HULL AND SUPERSTRUCTURE■ The dredger is dismountable in
main pontoon, two side pontoons,operating cabin, cutter ladder,gantry and spudpoles, which permitseasy transportation by road, rail orship to nearly any location
■ Heavy duty coupling system withhooks at hull bottom and boltconnection on deck level, making(dis)assembly on land or afloatpossible in a very short time and aneasy way
■ Two separate engine room hatches for optimal maintenance of engine and dredge pump
■ Single bollard on fore and aft ateach side of the dredger
■ Store with large hatch and woodenfloor
■ Chequered aluminium floor plates inengine room
■ Marine coating system and cathodicprotection for inland water use
OPERATING CABIN■ Comfortable, ergonomic designed
operating cabin■ Mounted on shock absorbers to
minimise vibration and noise levels■ Constructed of steel and well
insulated and plated with coatedplywood
■ Two ergonomic designed controlpanels with a dredge master chair in between
■ Dark tinted windows all around ofwhich one can be opened, providingexcellent view of all essential deckequipment
■ Window wiper at front- and aft window
DREDGE EQUIPMENT■ High efficiency dredge pump, built
up with Ni-hard4 wearing plates and impeller and Bainitic Nodulairpumphousing. The shaft is sealedusing a mechanical seal
■ Cutter shaft supported by rollerbearings mounted in an oil filledcasing. The slow running hydrauliccutter motor is well protected in thecutter unit
■ Well designed cutter withreplaceable wear resistant serrated-or plain knives
■ Straight suction pipe for optimalsuction performance and lowwearing characteristics
■ Inspection pipe piece in front ofdredge pump
ENGINE ROOM MACHINERY■ Latest model Caterpillar engine,
complying with IMO regulations■ Closed freshwater cooling system for
the engine with a box cooler■ Engine can be started from control
panel both in engine room and inoperating cabin
■ Dredge pump driven through agearbox with electric/ hydraulicclutch, operated from the operatingcabin
■ Various auxiliary equipment, such asbilge-, cooling water pumps
DECK EQUIPMENT■ Side wire swing winches operated
with constant tension system,guaranteeing a stable cutter process
■ Removable railing with stanchionsand stainless steel wires
HYDRAULIC INSTALLATIONAll hydraulic motors and cylindersare operated by one radial pistonpump driven by the diesel engine. The system includes: stainless steeltank, all required electric operatedvalves, filters, gauges etc.
ELECTRIC INSTALLATIONTwo separate 24 VDC battery circuitssupplied by the alternator of thediesel engine, one for starting theengine the other for the boardnet. In engine room distribution boardand in operating cabin switch panelfor lights etc. Communicationbetween operating cabin and engineroom by PLC bus system. All cableconnections to dismountable partswith plugs for quick (dis)assemblywithout possibility of wrongconnections.
MISCELLANEOUS■ Mooring lines, life saving equipment■ Set of tools including impeller hook
and boatswain’s inventory■ Start up spare parts
