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.

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 ...

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.

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.

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.Abstract The Froude number (Fr) is an important parameter that affects turbulence structures, bedload transport, and bedforms in mountain rivers. In a prior study by Liu et al. (2024, https://doi.org/10.1063/5.0222673), turbulence structures in open channel flow through a boulder array placed on seven layers of spheres (comprising the channel bed ...

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 21, Page 3295-3315, 29 August 2025.Abstract Failure of buried pipelines can result in serious impacts, such as explosions, environmental contamination, and economic losses. Early detection and location of unexpected events is crucial to prevent such events. However, conventional monitoring methods exhibit limited generalization performance under varying environmental and operational ...
