Wave Loads on Monopile Structures

, 2017
This article compares different approaches to determine the design forces and moments for the ultimate limit state for monopile structures for offshore wind turbines. The principles of the different approaches are explained. Four different methods, i.e.

Hydrodynamic Characteristic Around the Riprap Protection of Monopile Wind Power Foundation with Scour Pit During Scour

Energies
Riprap protection is widely used in offshore wind power foundations. The boundary of riprap will change and affect the hydrodynamics around the foundation during scour.

Structural Load Optimization of 15 MW Offshore Wind Turbine Using LHS-Based Design Space

Journal of Marine Science and Engineering
The structural integrity of next-generation offshore wind turbines is highly sensitive to inflow variability, yet current standards often simplify wind conditions without capturing their combined effects on dynamic loads. To address this, we analyzed the

Comparison of S-N Curves from International Fatigue Design Standards for a Better Understanding of the Long-Term Operation of Offshore Wind Turbine Welded Foundations

Wind
Fatigue poses significant challenges for the structural integrity of monopiles, the most common type of foundation for offshore wind turbines. These structures are usually manufactured by rolling and welding together large steel plates.

Monopile response to scour and scour protection

, 2020
Scour of seabed sediments can occur around offshore structures, the resultant reduction in strength and stiffness of the structure’s foundations presents operational challenges for monopile-supported offshore wind turbine structures. Turbines are at risk of reduced operation or even premature decommissioning if scour causes the natural frequency of a ...
