For critical oil and gas assets, sometimes a visual inspection only tells half the story. Confirming physical measurements such as Non-Destructive Testing (NDT) and Ultrasonic Thickness (UT) adds crucial insights into the condition of storage tanks, pipelines and other key energy assets.
Historically, collecting this data has meant high-risk, expensive, and time-consuming access via rope or Elevated Work Platforms (EWP). This can result in data points that often get buried in static PDF reports.
This is the gap Trendspek’s Structural Lifecycle Management (SLM) platform is built to close.
By integrating advanced aerial NDT data directly into your millimetre-accurate 3D Reality Twins, we move beyond simple visual assessment to enable truly defensible, data-driven decisions.
The New Reality: Physical Data Meets the Digital Twin
The rise of specialised aerial robotics, such as Voliro, is transforming how physical measurements are gathered. These advanced Unmanned Aerial Vehicles (UAVs) are engineered to perform accurate, contact-based NDT on complex structural geometries at height, eliminating the need for hazardous human access.
They can be fitted with NDT probes like Ultrasonic Transducers (UT) and maintain stable contact on surfaces at any angle, including vertical or overhead areas.
The Voliro T is groundbreaking aerial robotic platform specifically engineered to perform advanced, contact-based Non-Destructive Testing (NDT) on complex industrial assets. Using an open, modular payload platform, this allows it to integrate various NDT sensors for different inspection needs.
This is transforming routine inspections across large oil and gas sites by enabling physical contact with structures from the air — a capability that traditional, visual-only drones lack.
Non-Destructive Testing (NDT) Capabilities
| Voliro T Core Technology | Function & Detail |
|---|---|
| Ultrasonic Transducer (UT) | Measures wall thickness and detects subsurface defects like cracks or corrosion. The UT probe can include Echo-to-Echo and Pulsed Echo test modes. A high-temperature UT probe can operate on assets up to 260∘C (500∘F), eliminating the need for cooling or shutdown during inspection. |
| Electromagnetic Acoustic Transducer (EMAT) | Measures material thickness and is ideal for rough, corroded, or dirty surfaces as it can operate without a couplant (gel/oil). |
| Dry Film Thickness (DFT) | Measures the thickness of protective coatings, such as epoxy or zinc. |
| Pulsed Eddy Current (PEC) | Designed for detecting corrosion under insulation (CUI), coatings, and fireproofing without requiring their removal. |
| Lightning Protection System (LPS) Tester | Used for measuring the resistance of receptors on assets like wind turbines. |
By reducing the need for scaffolding or heavy machinery, this integrated approach minimises operational disruptions, enhances worker safety, and shortens project timeframes.
This provides a safer, faster, and more comprehensive approach to inspections in hard-to-access locations.
Combining UAV-Collected NDT with 3D Context in Trendspek
The real breakthrough happens when this geolocated NDT data is brought into a 3D reality twin platform like Trendspek.
Trendspek converts NDT, photogrammetry and spatial data into interactive 3D replicas of built assets, with millmetre detail.
By reducing the need for scaffolding or heavy machinery, this integrated approach minimises operational disruptions, enhances worker safety, and shortens project timeframes.
By combining the two, this enables:
Physical Data in Context
Contact-based data, such as A-scan data or ultrasonic thickness measurements, is now mapped directly onto the exact point on the high-fidelity 3D model. No more guessing where a PDF data point corresponds on the physical asset.
Layered Insights
You can overlay this physical data with your visual reality capture, thermal, and historical inspection layers in a collaborative, browser-based environment. This creates a centralised data source for every stakeholder—from the facilities manager to the maintenance planner.
Defensible Planning
By visualising physical measurements in the reality twin, you gain confidence in tracking degradation and making risk-based decisions. This enables you to justify CAPEX allocation with concrete evidence, leading with preventative maintenance rather than urgent, reactive repairs.
