Modelling offshore sand wave evolution
Web20 apr. 2012 · In this study, two types of floating offshore wind turbine (FOWT) systems were proposed: a traditional tension leg platform (TLP) type and a new TLP type with additional mooring chains. They were both based on the National Renewable Energy Laboratory 5 MW offshore wind turbine model. Taking the coupled effect of dynamic … Web2 aug. 2024 · Using this model, we are able to investigate storm effects on sand wave evolution. The modeled equilibrium sand waves in tide + wave + wind conditions become about 15 m high and 600–1,000 m in wavelength, migrate at about 50 m/year, and are formed in roughly 10 years.
