Terra Inspectioneering executes ultrasonic thickness (UT) measurements using drones. With the Terra UT drone it is possible to execute certified steel thickness measurements at hard to reach places at height, such as storage tank walls, roofs and rafters or boiler tubes.
The UT drone is Terra's proprietary development and is based on patented technology that enables the drone to firmly and precisely clean the spot to be measured and press the UT probe against the surface. The drone has been specially developed for indoor use in industrial confined spaces and can be controlled in the presence of steel and concrete.
Pro/con
Reduced HSE risk by mitigating work at height and confined space entry
Eliminates scaffolding and rope access costs
Fast deployment, automatic UT data cloud storage
Reduced downtime of assets
Cleaning brush for optimal surface preparation
Detailed monitoring of UT A-Graph live on screen
Support for tank shell, roof, floor and rafters
If surface is too heavily corroded, UT measurements are not possible
