HULL AND SUPERSTRUCTURE■ The dredger is dismountable in
main pontoon, four side pontoons,operating cabin, cutter ladder,gantry and spud poles, whichpermits easy transportation byroad, rail or ship to nearly anylocation
■ 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 andan easy way
■ Three separate engine roomhatches for optimal maintenanceof engines and dredge pump
■ Collision bulkhead at the aft ofthe main pontoon
■ Double bollard on fore and aftand one single in the middle ateach side of the dredger
■ Store with large hatch, woodenfloor and shelves, and lighting
■ Chequered aluminium floor platesin engine room
■ Removable railing made ofstanchions and stainless steelwires
■ Marine coating system andcathodic protection for inland-and seawater use
OPERATING CABIN■ Very spacious operating cabin,
easily accommodating 2/3persons. The cabin is ergonomicdesigned according to the latestinsights
■ Standard equipped with air-conditioning and heating
■ Mounted on shock absorbers to minimise vibration and noiselevels
■ Constructed of steel and wellinsulated
■ Two ergonomic designed controlpanels with a dredge master chairin between
■ Dark tinted double glassed
windows all around of which one can be opened, providingexcellent view of all essentialdeck equipment
■ Window wiper at front- and aftwindow
DREDGE EQUIPMENT■ High efficiency dredge pump,
built up with Ni-hard4 wearingplates and pump casing andBainitic Nodulair impeller
■ The shaft is sealed using amechanical seal
