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

Numerical analysis of offshore monopile foundations in layered clay

Applied Ocean Research
Monopiles are often embedded in layered soil profiles, where stratification significantly influences their lateral load response. However, much of the existing literature and proposed methodologies predominately focus on uniform soil profiles which is ...

Drag and Lift Forces on Bed Sediments in Open‐Channel Flow Through Boulders at Various Froude Numbers

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 ...

Early detection and location of unexpected events in buried pipelines under unseen conditions using the two‐stream global fusion classifier model

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 ...
