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

Optimization of monopile offshore wind structures [PDF]
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
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.

The design of an offshore wind turbine (OWT) founded on a monopile foundation is principally based on dimensioning criteria related to its fundamental frequencies. These frequencies must remain outside the excitation frequencies to avoid resonance.

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

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 ...

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