The underwater pipeline inspection video shows deep scoring along the lake bottom, then up and over the twin pipelines. Deep marks are etched in both pipelines, and there is evidence of outer protective coating loss.

Shriberg called the video “shocking.”
“There are deep gouges in the pipeline. And you can see where the anchor dragged along the bottom and skipped right off the pipeline. It’s one thing to hear about it or read about it; it’s another thing to see the visual evidence. I would guess that’s why
Shriberg called it “luck” that the anchor strike occurred on a portion of Line 5 resting on the lake bottom, as opposed to one of sections where the pipeline is lifted by supports.
“There’s a very realistic scenario where the anchor snags off it rather than skipping off the pipeline,” he said. “And there are areas of suspension very close to where this anchor hit.
“If you hit a suspended portion, all that force, the anchor is designed to grab and hold. You’ve got the force of a boat pulling against it.”
The corridor would be large enough for vehicles to drive through, allowing inspectors the ability to assess the condition of the pipeline.

Noted Duffy, “Going forward, the Line 5 tunnel project in the Straits would eliminate the possibility of an anchor strike, because the pipeline would be inside a tunnel with foot-thick concrete walls, approximately 100 feet below the lake bed.”
But that project could be a decade or more away, with the aging pipelines continuing to operate in the
