Prediction of the Behaviour of Monopiles Under Drained Two‐Way Cyclic Lateral Loading in Sand

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 16, Page 3696-3712, November 2025.
ABSTRACT The monopile is considered as one of the preferred geotechnical foundations for the offshore wind energy converter; therefore, its cyclic behaviour is one of the major concerns in the design. In the current design approaches, the prediction of two‐way cyclic behaviour mainly depends on empirical equations, in which the specific site conditions

Effect of ordering of cyclic loading sequences on the short-term performance of offshore monopiles in an overconsolidated clay

Applied Ocean Research
Wind and wave actions that vary in amplitude, frequency and direction cause irregular cyclic loading on monopiles supporting offshore wind turbines (OWTs), resulting in cumulative deformation.

Creating a Real‐Time Capable Surrogate Model of a Wind Turbine Using Machine Learning

Wind Energy, Volume 28, Issue 11, November 2025.
ABSTRACT Multibody simulation (MBS) is an established method for modeling wind turbines for purposes such as load calculation. While capable of modeling wind turbines at high levels of detail, large MBS models can be computationally expensive. This makes deployment for real‐time critical use cases like digital twins difficult.

Numerical analysis of offshore monopile foundations in layered clay

Applied Ocean Research
Monopiles are often embedded in layered soil profiles, where stratification significantly influences their lateral load response. However, much of the existing literature and proposed methodologies predominately focus on uniform soil profiles which is ...

Self-weight Penetration Prediction Methods for Large Diameter Monopiles in Offshore Wind Farm

南方能源建设, 2020
[Introduction] Large diameter monopile is the most common used foundation in offshore wind projects. The Self Weight Penetration (SWP) usually takes up a large component of total penetration.

Assessment of the Distribution of the Gaps Between Ring Flange Connections in Offshore Wind Turbines

ce/papers, Volume 8, Issue 3-4, Page 289-297, September 2025.
Abstract Ring flange connections are commonly used to connect the tower of offshore wind turbines with monopile foundations. Studs in these ring flange connections are sensitive to fatigue damage accumulation, which is aggravated by gaps between the flanges. Such gaps are inevitable because of imperfections (out‐of‐flatness) of the flanges.

Cost Development and Cost Drivers in UK Offshore Wind Farms

Wind Energy, Volume 28, Issue 9, September 2025.
ABSTRACT The offshore wind industry faces challenges of impairments, project abandonment, and no bids in auction rounds, following several years of cost increases and project delays. Both industry and government rely on cost reductions. Companies struggle with low business‐economic profitability, and taxpayers require a justification for government ...

Did the pile driving during the construction of the Offshore Wind Farm Egmond aan Zee, the Netherlands, impact porpoises? [PDF]

The Dutch consortium "NoordzeeWind" has built the first offshore wind farm in Dutch North Sea waters, known as "Offshore Wind farm Egmond aan Zee" (OWEZ) Part of the construction works consisted of driving 36 monopiles into the sea floor, during April ...
