Donghai Bridge Offshore Wind Farm Technology
The Donghai Bridge Offshore Wind Farm, commissioned in phases between 2009 and 2010, was a pioneering project in China for offshore wind energy. While specific details about the exact turbines used might be difficult to find due to the project's age, we can discuss some of the general technologies likely employed:
-
Turbines:
- Most likely utilized horizontal axis wind turbines (HAWTs), the most common design for wind energy conversion.
- Turbine capacity was likely in the range of 6 MW, which was a significant capacity for the time period.
-
Foundations:
- The farm likely used monopile foundations, which are single, large-diameter steel tubes driven into the seabed. This is a common foundation type for offshore wind farms in shallow waters.
-
Grid Connection:
- Undersea cables would have been used to transmit the generated electricity back to the mainland grid.
-
Operations and Maintenance:
- Service vessels would be used to access the turbines for maintenance and repairs.
