Confidential Client – Salt and Caustic Handling Dock
Matrix PDM Engineering completed an opinion of probable cost (OPC) for the design of modifications to an existing dock to allow solid salt unloading and liquid caustic loading. Matrix was then awarded the next phase of the project.
The final design modifications to the dock and the design of the hopper and conveying system allowed for unloading solid salt from barges into a hopper using a hydraulic material handling machine. The hopper continuously feeds the salt onto a conveyor and discharges it into a slurry tank at a rate of 250 tph.
Matrix also designed the liquid caustic loading arm to load tanker barges. In addition to the design required for the dock modifications, project management services, including equipment procurement, document control, and scheduling were provided.
