VOSTA LMG has delivered, assembled and commissioned a cutter suction dredge to be used for potash production in the Dead Sea by her owners Arab Potash Co. from Jordan.
The design is specific for the harsh corrosive environmental conditions in which the dredge has to operate, thus the use of specific materials, adequate cooling capacity and cleaning devices for coolers. Due to the location of the Dead Sea, the dredge was transported by sea and land to her final destination. This is why the dredge was made dismountable. The use of digital technology and modular design allowed for easy disassembly and assembly. The dredge is a stationary dredge equipped with two spuds on the aft side, which can be hoisted and lowered in a controlled manner. The bottom parts of the spuds are weighted to increase impact during controlled lowering and penetration of the ground. One of the spuds is installed on a spud carrier, which is moved by means of a horizontal hydraulic cylinder. The swing is performed via two side winches installed on the ladder, under the control cabin. The anchors are placed by two anchor booms, located on the forward pontoons on both sides of the vessel. The cutter is driven by a hydraulic motor. For maintenance purposes a cutter platform is provided. The dredge excavates at an average depth of two to three metres.
