To extracted sand at a depth of 45 meter this special deepwater dredge is designed. This design of the dredger is based on low operation cost. This is done by keeping the design as simple as possible and ensuring that maintenance work can be done easy and fast. The extraction of sand is done in a small pond because of this calm water the design of the dredger was simple and non-traditional. However dredging on a depth of 45 meter is a big challenge. The dredge starts at water level with extracting sand and goes to the depth of 45 meter without changing the configuration of the dredge. It is possible to extend the dredging depth to more than 60 meter.
