[Compact Rings are] much lighter and easier to manipulate. The new joint/clasp system is great and very easy to use, with no risk of dropping fasteners bolts through grating! I love the idea of only moving a LEMO to change spacing - this will allow so much more data to be collected for rope access applications, which will give a better quality inspection.

...The new compact collars are excellent and the new connector configuration on the modules is very easy to use! Thank you for the new lightweight G4mini and Tablet Toughbook! It has proven to speed up production!

Thanks to [one of GUL's experts], I was finally able to get the correct setup for data collection and analysis on high noise pipelines.

... Then, I was successfully able to get data from pipelines for which collection had previously failed due to High Noise Level, while also confirming that the initially poor Signal‑to‑Noise ratio was far improved: from 20dB to 60dB.

... Through the comments posted and shared on GUL Facebook, I became aware that GWT using Compact rings and modules allows easier detection of even smaller defects, a more efficient operation, and clearer signal.

... I do appreciate GUL's readiness to help us.

I just wanted to thank you for arranging the hire of those HT modules. Your customer service was (is) excellent and well appreciated.

I am just sharing photos taken last week in Alaska using the fantastic extreme temp cables at -68°F. Our inspector is extremely happy that he doesn't have to deal with regular cables anymore in the winter time. Thanks to you all for the continued support.

I was recently fortunate enough to witness an impressive guided wave testing (GWT) demonstration where verification of a previous inspection result was required. The organisation that was responsible for the inspection was not aware that we were going to carry out a re-inspection of the pipe section and the available equipment was different to that which was originally used. The original inspection used a Wavemaker G3 and the re-inspection was performed with a Wavemaker G4 and a different transducer ring.

Equipment set-up and data collection took a very short period of time, just a few minutes per test location. The result from the verification test was overlaid on the original data trace and, after a slight adjustment to accommodate the different position of the transducer ring, a direct comparison could be made. What was very impressive was the similarity between the initial results and the retests; there were minimal differences. Two further pipes were tested and the traces were overlaid on the previous results and, again, the repeatability was very impressive. This is from a method that can test 1 km of insulated pipe in a day without removing all of the insulation or taking it out of service.

The method does have some limitations, but there are many practical applications where it can offer significant advantages. One such example is for the monitoring of pipe condition using a permanently-installed transducer ring. This allows repeat measurements of inaccessible pipe sections to be taken ‘at will’. Overlaying the results gives a precise measurement of pipe degradation.
