Cutter Suction Dredgers (CSD)

The Hollandsche Yssel cutter suction dredgers are well known for its robust construction, reliable operation and excellent performance. To date De Hollandsche Yssel have supplied over 550 stationary dredgers of which over 220 cutter suction dredgers. Three ranges of standard designs are available: The standard traditional range of cutter suction dredgers, the standard range of self manoeuvring cutter suction dredgers and the custom made cutter suction dredgers.

Not surprisingly, all types of cutter suction dredgers have a very good price/what you get ratio. Also buyers of the standard traditional cutter suction dredgers are advised and treated personally to ensure a well balanced choice of their cutter suction dredger.

The principal features and particulars can be found on this web-site. For each type a brief specification is available on request. Please contact us if more information is required at info@hollandscheijssel.nl

The current range of standard traditional cutter suction dredgers consists of the basic model, with power outputs ranging from 200 to 1,600 horse power.

The current range of standard self manoeuvring cutter suction dredgers consists of the basic model, with power outputs ranging from 200 to 600 horse power.

The current range of custom made cutter suction dredgers consists of a wide variety of models, with power outputs ranging from 200 to 1,600 horse power. Even these custom made cutter suction dredgers are based on the Hollandsche Yssel’s standard dredging components, i.e. the standard double walled dredge pumps, standard cutter heads, standard winches and even standard hydraulic systems, double walled pump- and cutter drive systems.

Hollandsche Yssel dredgers have a main engine and the dredge pump mounted on a rigid frame. The dredgers are equipped with double walled high-pressure dredge pumps. These high efficiency double walled dredge pumps are directly driven by the main diesel engine, via a standard gearbox with integrated hydraulically activated clutch. The prime movers for the dredge pumps are modern marine diesel engines with low fuel consumption, and low NOx emission.

This combination results in the lowest possible costs per cubic meter of dredged material, minimum down time for changing of wearing parts and minimum cost of maintenance and spare part due to standard engines and gearboxes. The type designation of the Cutter Suction Dredger relates to the diameter of the suction and delivery pipeline.
