Modelling a gravitational launch of gravity based foundations for offshore wind turbines

This thesis focuses on modelling a gravitational launch of gravity based foundations (GBF's) for offshore wind turbines. This is an extension of the Blyth Offshore Demonstrator project by BAM Infraconsult. To become more competitive in the offshore wind energy market, the construction of self-buoyant GBF's installed using the `float and submerge...

Dynamic response analysis of a spar floating wind turbine in level ice with varying thickness

The wind energy industry in order to find stronger winds, has to go further offshore and move into deeper waters where bottom founded wind turbines cannot be deployed anymore. This is the main reason why floating wind turbines have been studied extensively in the past years. In the case of regions with cold climates, ice loads become significant...

Rational Upscaling and Modelling of a Semi-Submersible Floating Offshore Wind Turbine

Floating offshore wind turbines are taking on more and more prominence, as the industry moves towards larger turbines, farther offshore, in deeper water. The increase in turbine size can reduce the costs of offshore wind energy, but requires larger support structures. Rather than redesigning the structure completely, a rational methodology for...

Design of Monopile Foundations to Support the DTU 10 MW Offshore Wind Turbine

Further advancements in the offshore wind industry, which come with the use of larger wind turbines at deeper water, require larger support structures. For shallow and intermediate water depths, monopile foundations still remain the most widely-used and cost-effective support structure due to the relative simplicity of fabrication and...
