High Voltage Direct Current (HVDC)

Protection against marine biofouling for offshore wind farms

Globally, offshore wind is fast becoming a leading source of renewable energy. It is critical that the technology powering offshore plants meets performance requirements and addresses the changing operational needs of these complex environments.  

To ensure operational efficiency for wind farms, high-voltage direct current (HVDC) technology is utilized. HVDC transmission systems are housed on platforms in the sea, making them subject to ever-changing weather conditions and temperature extremes. ​Along with the ever-changing weather conditions and temperature fluctuations, biofouling can pose a significant problem for offshore wind power. The cost of operation, infrastructure, and the maintenance of offshore platforms are some issues, however there are also considerations for fish health, biosecurity, and damage to the aquaculture environment.
