ST. IGNACE, Mich. (AP) — Enbridge says it has retrieved an anchor that broke away from a maintenance vessel while on the bottom of the Straits of Mackinac.
The mishap occurred last Wednesday as a contractor was doing seasonal work on the underwater section of its oil pipeline called Line 5.
The contractor deployed an anchor about halfway between the line's dual underwater pipes.
When the crew later tried to raise it, the shackle connecting it to the cable failed.
A crane on a barge was used Sunday to lift the 15,000-pound object to the surface.
