Comparative Study on Wave Elevations Downstream of Monopile- and Jacket-Mounted Offshore Wind Turbines

Journal of Marine Science and Engineering
Offshore wind turbines, especially the fixed-bottom type, have been commercialized and installed in recent years. Generally, an offshore sub-structure such as a monopile or a jacket foundation is adopted to secure offshore wind turbines.

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.

PISA: Recent Developments in Offshore Wind Turbine Monopile Design

, 2018
This paper provides a brief overview of the Pile Soil Analysis (PISA) project, recently completed in the UK. The research was aimed at developing new design methods for laterally loaded monopile foundations, such as those supporting offshore wind turbine structures.
