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 ...

Experimental Research on the Dynamic Characteristics of Offshore Wind Turbine Model Under the Action of Highly Nonlinear Waves

南方能源建设, 2023
[Introduction] Monopile foundation is currently the most widely used support structure for offshore wind farms. For offshore wind farms in the medium water depth area such as Dafeng, Binhai and Sheyang in China, the design waves are very close to the ...

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

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.

High Strength Steel Fatigue Crack Growth Database for Offshore Renewable Energy Applications

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT High strength steels can reduce costs and carbon emissions in offshore renewable energy, but their effect on structural integrity remains unclear. In welded structures, such as support structures for offshore wind and tidal turbines, fatigue life is dominated by crack growth from flaws at weld toes.

Dynamic Performance of Monopile-Supported Wind Turbines (MWTs) under Different Operating and Ground Conditions

Energies, 2023
A monopile is the most popular foundation type for wind turbines. However, the dynamic performance of monopile-supported wind turbines under different operating and ground conditions is not fully understood.

The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

Journal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental

Rate effects for monopile foundations

, 2022
Monopile pile foundations are the most commonly used support system for offshore wind turbines in Europe. These foundations are subject to lateral loading, which is cyclic in nature, with the loading rate and load eccentricity varying with time. Under extreme conditions, such as the emergency stop of the turbine, yawing or ship impact, transient ...
