De Groot Delivers Versatile CSD for Suez Canal Authority

De Groot Nijkerk Dredging Equipment is supplying the Suez Canal Authority with a complete assembly package for their type CZ450S cutter suction dredger. The pontoon is being built and the vessel assembled at the Port Said Shipyard in Egypt under the supervision of an engineer from De Groot's parent Damen Group.

De Groot Nijkerk is engineering the complete dredger and supplying the drawings for the pontoon as well as the dredge pump, the cutter unit including the heavy duty ladder, the spud carriage, winches, hydraulic and electrical installations and the dredging instrumentation.

The dredger will perform general service tasks in the Suez Canal area and has been designed to dredge various difficult local materials including gravel, hard conglomerate gypsum, sticky clay and densely compacted sand at depths ranging from 2m to 11.5m and discharging through a 450mm diameter pipeline to distances up to 1,200m.

The monopontoon dredger features an 820kW Caterpillar 3512 engine driving a Grotius type BBP-45-1100 double walled dredge pump. A 673kW Caterpillar 3508 is installed as an auxiliary engine to power the electric and hydraulic systems, the latter of which drives four side wire winches and the cutter ladder. One fixed spud and one spud carriage are provided, the spuds being hoisted by hydraulic cylinders.

The vessel will be classed for Coastal Service by Bureau Veritas and will be able to work 24 hours a day, with a kitchen/ messroom, shower and toilet and sleeping accommodation.

A spacious control room above the accommodation will house full dredging instrumentation.

Provided by De Groot Control, this includes vacuum and pressure indicators and a production meter including a magnetic inductive flow meter.
