International Dredging Review

International Dredging Review

McNally Marine is nearly finished a port expansion project at the Port of Belledune New Brunswick Canada on the Gulf of St. Lawrence south of the entrance to the Seaway. The company is using mechanical dredges for the dredging and excavators and clamshells to unload the scows.

The project includes installing a 400-meter dock to expand the Ro-Ro capacity of the Port of Belledune and deepening the inner and outer harbor navigation channels to 17 meters. Dredging amount was 200000 cubic yards of soft sediment.

The company used an 895 Liebherr crane equipped with a 16-cubic-yard Cable Arm bucket and a Liebherr 885 equipped with a 13-cubic-yard Cable Arm bucket for the dredging loading into scows that took the material to a shore-based rehandling station. There the material was loaded into rock trucks then taken to in-water sealed holding ponds. The material was unsuitable for ocean disposal.

McNally began mobilizing for the project in May 2010 bringing equipment from its facilities in New Brunswick Québec Nova Scotia and the Great Lakes. By the time of shutdown for cold weather the dredging was largely completed. At the beginning of March the area was in the middle of a six-week hiatus because of weather awaiting warm weather to complete the caissons for the sea wall of the dock.

McNally International is a privately owned heavy construction company that specializes in dredging marine construction and tunneling. The company was formed in 1949 and works on large and small dredging projects on the East Coast of Canada and tunneling projects throughout Canada and the United States with offices and equipment yards in Hamilton Ontario; Sorel-Tracy Québec; Dartmouth Nova Scotia; and Westlake Ohio.
