"SUSANNA II"

The "Susanna II" is a fully dismountable cutter suction dredger equipped with a 250 mm discharge pipeline. It was fitted out with a swing ladder for dredging at a maximum depth of 6 metres. The dividable swing ladder has a total length of 18 metres, which delivers an impressive and hyper-efficient swing width of 28 metres. Moreover, the "Susanna II" is equipped with a spud carriage installation with a 2 meter stroke and spuds that can work both on land and water. The control cabin can be dismantled so as to keep the maximum height of the full dredger under 1.5 metres for swift passages under low bridges. For easy transport, the modularly designed dredger comes apart into a main pontoon, four side pontoons, the control cabin, the spuds and the dividable cutter ladder, all of which can then be transported by road.

“Igor Mazursky” & “Fitzgerald”

The “Igor Mazursky” and “Fitzgerald” are 2 identical electrically powered cutter suction dredgers, built in Canada to a Damen design and using Damen major components. Damen Dredging Equipment provided the dredging engineering and design in addition to parts such as pumps, winches and cutter heads, and the provision of all major items including motors, steel package and electric and hydraulic installations.

The two 40.64-metre long vessels perform dredging duties in oil sands tailings ponds. The dredgers have been fitted out with Damen dredge pumps type BP6560MD that feature a variable-frequency drive with a 2.200 kW electric motor. The hydraulic installation is powered by a 600 kW electric motor which feeds the 250 kW cutter head and the winches. Each CSD pumps 7,200 m3 per hour at 6.5 bar. The electrically-powered design receives its power supply from a 13.8 kV ship-to-shore cable.

“AMORIS”

The “Amoris” is a electrically driven CSD450, fitted out with a number of specific design elements to make it fit for it’s specific operations in the polluted silt treatment plant of SeReAnt in the harbour of Antwerp. These features include 4 spuds of which 2 are placed in spud carriages to ensure a continuous and smooth dredging process, a heavy duty cutter ladder swings by means of hydraulic cylinders as well as a barge unloader with empties barges moored alongside.

The entire dredger including its dredge pumps is electrically driven, the required total power on board being 15.75 kV at 1.800 kVA. The dredge pump capacity for both the cutter action as well as the barge unloader is some 3.000 m3/h. The fully automated dredger features for instance dredge pump capacity control, swing ladder control, and automated coupling to the shore-based treatment plant.

“SAUGER III”

The “Sauger III” is a floating pump station owned by Hamburg Port Authority. The stationary pump station features a powerful, dual pump installation, a comfortable accommodation for the crew and measures 37 meters in length and 10 meters wide. It’s main aim is to empty barges coming alongside, using a suction arm, pumping the contaminated silt ashore through a floating pipe line. A second arm adds water to the cargo for fluidization.

The entire operation requires a crew of just two men, and is managed from a state-of-the-art pump control room. It is powered by electricity supplied via a shore connection with a transformer that converts it to the 690v and 400v necessary for the 2 Damen dredge pumps on board. The station is moored against piles and does not have an independent propulsion system. The vessel has been designed and built to comply with all German regulations and is certified by Germanischer Lloyd.
