Challenges

Proactive damage monitoring: Slash maintenance costs by catching issues early

Wind turbines are susceptible to various types of damage, which can lead to significant maintenance costs. Not only obvious damage, such as a split blade tip, requires attention. Even damage, such as erosion, cracks, or delamination, can escalate maintenance expenses. Therefore, monitoring surface damage is crucial to identify which turbines are affected, observe existing damage, and detect potential issues before they lead to major failures and costly repairs.

Challenges

High repair costs

Not all damage necessitates immediate action, but undetected severe damage can lead to significant consequences. These may result in high repair costs or lead to loss of earnings amounting to several hundred thousand USD.

Challenges

Unplanned and unnecessary downtime

Unscheduled downtimes directly impact revenue generation, leading to potential financial losses.

Challenges

Limited budget for operational expenditure

Without a blade damage monitoring system, identifying which turbines are damaged can be challenging and costly. Visual inspections are needed to determine which turbines require attention, consuming valuable time and resources. By reducing unscheduled maintenance and providing immediate notifications with early damage detection, you can prioritize your spending and manage your limited operational budget more effectively.

Features

What our :SURFACE HEALTH offers you

Wind turbine damage can occur anytime, even right after an inspection. Without continuous monitoring, you’re operating blindly, risking undetected damage that leads to high costs, extensive maintenance, and reduced performance.

 

Our :SURFACE HEALTH solution provides continuous rotor blade surface monitoring, detecting damage early to prevent costly disruptions. It also tracks existing issues, alerting you if they worsen. This proactive approach helps you prioritize turbines needing attention, ensuring optimal performance and minimizing unexpected expenses. Trust :SURFACE HEALTH to safeguard your operations with continuous monitoring and timely alerts.

Early detection for optimized repair

Our surface damage detection solution uses acoustic emissions caused by airflow over damage and disturbances to monitor the overall condition and look for trends/emergencies in the surface condition. This enables early damage detection, timely repairs and prevents small problems from developing into critical failures.

Reduce unplanned downtime

Not only does our system allow you to proactively address root causes, it also allows you to prioritize repairs and shutdowns for visual inspections. This reduces interruptions and ensures continuous operation and increased annual energy production (AEP).
