The solution for automated remote Ultrasonic & Phased Array inspection on pipes & drums. Whether you are looking at corrosion mapping or weld inspection – with the modular FAST UT you have a modular inspection system.

corrosion mapping

Due to its modular design the FAST platform can be adapted to new applications quickly and easily. The modular scan axis (Y-axis) allows for raster scans, combined with Ultrasonic probes the robot delivers high quality corrosion maps.

weld inspection

Equipped with the weld following module the robot turns into a fully automated weld scanner. The Inspection Robotics probe holder can handle Phased Array and/or TOFD probes for the weld inspection.

high precision & repeatability

Automated driving combined with active slippage control (ASC) provides precise position control all the time – every time. This is ideal for monitoring applications where repeatability and accuracy counts.


Advanced NDT applications are getting more and more widely used in the oil&gas and power industries. Requirements on repeatability and data quality are getting stronger. This is exactly what FAST-UT offers. Its probe holders are designed to ensure a proper coupling of the sensors in most of the situations while video information on the surface condition and accurate position are recorded. With its compatibility with UT, PA, TOFD and ET, FAST will allow complete inspection of welds as well as corrosion mapping in a very efficient way.


How it works

Depending on the application the operator assembles the system to either weld following or corrosion mapping. The complete setup and commissioning is done in less than five minutes and does not require any tools. The individual modules are simply plugged together and connected to the on-board electronics.

accessibility & productivity

The FAST UT allows the operator to inspect areas difficult to access by human, and to get more coverage and data in one path. With its capacity to carry multiple sensors, it can ensure a perfect coverage of a weld seam or a wide coverage of surfaces in case of corrosion mapping. Fast UT is a human friendly equipment: configuration and set-up can be made easily using a minimum of tools. Changing from one configuration to the other can be done in seconds. Path planning and navigation aids will help to get reliable, repeatable and reproducible data, a step change for your reports. You save the very time consuming process of preparation, risk assessments, watchmen…

health & safety

Deployment of the FAST Platform is quick and easy and can eliminate the need for human to perform unsafe inspection. Entry in confined spaces or work at height in case of overcrossing pipeline for example can be replaced by inspection from a safe & remote location. This leads to tremendous cost saving for the asset owner and the inspection company. But, more important, it can safe yours, your co-workers and partners' lives.
