CSL Laurentien

Great Lakes and St. Lawrence Seaway

MV CSL Laurentien is one of Canada Steamship Line self-unloading Lakers. She was built in 1977 and converted to a self-unloading vessel in 2001.

The equipment onboard consists of hoppered holds with 35-degree slopes and hydraulically operated roller track gates. Two tunnel conveyors run the length of the vessel and feed two cross conveyors that run toward the ship. A single loop belt elevating system raises the material to the main deck and onto the vessel’s unloading boom.

Self-contained PC workstations connected to a network permit remote control and automation of both the unloading and ballast systems.

MV CSL Laurentien is fitted with a dust covering and a fixed spill tray on the unloading boom. Wash down holding tanks retain cargo hold residue and wash down water. The unloading tunnel is ventilated for coal and is fully explosion-proof. Tunnel gates are operated by remote control.

MV CSL Laurentien is wholly owned and operated by CSL.
