Summary

Energy infrastructure, encompassing offshore engineering structures, power system equipment, photovoltaic support structures, and other critical energy facilities, provides fundamental support for global energy supply. Serving in harsh environments with complex dynamic loads, such structures commonly suffer from performance degradation, damage accumulation, and potential safety hazards, which makes structural monitoring, integrity assessment, and safe operation indispensable.


This special issue places a strong emphasis on the development, optimization, and engineering application of novel sensing technologies and high-performance sensors for structural deformation and condition monitoring. It also covers risk-based inspection (RBI) in practical engineering scenarios, wind-induced vibration monitoring, and bolt looseness detection for structural components, structural damage identification and integrity assessment, as well as safety operation and maintenance strategies for energy infrastructure. We welcome high-quality original research and engineering applications that integrate technological innovation with on-site implementation, aiming to promote the progress of structural safety and reliability technologies for energy infrastructure.

    A Novel Smart Vision-Based Sensing System for Structural Health Monitoring: Robust Angle Measurement of Offshore Rotating Machinery with Data-Driven Calibration

    Qingmin Hou, Guanghua Xiao, Qiang Liu, Chunhui Su, Ting Yan, Yafen Sun, Peng Zhang

    Abstract To address the critical need for reliable condition monitoring of rotating components (e.g., crane slewing bearings, thrusters) in harsh marine environments characterized by strong electromagnetic interference, salt spray, and persistent vibration, this paper presents a novel smart sensing system for high-precision rotation angle measurement. The proposed intelligent inspection system employs a vision-based principle: a laser spot, projected from a turntable synchronized with the measured shaft, forms a circular trajectory on a fixed Complementary Metal-Oxide-Semiconductor (CMOS) image sensor. A robust machine vision algorithm, integrating an improved Canny-Kirsch operator and a least-squares ellipse fitting method, achieves sub-pixel… More >

    Reflective Fiber Optic Angle Sensor for Monitoring the Rotation State of Monopolar Photovoltaic Tracking Mounts

    Qingmin Hou, Guanghua Xiao, Tongtong Dai
    Structural Durability & Health Monitoring, Vol.20, No.5, 2026, DOI:10.32604/sdhm.2026.087157
    (This article belongs to the Special Issue: Monitoring, Assessment and Safe Operation of Energy Infrastructure)
    Abstract To address the issue of angular deviation in inclined single-axis photovoltaic tracking mounts during long-term operation-caused by wind disturbances, mechanical transmission gaps, installation inaccuracies, and environmental factors-a angle sensor based on reflective fiber-optic ranging principles has been developed for monitoring the rotation angle of the main shaft. This sensor employs a structural conversion approach of “using straight lines to replace curves”, transforming the shaft’s rotational angle into linear displacement of a mirror via a gear-rack mechanism, and generating corresponding output voltage signals through variations in reflected light intensity to measure rotation angles. Due to factors… More >
