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

open access: yesInternational 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.

State‐of‐the‐Art Review of Vibration‐Based Health Monitoring of Piles

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Vibration‐based health monitoring (VHM) has emerged as a promising technique for assessing the integrity of deep foundations by interpreting variations in dynamic response governed by soil–pile interaction. This review presents the theoretical background of foundation failure mechanisms, sensing technologies, and numerical approaches that underpin VHM ...

The large scale impact of offshore wind farm structures on pelagic primary productivity in the southern North Sea

open access: yes, 2018
The increasing demand for renewable energy is projected to result in a 40-fold increase in offshore wind electricity in the European Union by 2030. Despite a great number of local impact studies for selected marine populations, the regional ecosystem ...

Optimization of monopile offshore wind structures [PDF]

open access: yes, 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.

Modal Identification Method of Offshore Wind Turbine Tower Based on SSI and FSDPC

open access: yesShock and Vibration, Volume 2026, Issue 1, 2026.
The structural health monitoring of offshore wind turbine towers is critical for ensuring their operational integrity. The condition of the tower structure is characterized by its modal parameters, which serve as effective health indicators. These parameters are identified through modal identification techniques.

Diameter-dependent analytical p–y curves for response analysis of monopiles in sand

open access: yesInternational Journal of Geo-Engineering
Large-diameter monopiles are extensively used to support onshore bridges, port terminals, and offshore wind farms due to their high load-bearing capacity, low settlement and excellent seismic performance.

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

open access: yesWind 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

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

open access: yesWind 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 ...
