Modelling and Control of Lateral Wind Turbine Tower Dynamics

In recent years wind turbines have become increasingly large to increase energy yield and cost-effectiveness. This has led to taller turbine towers, subjected to larger loads. As a result, Lagerwey turbines experience lateral tower vibrations at different resonance frequencies. These vibrations result in rotor speed measurement disturbances due...

The material damping of an offshore composite 10MW wind turbine tower

The dutch government plans to build a vast amount of offshore wind turbines. Therefore, it will be necessary to decrease the costs of the transportation, installation and maintenance of these wind turbines. Jules Dock tries to achieve this by replacing the steel design of the next generation 10MW wind turbine tower by a flexible composite design...

Finite Element 3D Modelling of Soil Dissipation in Suction Installed Wind Turbine

A realistic description of soil-foundation interaction in offshore wind turbines (OWT) under environmental loading requires deep understanding, and modelling capabilities for, saturated soil behaviour in presence of cyclic loads and pore pressure effects. <br/>This research investigates the dynamic energy dissipation occurring in the soil under...
