Comparative Concept Design Study of Laterally Loaded Monopiles

, 2019
Offshore wind turbine generators (WTG) are commonly founded on single large diameter piles, named monopiles. These monopiles are subjected to significant lateral loads and thereby sizeable overturning bending moments mainly due to action of wind and wave

Monopile Implementation in Offshore Bridge

International Journal For Multidisciplinary Research
This paper presents an in-depth analysis of the implementation of monopiles in offshore and overwater bridge construction. Monopiles, cylindrical steel structures driven into the seabed or riverbed, have gained prominence as a foundation solution due to their cost-effectiveness, ease of installation, and environmental benefits.

Numerical study of hot‐spot stresses in single sided welded T‐Joints for fatigue assessment of offshore foundations

ce/papers, Volume 9, Issue 2-3, Page 2820-2825, September 2026.
Abstract The growing expansion of offshore wind energy requires more accurate assessment strategies for fatigue life of welded joints. T‐Joints are a frequently structural detail in monopile‐based offshore foundations, for example at boat landings and secondary steel attachments. During global tower bending due to wind loading or wave impact, secondary

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, Volume 6, Issue 3, Page 407-424, September 2026.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...
