Silloth's tanker trade comprises the import of bulk liquid molasses for use in animal feed formulations. The sugar refining byproduct is traded as a world food commodity & sourced throughout Europe for delivery to Cumbria.
Specialist Edible Oil Tankers capable of maintaining the cargo at 40deg C are required for transporting & discharging the viscous liquid.
Liquid molasses are pumped out into dockside storage tanks before being transferred to the adjacent processing plant for conversion into 'Crystalyx' animal feed concentrate.
The tidal deep water channel of the outer Marshall Dock can be kept clear by use of a metal sluice gate mechanism on the dock gates.
At low water the sluices are opened and accumulated silt flushed away. However, dredging is still needed for a more extensive clearance of the inner & outer docks.
Silloth is part of the Associated British Ports Group. A traditional Grab Hopper Dredger from the fleet of UK Dredging, whose parent company is also ABP, is used.
