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 ...

An investigation into the effect of scour on the natural frequency of an offshore wind turbine [PDF]
, 2015 Rapid expansion of the offshore wind industry has stimulated a renewed interest in the behaviour of offshore piles. There is widespread acceptance in practice that pile design methods developed for the offshore oil and gas industry may not be appropriate

Journal of Marine Science and Engineering, 2023 Offshore wind power is a new trend in renewable energy development. However, during the operation of offshore wind turbines, the rock-socketed monopile foundation is subjected to long-term cyclic loads, which will cause the seawater to erode the rock ...

Modeling Lifetime Performance of Monopile Foundations for Offshore Wind Applications
Journal of Geotechnical and Geoenvironmental Engineering, 2023 This paper explores the application of a numerical method for modeling pseudorandom cyclic loading, at very large cycle numbers, to the design of offshore wind turbine foundations. The work expands the development of a novel constitutive modeling framework, the hyper-plastic accelerated ratcheting model (HARM), for which the key constitutive equations ...

An assessment of pile driveability analyses for monopile foundations
, 2022 Several methodologies to predict the static soil resistance to driving (SRD) available in the literature have found wide use in the offshore industry over the last decades. These range from simple methods that require few soil strength parameters to more advanced semi-empirical methods that correlate the driving resistance to cone penetration test ...
