Reliability Based Design Methodology for Extreme Responses of Offshore Wind Turbines;Doctoral thesis

摘要

Offshore wind energy has emerged as a viable supplement to onshore wind energy. Large scale offshore wind power plants will contribute significantly to the share of renewable energy in the future energy mix. The structural design of the offshore wind turbine faces new challenges from the harsh offshore environment of the North Sea. One of the additional design aspects that onshore wind turbines have not confronted before is the hydrodynamic loading. The combined extreme wind and wave loading can be an important issue for the structural design. It has been shown that an extreme load condition does not necessarily lead to extreme response of the offshore wind turbine. In this study, the emphasis will be on the extreme response of offshore wind turbines.
