Description of Ship

5500 m3 Trailing Suction Hopper Dredger

The vessel is designed as a self-navigated Suction Dredger suitable to scour port and channel,encircle sea,blow/fill and build land and worked for costal  area.

This vessel is a self-propelled trailing suction hopper dredger of full steel welded, streamline and round-bilge hull with twin screw, double  rake, single deck,bulb bow and double skegs. It can navigate

in unrestricted navigation area and operate in greater coastal area.

Dredging performance

Max dredging depth

The dredging depth is 27.0m below waterline on  the condition of light load when the angle between dredge pipe and water level is 45o

Loading time

The loading time is about 45min when dredging medium fine sand of hardness below middle level and two racks operate together and the dredging depth is 27m.(to be final confirmed by the pump efficiency.)

Hopper capacity

Max hopper capacity is 5500m3,and max mud loading capacity is 7150t.The distance from liquid level to upper edge of hatch coaming is 600mm(the highest position of overflow ladle).
