FBG Sensing Technology for the SHM of Offshore Wind Farms
Offshore wind farms have been increasingly popular as a sustainable source of energy. However, they also face a range of challenges such as harsh environmental conditions and high maintenance costs. Therefore, it is crucial to ensure the structural health of offshore wind turbines to avoid accidents and maintain their efficiency. Fiber grating sensing technology has emerged as a powerful solution for structural health monitoring of offshore wind farms. In this article, we will discuss the problems that fiber grating sensing technology can solve, and how Beijing Dacheng Yongsheng Technology Co., Ltd.(short for DCYS ) can support the structural health monitoring of offshore wind farms in the marine industry.
Fiber Bragg Grating Sensing Principle：
Fiber Bragg gratings (FBGs) are periodic structures that are inscribed in the core of an optical fiber. These structures reflect a specific wavelength of light that is determined by the periodicity of the grating. When the grating is subjected to mechanical or thermal strain, the reflected wavelength changes in a predictable manner. By monitoring the reflected wavelength, changes in strain, temperature, and other parameters can be detected. FBG sensors can be used to monitor a wide range of parameters, including strain, stress, temperature, and vibration.

Demand Analysis for SHM of Offshore Wind Turbines:
Offshore wind turbines are subjected to harsh environmental conditions such as high wind speeds, saltwater corrosion, and extreme temperatures. These factors can cause damage to the turbines, leading to reduced efficiency, increased maintenance costs, and potential accidents. Therefore, it is essential to monitor the structural health of offshore wind turbines to identify any issues before they become critical.
Why SHM of Offshore Wind Turbines is Needed:
Structural health monitoring (SHM) of offshore wind turbines is necessary to ensure their long-term structural integrity, reliability, and safety. SHM helps to identify any damage, fatigue, or degradation that may occur over time due to environmental conditions and operational stress. This information can be used to develop maintenance plans and optimize turbine performance.
Difficulties in SHM of Offshore Wind Turbines in the Marine Industry:
The harsh marine environment poses several challenges for structural health monitoring of offshore wind turbines. The cost and logistical challenges associated with installing and maintaining monitoring systems in the offshore environment can be significant. Additionally, the high level of noise and vibration associated with wind turbines can make it challenging to detect small changes in their structural behavior.
