As renewable energy continues its rapid growth, safeguarding the integrity of wind energy infrastructure emerges as a critical business priority. At New York Energy Week 2025, Lisa Czyszczewski, Vice President of Growth Strategy, and Dr. Ryan Marks, Head of Monitoring at MISTRAS Group, discuss practical approaches to managing asset integrity in wind energy, emphasizing how proactive monitoring strategies protect substantial investments for decades of safe, reliable operation.
Why Asset Integrity is Critical for Renewables
Lisa Czyszczewski sets the stage by describing the dramatic expansion of wind energy assets across the United States. Drawing on forecasts from the U.S. Department of Energy, she highlights the ongoing shift from predominantly land-based wind farms to increasingly ambitious offshore installations. These offshore assets face harsher environments and present unique maintenance challenges. Turbines initially intended to operate for roughly 20 years must now safely and efficiently function for 35 years or more, underscoring the importance of comprehensive asset integrity strategies.
Distinctive Challenges of Offshore Wind Operations
Dr. Ryan Marks elaborates on the unique complexities associated with offshore wind turbines. While larger offshore turbines capture greater wind energy, they must withstand exposure to corrosive seawater, strong ocean currents, wave impacts, and seabed erosion—factors far less problematic for onshore turbines. Additionally, their remote locations significantly complicate maintenance efforts, increasing costs and operational risk.
Marks emphasizes that the underwater foundations supporting offshore turbines are particularly crucial because replacing these structures mid-life is not realistically feasible. As such, ensuring the health of these underwater foundations is essential for long-term operational success.
Leveraging Data to Optimize Turbine Life
Marks stresses that effective asset maintenance strategies hinge on real-time data and insights. Monitoring turbine components continuously allows operators to optimize uptime, efficiently schedule maintenance activities, and proactively address potential problems before they escalate into costly repairs.
A growing industry trend involves integrating monitoring systems from the very start of turbine construction rather than retrofitting them later. Operators recognize that upfront investment in monitoring delivers substantial long-term financial benefits and enhanced reliability. Data-driven strategies help operators respond quickly if sensors detect early indications of damage—adjusting workloads or planning preventive maintenance to mitigate risks.
Innovative Monitoring Technologies in Practice
MISTRAS Group deploys a variety of innovative monitoring solutions to address the unique needs of wind energy assets:
Acoustic Emission Monitoring for Turbine Blades
Acoustic emission (AE) monitoring is a cornerstone technology for MISTRAS, capable of detecting subtle, high-frequency acoustic signals that indicate early-stage structural damage. Marks provides a compelling real-world example: an AE sensor placed in the turbine hub detects anomalies in blade acoustics, enabling operators to identify and repair a significant blade defect long before the problem worsens. By catching issues early, this method significantly reduces the risk of catastrophic blade failures.
Advanced Monitoring of Offshore Foundations
Marks describes how MISTRAS deploys AE technology for critical offshore foundations, referencing a case study at the Greater Gabbard offshore wind farm near Norfolk, UK. Here, sensors placed inside monopile foundations continuously monitor for signs of cracks or structural deterioration. These sensors precisely pinpoint the location of issues, immediately alerting operators to potential problems. Real-time monitoring substantially increases the structural safety of offshore installations, ensuring continued operational integrity.
Strategic and Cost-Effective Foundation Monitoring
MISTRAS currently collaborates with strategic partners like Arup on projects off the coast of Scotland, installing monitoring systems on a carefully chosen subset of wind turbine foundations. By monitoring a representative selection of turbines in various locations—some in deeper water, others in shallower sites—operators can extrapolate data to gauge the overall health of the entire wind farm. This strategic approach provides comprehensive insights without incurring unnecessary costs from monitoring every turbine individually.
Turning Complex Data into Clear Decisions
Czyszczewski and Marks underscore the importance of translating vast volumes of complex sensor data into clear, actionable insights. Operators prefer straightforward dashboards using intuitive indicators (e.g., green, yellow, red) that highlight potential issues at a glance. This clarity enables rapid decision-making about maintenance priorities and operational adjustments, significantly improving the efficiency and cost-effectiveness of maintenance scheduling.
Through optimized maintenance scheduling driven by accurate, real-time monitoring data, operators reduce unnecessary inspections and avoid unplanned downtime. This proactive approach considerably lowers operating costs and enhances profitability.
Addressing Cybersecurity in Asset Monitoring
Recognizing the growing cybersecurity risks in operational technology, Marks highlights that integrating digital monitoring systems into critical infrastructure must not introduce security vulnerabilities. MISTRAS addresses these concerns by developing secure solutions where data is securely "pushed" out from turbines, preventing external systems from directly accessing operational controls. These rigorous cybersecurity measures ensure reliable, uninterrupted operation of turbines powering essential energy grids.
Demonstrated Value through Real-World Experiences
Marks and Czyszczewski emphasize how early investment in proactive monitoring solutions clearly pays off. While implementing monitoring systems involves upfront costs, operators typically recoup these expenses quickly through reduced operational risks, fewer emergency repairs, and extended asset life.
Marks further demonstrates the value by detailing successful deployments in both turbine blades and offshore foundations. In each instance, timely detection of developing issues allowed operators to intervene early, avoiding costly disruptions and extending the service life of critical renewable assets.
Protecting Long-Term Renewable Investments
Throughout their presentation at New York Energy Week 2025, Czyszczewski and Marks illustrate that comprehensive asset integrity monitoring is essential for the long-term success of renewable energy investments. Proactive, technology-driven monitoring strategies ensure turbines remain safe, reliable, and operationally efficient for decades. In a rapidly expanding renewable energy sector, strategic investment in advanced monitoring solutions not only protects infrastructure but also significantly enhances economic returns and operational reliability.
In short, the future of renewable energy depends heavily on maintaining the integrity of critical infrastructure. By proactively investing in advanced monitoring systems today, operators ensure a robust and resilient renewable energy landscape for many years to come.
