The two organizations’ earliest R&D success, which was patented and led to further innovations, was a new device that can be attached to a specific MFL ILI or be used after it. Called the Porcupine due to its appearance, it makes up for any deficiencies in MFL ILI equipment accuracy. This was followed up with the development of an enhanced MFL ILI that uses rare earth neodymium iron boron magnets to power the magnetizer. Doing so provides the strongest type of magnet available in an MFL ILI, and has a high degree of accuracy in the detection of pipeline thickness and leak sizes.
