, and research efforts are focused on improving their resilience in extreme weather conditions.
