The Swift and Scorpion2 dry-coupled, remote-access ultrasonic crawler bring major efficiency and data improvements to tank shell inspections and other structures such as vessels and offshore installations.

Ultrasonic Performance

Scorpion2 is equipped with the best ultrasonic electronics and software the industry has to offer. With its advanced filtering, the system can inspect materials 4.7–100 mm (3/16 in to 4 in) faster and more accurately than other solutions on the market. The Swift™ software enables unique UT gate processing (such as floating and tracking gates), ensuring correct wall thickness measurements under most circumstances.

Scorpion2 Crawler

Probe Design

The unique, Silverwing dry-coupled ultrasonic wheel probe eliminates the need for couplant or for a constant water supply. The probe is designed as a twin-crystal ultrasonic probe combined with a unique rolling probe face.

Probe Carriage 

It enables the solution to record thickness measurements in the critical heat-affected zone (HAZ), 25 mm (1 in) from a weld cap. The four independent-power magnetic wheels and their treaded tires offer Scorpion2 the ability to easily move over 12.7 mm (1/2 in) bumps and an excellent grip under any condition.

Active Probe Lift and Balance

Unique to Scorpion2, active probe lift raises the wheel probe when measurements are not recorded, extending the life of the probe’s tire. Active probe balance makes it easier and faster to set up the probe before inspections, increasing inspection repeatability.

Battery Powered

Scorpion2 comes with two lithium-ion battery packs for continuous on-site operation. It uses one battery mounted inside the crawler, removing the need for a separate power source, as well as reducing umbilical and overall system weight.


With its large, 26.4 cm (10.4 in), non-reflective, multi-touch screen, Swift offers crystal-clear displays under any lighting condition. It is equipped with a powerful ultrasonic card that works seamlessly with the B-scan software. Setting up ultrasonic and inspection details has never been this easy. Swift is sealed and designed for IP65. Its magnesium alloy casing is tough, water and dust resistant. Combined with 3 mm (1/8 in) strengthened glass, it’s the perfect instrument for harsh environmental conditions. Swift uses two lithium-ion, hot-swappable batteries, making a full day’s work easy. Swift can also be used with an optional harness to make using it for longer periods of time less strenuous. The adjustable stand, the top handle, and the four corner anchor points make Swift extremely practical on site.

Data Acquisition Software

Swift B-scan data acquisition software features several powerful data review, reporting, and printing tools. You can review saved data at any time with active A-scan and B-scan displays. Placing the cursor over any part of the B-scan profile shows the A-scan trace for that specific section of the scan. Furthermore, you can display an adjustable reporting threshold indicator over the B-scan profile, helping identify reportable defects at a glance and enabling rapidly analyzing complete scans. The full-amplitude B-scan mode helps characterize wall loss, which, in turn, makes detailed post-inspection analysis and accurate corrosion assessments possible. You can export data as CSV files, A-scan and B-scan images, or as CMX files, which you can then import in CMAP inspection management software. When you do, all your scans are automatically positioned based on X, Y coordinates, providing a complete overview of inspections.
