The climate change potential of steel support structures for offshore wind turbines: An assessment of monopile and jacket support structure steel mass and greenhouse gas emission development for offshore wind turbines in the North Sea

Offshore wind electricity generation will play a key role in the transition to a sustainable energy sector. In 2020, the European Commission presented their Offshore Renewable Energy Strategy which includes 300 GW of offshore wind capacity by 2050 (European Commission, 2020). This research focusses on the steel mass development of OWT structural...

Frequency Domain Fatigue Analysis of Offshore Wind Monopile Support Structure: For the Purpose of Offshore Wind Farm Optimization

The preliminary design of wind turbine support structures within an offshore wind farm plays a significant role in decreasing the costs involved and is pivotal in establishing the wind sector as a leading contributor towards a sustainable future. During the early design stages, the optimization of structural dimensions, which involves a large...

Analytical model to assess bending moments in wind turbine support structures subjected to ship collisions

The number of offshore wind farms is growing rapidly, which increases the likelihood of ship collisions with offshore wind turbines. Additionally, the cost of energy reduction for wind turbines is achieved due to radical design optimizations. Therefore, simple methods should be obtained to determine the offshore wind turbine response during ship...

Definition and Response Validation of a Simplified Aero-Servo-Elastic Wind Turbine Model

Currently, the foundation design of offshore wind turbines is based on a simple cantilever beam model with a mass representing the rotor and nacelle, or by making use of wind turbine simulation software such as Bladed, which are built for rotor design. The simple models are unrealistic since the dynamic interaction between the aerodynamic loads,...
