Study on Load-Bearing Characteristics of a New Pile Group Foundation for an Offshore Wind Turbine
Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...
متن کاملFoundation damping and the dynamics of offshore wind turbine monopiles
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 کاملCentrifuge modelling of long piles subjected to lateral loading with high load eccentricity in sand
In this research paper, five centrifuge lateral loading tests of long piles with a considerable load eccentricity were carried out in the sand to investigate the impacts of the load eccentricity and pile length changes on the lateral behavior of a flexible pile beside the determination of experimental p-y curves. Comparing experimental test results with the recommended API (American Petroleum ...
متن کاملThe Behavior of Suction Bucket under Cyclic Loading in Saturated Lands
Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...
متن کاملPreliminary Design of a Multi-Column TLP Foundation for a 5-MW Offshore Wind Turbine
Currently, floating wind turbines (FWTs) may be the more economical and suitable systems with which to exploit offshore wind energy in deep waters. Among the various types of floating foundations for offshore wind farms, a tension leg platform (TLP) foundation can provide a relatively stable platform for currently available offshore wind turbines without requiring major modifications. In this s...
