Determination of Fatigue Assessment of Monopile - Based Offshore Wind Turbines through Fidelity Quantification

The application of stability checks in simulated offshore wind structures is performed through tools that are established in the offshore wind industry. In particular, the structure should fulfill certain strength and fatigue criteria among which Fatigue Limit States (FLSs) checks are critical. In terms of the process, fatigue assessment can be...

Response of an Offshore Wind Turbine supported by a Non-Local Winkler Foundation: An Efficient 1D Time-Domain Model accounting for the 3D Frequency-Dependent Dynamic Soil Stiffness

With increasing evidence of human-induced accelerated climate change, the need of sustainable, non-polluting, energy sources becomes evident. Offshore wind generated electricity is currently one of the most promising sources of energy to create a sustainable global energy mix. The offshore wind industry has developed rapidly over the last years....

Capturing 3D Continuum Effects in a 1D Soil-Structure Interaction Model for Seismic Analysis of Offshore Wind Turbines

Offshore wind energy is considered a necessary energy resource, that may stimulate the transition from fossil fuels. Following the successful development in Western Europe, offshore wind is quickly gaining momentum in the Asia-Pacific region. At variance with North-Sea based offshore wind turbines (OWTs), structures installed in the Asia-Pacific...

On the Assessment of Equivalent Hysteretic Damping on Offshore Wind Turbines Subjected to Seismic Excitations

The increasing global demand of renewable and clean energy has led to the exponential growth, development, and interest in the offshore wind energy industry and expansion towards earthquake-prone areas. Offshore wind turbine structures, typically supported by a tubular monopile foundation, are increasing in size to meet the increasing human...
