Fatigue crack growth rates for offshore wind monopile weldments in air and seawater: SLIC inter-laboratory test results [PDF]

, 2016
The majority of fatigue crack growth (FCG) data sets available on steels in air and seawater environments are several decades old and may not be appropriate for structural integrity assessment of offshore wind turbine foundations, which are fabricated ...

Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

Journal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Soil–Anchor Interaction Effects on Dominant Frequencies in Offshore Wind Turbines Supported by Tension Leg Platforms

Wind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT This study presents an experimental investigation into the influence of anchor–soil interaction on the dynamic behaviour of tension leg platform (TLP)–type floating wind turbines. A 1/100 scale model of the NREL 5‐MW reference wind turbine was fabricated using a 3D printer, with scaling parameters determined based on Froude scaling laws to ...
