Design/Construction of Fixed Bottom Turbines

The majority of the studies in this category focused on design and construction considerations for fixed bottom wind turbines, primarily with monopile foundations. Valuable information was provided for upcoming wind farm projects in areas with little past research:

  • Cost estimation for construction and decommissioning;
  • Scour around monopiles; and
  • Cable design.

This category also addressed interrelated structural design issues, focusing on the unique risks to offshore wind farms on the Outer Continental Shelf (OCS), including:

  • Hurricane loading;
  • Vibrations and turbine periods;
  • Fatigue; and
  • Lateral loads under cyclic loading

More research is needed to address similar issues with other foundation types.
