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

Comparative Study on Wave Elevations Downstream of Monopile- and Jacket-Mounted Offshore Wind Turbines

Journal of Marine Science and Engineering
Offshore wind turbines, especially the fixed-bottom type, have been commercialized and installed in recent years. Generally, an offshore sub-structure such as a monopile or a jacket foundation is adopted to secure offshore wind turbines.

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 ...

Corrosion and Degradation of Materials in Marine Environments: Implications for Coastal and Offshore Infrastructure

Engineering Reports, Volume 8, Issue 7, July 2026.
This study presents a failure‐oriented analysis of corrosion in marine infrastructure, linking degradation mechanisms to crack initiation, fatigue propagation, and structural failure. A unified framework is proposed to connect environmental exposure, material degradation, and reliability, supporting failure prediction, inspection planning, and life ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces
