A Nova Algoma Cement Carriers vessel remains aground a day after the ship suffered a casualty in the St Lawrence Seaway, blocking the waterway that links the Great Lakes to the Atlantic.

The location transponder of the 14,000-dwt NACC Argonaut (built 2003) is broadcasting that it is aground in the St Lawrence River east of Cornwall, in the Canadian province of Ontario, according to tracking data provided by VesselsValue.

The ship is laden with a draught of 8 metres.

The vessel was travelling from Montreal to the Ontario port of Oshawa on Sunday morning when it ran aground, bringing traffic on the river to a halt, according to broadcaster 7News.

There were no injuries in the incident or pollution in the waterway.

Claims consultancy WK Webster told clients that a tug was on hand to help the vessel refloat.

“It is reported that the vessel was initially refloated and was able to resume its voyage, albeit with restricted manoeuvrability, but has since run aground again,” the company said.

The ship is controlled by Nova Algoma Cement Carriers, a joint venture of Switzerland’s Nova Marine Carriers and Canada’s Algoma Central.

Algoma Central’s offices in Canada and the US could not be immediately reached for an update on Monday. Canada’s St Lawrence Seaway Management Corp, which jointly administers the waterway with its counterpart in the US, also could not be reached for this story.

The Canadian-flag NACC Argonaut is managed by Ontario’s Algoma Ship Tech and classed by Registro Italiano Navale (Rina). It has insurance from NorthStandard.
