# Structural Health monitoring for wind turbine blades. TWI has completed research into enhanced condition monitoring systems for wind turbine blades that will decrease maintenance costs and increase installation reliability, allowing the development of more remote offshore wind farms and thus reducing pressure for onshore installations. Operation and maintenance costs constitute a sizeable share of the total annual costs of a wind turbine. For a new machine, these costs might easily have an average share over the lifetime of the turbine of more than 30% of the total cost per kWh produced. The acoustic emission (AE) technique for structural health monitoring (SHM) is an active area of research primarily due to the requirement for complex signal processing to extract and identify the signals of interest from a noisy background. The main purpose of this study was to investigate the feasibility of in-service monitoring of the structural health of blades using AE.

## An advanced structural health monitoring IoT platform for offshore wind turbine blades. This paper presents a novel Internet of Things (IoT) platform for structural health monitoring (SHM) of the offshore wind turbine's key components, the wind turbine blades, taking the design and manufacturing of turbine blades into account. This research focuses on developing a comprehensive, real-time monitoring system that utilises advanced sensor networks and edge computing, empowering advanced predictive algorithms to strengthen in-time maintenance of turbine blades, improving operational efficiency and reducing maintenance cost. Key words: Offshore wind turbines / IoT platform / structural health monitoring / blade monitoring / QRS sensor / cloud database / wind energy / renewable energy. In this sense, the turbine blades are critical components of large-scale offshore wind turbines. This paper presents a novel IoT platform targeting structural health monitoring (SHM) of offshore wind turbine blades.

Online structural health monitoring (OSHM) and condition-based maintenance (CBM) of wind turbine blades has the potential to reduce O&M costs and hence reduce the overall cost of wind energy. Further benefits include reducing maintenance costs by avoiding failures and detecting blade defects earlier, than would otherwise be possible. The CBM cases of LCC examine the costs over the life of a wind turbine blade including the condition monitoring system, repair costs, and blade replacement costs. Figure 3 (Left) & Figure 4 (Right) – Distribution of visual inspection and online condition monitoring cost differential – Worst Case (3) Best Case (4) CONCLUSIONS Online condition monitoring has the potential to reduce the O&M costs associated with wind turbine blades by detecting defects before they propagate into larger defects and eventual failures.
