Modification of Underground Marine Pipelines at Section 70 of the Port of Montreal, Borough of Mercier-Hochelaga-Maisonneuve, Montreal, Quebec

Terminal Norcan Inc. operates an oil terminal that supplies numerous service stations in Quebec and Ontario. The facilities are supplied by vessels via two marine pipelines connecting Wharf 74 to the Norcan terminal, located at 6370 Notre-Dame Street East in Montreal, across from Section 66 of the Port of Montreal.

 

The work will take place in Section 70 of the Port of Montreal, on lots 1,773,871 and 1,773,873 of the Quebec cadastre, on federal land managed by the Montreal Port Authority.

 

The terminal has been in operation since 1935. Over time, the marine pipelines have been relocated several times. Those targeted by the present project are underground, have a diameter of 14 inches, and were installed in 1987. The project involves replacing two underground sections, each 94 meters long, at Section 70 of the Port of Montreal, part of which will be above ground. The work is being carried out as a preventive measure. It should be noted that Terminal Norcan regularly inspects its marine pipelines using an intelligent pig.

 

Access to the underground pipelines is constrained by their location alongside rail tracks of the Port of Montreal, as well as beneath the railway siding serving the Catelli company. To access them, it will be necessary to lower the ground level on the north side, which is currently used as a parking area by employees of the company Termont. A 2-meter-high concrete block retaining wall will need to be dismantled and then rebuilt after the work is completed.

 

The work will be carried out in the fall of 2026.
