Grand River Navigation was set to finalize a salvage plan and present it to the U.S. Coast Guard for review and approval late yesterday. Efforts to refloat the vessel are scheduled to begin Friday evening.
The St. Marys River is closed to commercial vessels from the Soo Locks to Six Mile Point.
After the Calumet was refloated by offloading ballast water, it then sailed under its own power to anchorage near Lake Nickolet where it underwent an exterior and interior examination.
A safety zone of 200 yards is being enforced around the vessel's current position.
"The Army Corps is going to look at the area of the river where it was grounded and from there, they'll determine if and when they can open up the channel", Coast Guard Master Chief Alan Haraf told the News Tribune. No pollution was observed. The merchant vessel Calumet left ESSAR Steel in Sault Ste.
Contracted divers conducted an initial assessment of the vessel's stern and determined that it is structurally sound.
The cause of the grounding remains under investigation.
A 191-metre US cargo ship remains stuck in shallow water on the St. Mary's River after running aground Wednesday night. The ship was not carrying any cargo, which made freeing it less complicated.
