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 کاملComparison of Cyclic P-y Methods for Offshore Wind Turbine Monopiles Subjected to Extreme Storm Loading
Approximately 75% of installed offshore wind turbines (OWTs) are supported by monopiles, a foundation whose design is dominated by lateral loading. Monopiles are typically designed using the p-y method which models soil-pile resistance using decoupled, nonlinear elastic Winkler springs. Because cyclic soil behavior is difficult to predict, the cyclic py method accounts for cyclic soil-pile inte...
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 کاملRaft and Pile Foundations under Cyclic Loading
The paper presents typical phenomena which can occur due to cyclic loading in granular soil. Numerical analysis with different material laws shows the challenges to simulate the ground behaviour realistically. Results of numerical analysis by means of the Finite-Element-Method are presented and the limitation of material laws discussed.
