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

Monopile Implementation in Offshore Bridge

International Journal For Multidisciplinary Research
This paper presents an in-depth analysis of the implementation of monopiles in offshore and overwater bridge construction. Monopiles, cylindrical steel structures driven into the seabed or riverbed, have gained prominence as a foundation solution due to their cost-effectiveness, ease of installation, and environmental benefits.

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.

Fatigue Damage Characteristics of Offshore Wind Power Large-Diameter Monopile Structures During Driving Process

南方能源建设
[Objective] Large-diameter monopile foundations are widely used in marine engineering in China and are typically installed through penetration. Due to the impact of the pile hammer, the pile body experiences continuous impact loads during the driving ...

Dynamic Analysis of a Monopile Supported Offshore Wind Turbine [PDF]

Proceedings of the 5th International Congress on Computational Mechanics and Simulation, 2014
This paper describes the stochastic dynamic response of National Renewable Energy Laboratory 5 MW offshore fixed-based wind turbine (OWT) under various soil conditions – medium dense sand, stiff clay and layered profiles in 20 m depth of water. The aerodynamic and hydrodynamic OWT loads are derived using the force-controlled approach.

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.

MONITORING MONOPILE PENETRATION THROUGH MAGNETIC STRAY FIELD MEASUREMENTS

Proceedings of the XI International Conference on Structural Dynamics, 2020
Current methods to infer the penetration of a steel monopile during an offshore installation are rather inaccurate. Since a large number of foundation piles will be installed offshore in the coming years, a reliable technique to infer the penetration depth is vital.

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 ...

Optimization of monopile offshore wind structures [PDF]

, 2011
ABSTRACT: As industrialization is essential for large-scale offshore wind deployment, a computerized methodology to optimize the scantling of monopile steel structures has been developed using a genetic alg rithm. The objective functions of this tool are minimization of the structure weight and production costs.

Submerged Arc Welding of S355G10+M Steel: Analyzing Strength, Distortion, Residual Stresses, and Fatigue for Offshore Wind Applications

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3859-3878, September 2025.
ABSTRACT This research delves into the material performance of submerged arc‐welded S355G10 +M structural steel for offshore wind turbines, with an emphasis on strength, ductility, hardness, distortion, residual stress, and fatigue. This was done by conducting experiments and employing modeling tools combined with image analysis.
