number of available options. The non-self propelled dredgers consist of an ergonomically designed operating cabin, a main pontoon housing the diesel engine and the dredge pump, plus side pontoons, the cutter ladder and the spud poles. The pontoons are fitted out with a simple yet heavy duty coupling system enabling.

expectations, and its dredges have proven to be sound investments. his tradition started in 1885 when Charles Ellicott started a machine shop in the growing city of Baltimore, Maryland. Business thrived, and in 1888 he was approached by a local contractor and asked to design and build new machinery for a dredge that.
During operation the dredger moves around a spud pole by pulling and slacking on the two fore sideline wires. This type of dredger is capable to dredge all kind of material and is accurate due to their movement around the spud pole. The stationary cutter suction dredger is to distinguished easily from the plain suction.
mounted on top of a vertical cylinder which ends under the keel of the dredge. The excess water is discharged under the dredge, which is the lowest level possible, thus minimising the dispersion of fines into the surrounding waters. Further, the design of the overflow is such that, by avoiding the entrapment of air in the.
Dredging vessels are designed for excavation activities usually carried out at least partly under- water, in shallow water or fresh water areas with the purpose of gathering up bottom sediments and disposing of them at a different location, mostly to keep waterways navigable. To perform these tasks dredgers are equipped
Damen builds those ships. When it comes to dredging, Damen delivers the complete range of vessels and services needed for the job. Our dismountable Cutter Suction Dredgers have extremely short delivery times and, like our Trailing Suction Hopper Dredgers, they are based on latest technology, research and design.
Main characteristics. • Free sailing. • Self-propelled. • Self-loading when trailing. • Self-unloading or -discharging. • Seagoing or inland waterway vessel. • All “non-rock type" soils. • Relatively insensitive for waves. • Not vulnerable for shipping.

One or more suction pipes with suction mouths, called dragheads that are dragged over the seabed while dredging. • One or more dredge pumps to suck up the loosened soil by the dragheads. • A hold (hopper) in which the material sucked up is dumped. • An overflow system to discharge the redundant water. • Closable
