Method of Operations

The dredger is a cutter-dredger type, which has a cutter at the end of the suction pipe ladder.

The cutter here is the drilling bit.

It is lowered onto the seabed where it loosens the sea-sand by its rotary action.

The suction pipes of the dredger can be lowered 22 meters into the waterbed. Few dredgers go near this depth.

The loose sand together with water is sucked and pumped into the floating pipeline to a sand fill site.

This is the hydraulic process of winning the mineral sand.

Here the water-bearing sand discharges its load of water and sand at the end of the floating pipeline, while water runs off through the water box and thence back to the sea.

Often a booster station, stationed between the dredger and the sand fill site is more than one and a half kilometers.

At the sand fill site, the sand so deposited is spread or “pushed out” with a bulldozed.

Minor and temporary Water Courses are created with the bulldozer to conduct the water to the water box and thence to the sea.
