Inside the AI models powering autonomous pipeline inspection

A look at how NOPOL Subsea trains and deploys the computer-vision models that flag pipeline anomalies in real time, from raw sonar to a ranked inspection report.

Inside the AI models powering autonomous pipeline inspection

Every inspection run generates far more footage and sonar data than any human reviewer could examine in real time. Our onboard AI models exist to change that ratio, flagging the handful of frames that actually need an engineer's attention out of hours of raw feed.

The models are trained on a growing library of annotated subsea imagery: corrosion, coating damage, free-spanning pipe sections, marine growth and third-party interference. Each new inspection campaign adds to that library under expert review.

In the field, the models run close to the vehicle, scoring anomalies as they are seen and building a ranked list that is ready for our engineers before the vehicle has even surfaced.

“We are not trying to replace the inspection engineer's judgement, we are trying to get the right footage in front of them faster.”
