Skygauge Spot Thickness Test vs. Testing by Hand

How Skygauge Robotics saves time and money on UT Inspections

Project Overview

How Skygauge Robotics saves time and money on UT inspections. The Skygauge Inspection Drone provides a safer alternative to conventional UT inspection methods at height while saving customers both time and money. Rope access is the most cost-effective conventional method for conducting UT inspections at height. This comparison study demonstrates the money and time saved when using Skygauge compared to a rope access inspection team when conducting a UT inspection of five welded steel storage tanks at an oil refinery.

CHALLENGE

Skygauge Robotics reinvented the drone for ultrasonic testing, cutting inspection costs by 30-50%, and reducing inspection time by 10x. But how does our test compare to an ultrasonic reading taken the traditional way? Skygauge partnered with Paul Holloway of Holloway NDT & Engineering to prove that there is no difference between a Skygauge inspection and a conventional one.

Paul joined us at our test facility in Hamilton, ON, to run a series of tests on an industrial stack. The results were astounding, with Skygauge matching the manual results on every test conducted!

Both Paul and the Skygauge crew ran 3 tests in specific locations for consistency, including one with notable signs of external wall loss (pitting). The surface was carbon steel, with Paul and Skygauge both using a D7906 transducer.

The nominal material velocity for carbon steel was set for the handheld UT instrument and the drone software, and both transducers demonstrated correct calibration on a suitable reference block.

Readings were performed using the echo-to-echo technique to maximise repeatability and control variances due to contact force. 

RESULT
  • Skygauge took 3 days to complete the inspection, while the rope access team took 7 days.
  • A Skygauge inspection cost the customer $10,390, while the rope access inspection cost $28,480.
  • Choosing Skygauge reduced UT inspection time by 60% and costs by 64%.

In the words of Paul Holloway
“All readings performed via drone were within the maximum and minimums recorded using manual UT.”

TRADITIONAL SOLUTION -ROPE ACCESS
  • A team of three double certified rope access and NDT technicians scales the side of the tank on ropes, taking considerable personal risk and delivering 6 UT readings per hour.
  • Total inspection time 7 days.
  • Total inspection cost $28,480.
RESULT
  • Skygauge took 3 days to complete the inspection, while the rope access team took 7 days.
  • A Skygauge inspection cost the customer $10,390, while the rope access inspection cost $28,480.
  • Choosing Skygauge reduced UT inspection time by 60% and costs by 64%.
