High-efficiency tower weld inspections:
How Kratos Optimizes Turbine Life-Extension
- May 26, 2026
The structural integrity of the steel tower, specifically its thousands of meters of weld seams, is the literal foundation of asset longevity. When dats is needed for decisions to confidently extend operation lifespan, KRATOS steps in.
Moving Beyond Theoretical Models to Physical Certainty
Traditionally, life-extension strategies have heavily relied on theoretical engineering models and historical weather data. While useful, these models simly can´t account for the unique, real-world micro-stresses that each individual turbine faces over the years.
KRATOS captures high-resolution data on material fatigue, sub-surface cracks, structural anomalies and more. All while being controlled from the ground, giving technicians the ability to inspect tower welds in a quicker and safer way than by traditional platform based inspections.
Advanced Sub-Surface Inspection: The Technology Inside
Time-of-Flight Diffraction (TOFD): A computerized data aquisition system that records variations in the transit time of diffracted waves. TOFD is highly efficient at detecting vertical defecs, such as "lack of fusion" where the welded joints aren´t perfectly bonded.
Phased Array Ultrasonic Testing (PAUT): Utilizing a pulse-echo methodology, this probe system measures transit time and sound attenuation to accurately determine the exact presence, depth and dimensions of internal material flaws.
KRATOS vs. Traditional Inspection Methods
Traditional UT inspection methods rely heavily on rope access technicians or complex scaffolding and platforms. These methods are a burden on operational metrics, requiring extensive mobilization windows, large field crews, and prolonged periods of turbine standstill.
Drastic Reduction in Downtime: KRATOS moves rapidly and performs continuous scanning along the weld paths. Furthermore, set up requires a fraction of the time and effort typically dedicated to other methods. These two features alone drastically reduce the revenue-loss window associated with taking a turbine offline.
Minimized Project Footprint & Logistics: Apart from time, manual inspection setups also involve massive equipment footprints, heavy vehicle transport, and large teams. With a robot, a field technician, and a UT expert, KRATOS is ready to deploy, allowing for the project to be focused more on results, and less on logisitcs.
Uncompromised Safety Profiles: By utilizing ground-controlled robotics, field personnel are able to avoid working entire days at height. Gone are the days that technicians need to climb towers in order to obtain high-level results.
