Concrete Technology for Offshore Wind Turbine Structures

Reliability analysis of monopile offshore wind turbine support structures

We probe the reliability of monopile support structures designed to support industrial scale turbines along the coastal United States using stochastic models for the wind and wave loadings, and representations of the uncertainty associated with soil properties. The turbine support structure investigated is that promulgated by the National Renewable Energy Laboratory as typical of a monopile sup...

Performance Levels and Fragility for Offshore Wind Turbine Support Structures during Extreme Events

Successful development of the offshore wind energy resource depends upon the reliability of the structures that support the electricity-generating rotor-nacelle assemblies that form the core of a wind turbine system. The risk posed to offshore wind turbines (OWTs) by extreme environmental events such as Atlantic hurricanes requires a more detailed examination of post-elastic structural performa...

Robust Requirements and Design Optimization for Offshore Wind Turbine Structure Utilizing Approximate Model Technology

We discuss the robust design optimization (RDO) of the support structures of offshore wind turbines to decrease costs and variations considering uncertainties. First, an approximate model derived with design of experiment (DOE) methodology is introduced to replace the time-consuming computational dynamic response analysis of finite element (FE) models for reducing computational costs. Then, a d...
