Line 5 inspections
Regular examinations of the pipe, both inside and out.
Prevention is a key component of safety at Enbridge. Our proactive inspection program allows us to monitor the fitness of our pipelines from both the inside and the outside.
We take extra precautions on the Line 5 Straits of Mackinac crossing, with regular inspections that make this crossing the most inspected segment of pipe in our entire North American network. These measures include:
- Thorough evaluations of the pipe's interior, using inline inspection tools. These sophisticated tools provide a level of detail similar to MRIs in the medical industry, allowing us to examine the interior walls of our pipes inch by inch, and alert us to features that may require a closer look (click here to learn more about the results of our in-line inspections).
- Regular visual inspections of the exterior of the pipe, using expert divers and/or remote operated vehicle (ROV). These external inspections provide a thorough, detailed look at the exterior of the pipe and its immediate environment (click here to find out more about our span management program).
We take special precautions to protect the Great Lakes.
