Field Performance of Scour Protection around Offshore Monopiles [PDF]

Scour and Erosion, 2010
Offshore Windpark Egmond aan Zee was installed in 2006 and is the first Dutch offshore windpark. To guarantee a fixed seabed level, dynamic scour protections were installed at all 36 monopiles. Since installation 251 multibeam surveys were executed to investigate the as-built stages and yearly performance of the dynamic scour protection.

A Structured Techno‐Economic and Socio‐Regulatory Comparison of Onshore, Fixed‐Bottom Offshore, and Floating Offshore Wind Energy Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Onshore, fixed‐bottom offshore, and floating offshore wind turbines (FOWTs) represent distinct technological pathways for large‐scale wind energy deployment, yet comparative assessments often emphasize descriptive characteristics rather than quantified performance trade‐offs.

Small-displacement behavior of offshore wind power monopiles subjected to static lateral loading

Yantu gongcheng xuebao
The centrifuge tests and numerical simulations are carried out to explore the small-displacement behavior of 9 m-diameter offshore wind power large-scale monopiles with various embedment depths. The results show that as the embedment depth increases, the

Divergent Patterns in Wind Power Project Cost Overruns: How Scale Matters and Determinants of Construction Risk

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT This study analyzes cost overruns in 80 wind power projects, focusing on the impact of configuration types and their interaction effects with other project characteristics. Using multiple regression analyses, including interaction terms and segmented regression, we investigate four key aspects of cost overruns in wind power projects. First, we

Effects of an array of widely separated vertical cylinders on time-averaged properties of progressive monochromatic waves

RBRH, 2020
The design of monopile foundations for offshore wind farms, the estimate of wave loads, and the effect of the structures on the environment usually consider one single vertical cylinder.

Dynamic Performance of Advanced Composite Towers in Offshore Wind Farms: Experimental and Numerical Investigation

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT Conventional steel towers face challenges such as insufficient stiffness and structural instability, making them increasingly unsuitable for supporting large multi‐megawatt wind turbines. This study investigates the dynamic performance of concrete‐filled double‐skin steel tubular (CFDST) wind turbine towers as a novel structural member ...

Closed form solution of Eigen frequency of monopile supported offshore wind turbines in deeper waters incorporating stiffness of substructure and SSI [PDF]

, 2016
Offshore wind turbines (OWTs) are dynamically loaded structures and therefore the estimation of the natural frequency is an important design calculation to avoid resonance and resonance related effects (such as fatigue).

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
