The Great Lakes Tunnel, a $500-million private investment by Enbridge in Michigan, will be built deep under the Straits of Mackinac to house our Line 5 pipeline.
Enbridge support vessels now patrolling Straits of Mackinac 24/7
Thermal imaging technology confirms anchors are stowed on all nighttime shipping traffic
A large suite of safety measures keeps Enbridge’s Line 5 pipeline operating safely in Michigan’s Straits of Mackinac.
In recent days, we’ve added thermal imaging technology to our safety toolbox in the Straits.
One of those safeguards was the addition of two support vessels that monitor Straits traffic. Those vessels have been on the water since mid-October, and are now on patrol 24/7—using forward -looking infrared (FLIR) cameras at night to confirm that ship anchors are stowed.
This near-term solution, along with a vessel communication system and high-resolution cameras, makes the Straits safer for all utilities traversing the bottom of the Straits.
Ultimately, a tunnel will eliminate the possibility of an anchor strike, with a replacement Line 5 pipeline housed within foot-thick concrete walls about 100 feet below the lakebed.
