Offshore wind farm decommissioning: An orientation of possible economic activity in the south holland region and the rotterdam port area

A significant part of wind energy in the Netherlands is generated by offshore wind farms at sea. In the coming decades, the number of wind farms will be scaled up in line with current energy transition and sustainability objectives. What happens to these wind turbines when they reach the end of their operational life? What volumes of material...

Support Structure Optimization: On the use of load estimations for time efficient optimization of monopile support structures of offshore wind turbines

Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...

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...
