MASSENA -- A Canadian-flagged ship that ran aground near Massena last week remains stuck despite multiple efforts by crews to dislodge the vessel.

According to GLS officials, the Motor Vessel Tim S. Dool remains grounded despite the efforts of three tugs to dislodge the ship last Friday.

An underwater survey was also conducted prior to the effort.

The Dool, which was carrying grain, ran aground on Nov. 23. The cause of the incident remains under investigation, however no injuries were reported as a result.  

Officials say the ship was outside of the shipping channel and has not affected traffic on the Seaway, though vessels traversing that area are traveling slower than normal.

Lt. Phillip Gurtler confirmed there were no reports of oil or fuel spilling into the river.

Lt. Gurtler is with the U.S. Coast Guard in Cleveland.

Officials say they will now seek to remove some cargo from the vessel to lighten the load, hoping it will reflect the Dool.

If that were to happen, the waterway would likely be closed briefly, officials said.

Efforts continue with the Canadian Coast Guard, Great Lakes and St. Lawrence Seaway Development Corp. crews and the National Response Corp.  all utilizing their resources.
