Active vibration control of a monopile offshore structure [PDF]

Journal of Structural Control, 1999
AbstractIn the Danish part of the North Sea monopile platforms with a cylindrical shaft have been used at the exploitation of marginal fields. In the paper a new principle for active vibration control of such structures is suggested. The principle is based on a control of the boundary layer flow around the cylinder of the platform, so the drag force in

An Oceanography‐Based Anticipatory Approach to Monitoring Fisheries and Fishery Resource Impacts From Offshore Wind Farms: A Perspective From the Mid‐Atlantic Bight, USA

Fisheries Oceanography, Volume 35, Issue 1, Page 5-21, January 2026.
ABSTRACT The Middle Atlantic Bight (MAB) of the eastern US differs from other offshore wind (OSW) development sites due to a unique seasonal oceanographic stratification regime. Fisheries there target migratory finfish and sedentary shellfish, the productivity and distribution of which are driven by oceanography with dynamic mesoscale features that can

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.

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

Large-scale experimental study on scour around both slender and large monopiles under irregular waves

Water Science and Engineering
Offshore wind power plays a crucial role in energy strategies. The results of traditional small-scale physical models may be unreliable when extrapolated to large field scales.

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 ...

Soil Interaction and Grout Behavior for the NREL Reference Monopile Offshore Wind Turbine

Journal of Marine Science and Engineering, 2020
Monopiles for offshore wind are the most used foundations by farm operators due to their low production costs, when compared to other bottom-fixed or floating foundations.
