Numerical simulations are widely used for response calculations on offshore wind turbines. Code-to-code comparisons are frequently used for verification of the codes, as full-scale measurements can be difficult to obtain. However, most code comparisons performed focus on documenting the responses predicted by the different codes, or on the effect of specific differences between the codes. Little insight...
The present work identifies the qualitative hydro-elastic contributions to fatigue damage on large volume monopiles intended for use in the offshore wind energy industry. Although aerodynamic effects cannot be neglected in a complete dynamic analysis of the structure, the scope of this work is limited to wave loads and soil effects on a turbine in simplified operational conditions. As the rotors are...
Offshore bottom-fixed structures, such as jackets, are typically designed with a natural period of 3 seconds or less. This means that there is limited dynamic excitation from wave loads at design sea-states. The benefit of this is reduced uncertainties from the dynamic effects in the design phase. However, some jacket structures in deep water or soft soil-conditions may have natural periods exceeding...
