Current and wave effects around windfarm monopile foundations
Laboratory measurements were undertaken to investigate wave and current velocities in the vicinity of a wind turbine monopile foundation, in order to inform environmental impact assessments and to quantify flow variability in the region of the power take off cable. Flow measurements were made up to 15.5 pile diameters (D) downstream of the pile. Measurements were also taken around the perimeter...
متن کاملSoil–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 کاملFinancial Regulation in the United Kingdom:Historical Foundations and Current Practices
Financial markets have been developed rapidly in recent years. New and sophisticated financial tools have been the cause of these developments which need new controlling systems to prevent crisis. Most of industrial economies have reformed regulatory structure of their financial systems. This paper reviews the regulatory developments of UK in this regard and offers new regulations and ...
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 کاملThe nature of scour development and scour protection at offshore windfarm foundations.
Analysis and interpretation of monitoring data for the seabed bathymetry local to offshore windfarm foundations has shown how the scour develops in time and highlighted variations between sites with different seabed sediment characteristics, i.e. sands and clays. Results from European offshore windfarms have generated a unique dataset for comparison with previously published data. Where surfici...
