Great Lakes and St. Lawrence Seaway

MV Frontenac was built by Davie Shipbuilding in Lauzon, Quebec, Canada as a straight deck bulk carrier in 1968, and converted to a self-unloader at Collingwood Shipyards in 1973. It is a maximum size Great Lakes / St. Lawrence Seaway size self-unloader and is fitted with a bow thruster and a variable pitch propeller with conventional rudder.

The equipment on board MV Frontenac consists of hopper type cargo holds which feed material through a series of hydraulically operated cargo gates. The material is then fed onto two continuous loop belt conveyors that run the length of the vessel and elevate the cargo to the main deck and onto the vessel’s stern unloading boom of 76.84 m in length.

This vessel is also fitted with an environmental containment and recovery system (ECARS) that significantly reduces the amount of dust and other particles during unloading.

MV Frontenac is wholly owned and operated by CSL.
