Landlocked tug

Construction of foundations for the Queen's Marque project on the Halifax waterfront is taking place below sea level. In order to carry out the work a seawall has been built out of sheet piles to keep the water out. Pile driving for the work and placement of the sheet piles has been carried out by a crane mounted on the deck of a sectional scow, built out of smaller pontoons.





To move the scow, Dexter Construction is using one of their miniature tug boats. It and the scow are working inside the Sea Bridge floating walkway built for the Waterfront Development Corporation to allow pedestrians to bypass the construction site, from the water site. The Sea Bridge, stretching from the Cable Wharf in the north to the Maritime Museum in the south provides an excellent view of construction activity.

A.F.Theriault + Son of Meteghan, NS, built a pair of the tugs for the Municipal Group, parent company of Dexter Construction, and they worked first on the Halifax Shipyard pier 6 project. Since the tugs are small enough to be transported by truck, they can be used in a variety of locations not normally accessible by watercraft. Because they are under the 15 tons they are not registered by name, but only by number, in this case C20115NS.



One of two aluminum hulled tugs, that are transportable by road, powered by twin Yamaha outboard engines with a total of 230 horsepower.


Scow and crane are tucked in between the Cable Wharf and the remnants of the old timber piled Queen's Wharf.
