Seismic Response Mechanism and Soil–Structure Interaction of Monopile Offshore Wind Turbines Under Flat and Near‐Sloping Seabed Scenarios

Shock and Vibration, Volume 2026, Issue 1, 2026.
Monopile foundations are widely used in fixed‐bottom offshore wind turbines (OWTs), and their seismic response is strongly affected by pile–soil–structure interaction. Most existing studies have focused on OWTs located on flat and idealized seabeds, whereas the influence of near‐slope seabed topography has received relatively limited experimental ...

A Safety‐Aware Framework for Offshore Wind Turbine Maintenance

Wind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT In this paper, we suggest a framework for determining the best operation and maintenance strategies for offshore wind turbines. The framework takes into account both quantitative and qualitative data gathered from the wind turbines. The proposed framework consists of a simulation‐optimization approach for designing, planning, and scheduling ...

Least‐Squares Projected Models for Non‐Intrusive Affinization of Reduced Basis Methods

International Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.
ABSTRACT Reduced‐basis methods (RBMs) constitute a promising technique for delivering numerical solutions of parameterized PDEs in real time and with reasonable accuracy. The most significant drawback of RBMs is the requirement of parametric affinity, a condition that only very trivial problems satisfy.
