Transport Canada is expected to look into why a large bulk carrier docked at Windsor Terminal almost broke free.

The Algoma Niagara resumed unloading gravel at Coco dock on Tuesday after it broke its moorings early Monday morning and the crew issued a distress call on the Detroit River.

Windsor Port Authority president and CEO Steve Salmons says it caused a few tense movements as the bow swung out into the channel, but fortunately no other vessels were nearby.

Salmons tells CTV Windsor a section of the river was closed to water traffic for a period until tugs pushed back the 734 foot bulk carrier.

Kinder Morgan reported to the authority a pipeline which runs underneath wasn't damaged when the anchor was dropped.

The Algoma Niagara had to detach its anchor, which will be recovered later.

Salmons adds the Canadian registered vessel is only two years old.

In a statement to CTV News, Transport Canada says Marine Safety Inspectors are currently deployed to inspect the Algoma Niagara and "it continues to collaborate with all implicated parties as the circumstances of the vessel’s incident are being identified."
