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...
متن کاملPerformance 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...
متن کاملIncremental wind-wave analysis of the structural capacity of offshore wind turbine support structures under extreme loading
Offshore wind turbine (OWT) support structures are subjected to non-proportional environmental wind and wave load patterns with respect to increases in wave height and with respect to wind and wave combined loading. Traditional approaches to estimating the ultimate capacity of offshore support structures are not ideally suited to analysis of OWTs. In this paper, the concept of incremental wind-...
متن کاملDesign of support structures for offshore wind turbines
Offshore wind is the logical next step in the development of wind energy. With higher wind speeds offshore and the fact that turbines can be placed out of sight, offshore wind helps increase the amount of renewable energy signifi cantly. Offshore wind has been developed through pilot projects in the 1990s and has seen commercial development over the last decade. This chapter shows the developme...
متن کاملPerformance based assessment of offshore wind turbine platform using the constrained new wave method
The purpose of this study is to provide a more accurate and practical method than static and spectral methods to assess the offshore wind turbines that are loaded with both wave and wind time history, the structure is evaluated by increasing the load intensity in successive steps to the stage of failure and the performance of the platform in different wave patterns are investigated. In this stu...
