Seal-Inspired Sensors To Safeguard Offshore Wind Farms

Researchers at the University of Texas at Dallas have developed a unique sensor inspired by the whiskers of seals to improve the safety of offshore wind turbines. 

Seals rely on their highly sensitive whiskers to detect even the slightest vibrations in their environment, allowing them to hunt in the dark depths of the ocean. Dr. Yaqing Jin, assistant professor of mechanical engineering, UT Dallas, has adapted the geometry of these whiskers—twisted cylindrical shapes—into a cutting-edge sensor to detect changes in water flow. “The shape of the whiskers allows seals to sense their environment very effectively. We can replicate that design to create sensors that detect disturbances in the water, which could help prevent accidents in offshore wind operations,” Dr. Jin explained. This innovative sensor could be a game-changer for operators and engineers in the offshore wind energy sector, providing crucial data on ocean conditions that could prevent potential damage to turbines.

In the lab, the research team are testing their whisker-inspired sensor in a specially designed water channel. The setup simulates ocean conditions by circulating water at various speeds, enabling the team to observe how their sensors respond to shifts in water movement. This process could provide valuable insights for offshore wind operators, enabling them to anticipate and respond to hazardous conditions before damage occurs.

Traditional sonar systems  use sound waves that can disturb marine life, whereas these new sensors are sensitive to vibrations, offering a more environmentally friendly and efficient solution for monitoring underwater turbulence. This innovation could help protect both the marine ecosystem and the expensive offshore wind turbines that are critical to the growing renewable energy sector.

As offshore wind energy becomes increasingly important, particularly as it generates more power than land-based turbines, reliable monitoring technology is vital. Storms and turbulence in the deep ocean can be dangerous for floating wind turbines. These sensors, capable of detecting shifts in water movement, could provide early warnings, allowing operators to secure turbines and prevent costly damage. The research also includes developing sensors to protect the turbine blades and towers from wind damage.

The research work aligns with global efforts to expand renewable energy, as wind energy becomes a leading clean energy source. “Offshore wind production has enormous potential,” Jin said. “As this field grows, technologies like these sensors will be critical for ensuring the safety and efficiency of offshore wind farms.”
