Multi-hazard response analysis of a 5MW offshore wind turbine [PDF]
, 2017 Wind energy has already dominant role on the scene of the clean energy production. Well-promising markets, like China, India, Korea and Latin America are the fields of expansion for new wind turbines mainly installed in offshore environment, where wind ...

Monopiles subjected to uni- and multi-lateral cyclic loading [PDF]
, 2017 Offshore wind turbines are subjected to significant environmental loads from a combination of current, wind and wave action. Under such conditions, the directions of these environmental loads vary over the service life of the structure and therefore the ...

Evaluation of sand p–y curves by predicting both monopile lateral response and OWT natural frequency
Studia Geotechnica et Mechanica, 2022 Extending the use of the p–y curves included in the regulation codes API and DNV to design large-diameter monopiles supporting offshore wind turbines (OWTs) was unsuccessful as it resulted in an inaccurate estimation of the monopile behavior.

Numerical Analysis of Hydrodynamic Characteristics of Monopile-type OWT Under Breaking Wave
南方能源建设, 2020 [Introduction] The design waves of Nanhui, Donghai and Dafeng offshore wind farms in China are all in medium water depth and very close to the breaking limit of waves, it is necessary to explore the dynamic response of monopile type offshore wind turbine

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).

Load reduction of a monopile wind turbine tower using optimal tuned mass dampers [PDF]
, 2017 We investigate to apply tuned mass dampers (TMDs) (one in the fore–aft direction, one in the side– side direction) to suppress the vibration of a monopile wind turbine tower.

Drainage conditions around monopiles in sand [PDF]
Applied Ocean Research, 2019 Abstract Large diameter monopiles are typical foundation solutions for offshore wind turbines. In design of the monopile foundations in sand, it is necessary to understand the drainage conditions of the foundation soil under the design loading conditions as the soil performance (strength and stiffness) is highly dependent on the drainage conditions ...

Applied Sciences, 2023 Offshore Wind Turbines (OWT) with increasingly higher energy output are being developed to meet energy demands, posing greater challenges for their foundation design. Several foundation types are used to support these turbines, with monopiles (MPs) accounting for 80% of the installed capacity.
