Soil–structure reliability of offshore wind turbine monopile foundations
An overview of offshore wind turbine (OWT) foundations is presented, focusing primarily on the monopile foundation. The uncertainty in offshore soil conditions as well as random wind and wave loading is currently treated with a deterministic design procedure, though some standards allow engineers to use a probability-based approach. Laterally loaded monopile foundations are typically designed u...
متن کاملReliability 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 کاملDynamic Analysis of Offshore Wind Turbine Towers with Fixed Monopile Platform Using the Transfer Matrix Method
In this paper, an analytical method for vibrations analysis of offshore wind turbine towers with fixed monopile platform is presented. For this purpose, various and the most general models including CS, DS and AF models are used for modeling of wind turbine foundation and axial force is modeled as a variable force as well. The required equations for determination of wind turbine tower response ...
متن کاملSoil-Structure Modeling and Design Considerations for Offshore Wind Turbine Monopile Foundations
The contribution of foundation damping to offshore wind turbines (OWTs) is not well known, though researchers have back-calculated foundation damping from “rotor-stop” tests after estimating aerodynamic, hydrodynamic, and structural damping with numerical models. Because design guidelines do not currently recommend methods for determining foundation damping, it is typically neglected. This pape...
متن کاملThe Effect of Lateral Loading Parameters on Monopile Behavior Based on Physical Modeling
Monopiles are the most common type of foundation for offshore wind turbines (OWT). Monopiles have been used in more than 80% of the offshore wind turbines. A monopile will be affected by millions of lateral load cycles during the operating period, which will cause its rotation and lateral deformation. The rotation and the deformation are dependent on the soil properties, monopile specification,...
