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 کاملSimilitude relationships for physical modelling of monopile-supported offshore wind turbines
Offshore wind turbines are considered as an important element of the future energy infrastructure. There is currently a surge in the construction of such facilities in Europe, yet there is no track record of long-term performance of these structures. Offshore wind turbines are dynamically sensitive structures because of the very nature of the structural form (tall and slender) and the different...
متن کاملAn Investigation into the Effect of Scour on the Loading and Deformation Responses of Monopile Foundations
Severe foundation scour may occur around monopile foundations of offshore wind turbines due to currents and waves. The so-called p-y curves method is suggested in the existing design recommendations to determine the behavior of monopiles unprotected against scour and the reduction of effective soil stress is accounted for by the extreme scour depth. This conservative design approach does not co...
متن کاملNumerical and Experimental Modeling of Scour at Foundation Structures for Offshore Wind Turbines
There is presently a lack of knowledge of scour progression for complex offshore foundation structures, such as Tripod foundations for offshore wind turbines. Typically, scour is investigated in physical model tests. As an extension, parts of the investigations could be carried out by using numerical methods; however, such numerical methods require that all relevant processes leading to scour a...
