General Introduction

u This cutter suction dredger is designed to operate in sheltered inshore waters and under tropical climate conditions. Build under enterprise standard.

u The whole dredger is dismountable in road transportable sections.

u The engines and dredge pump are located in the center pontoon, the 2 side pontoons serve as fuel bunkers, ballast tanks and store.

u Engine room and pump section are accessible by watertight hatches

u Cutter shaft runs on roller type bearings in an enclosed shaft housing flooded with lubrication oil a lock oil tank to ensure a positive pressure inside the bearing housing is located on top of the wheelhouse.

u The spacious control cabin is ergonomically designed fitted on a raised platform with all around non obstructed view ,2 operators consoles containing engine instrumentation and controls for winches, dredge pump, suction and discharge pressure gauges, navigation light controls, airconditioned and well insulated .

u Below the control cabin is a changing room located with table, chairs and washbasin

u The underwater section of the dredger is protected with a marine coating system and cathodic protection for use in a saltwater environment

Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
The work of a cutter suction dredger works through an agitator in the head of a straw and straw.
Q:The working principle of a trailing suction dredger
The ship is equipped with one or several sets of centrifugal pumps, centrifugal pumps for absorbing water and mud from the bottom of the vessel, into the mud tank. These operations are carried out on the voyage, while air while digging, mud tank fill to throw mud mud area, through the Bilge mud. Handle cases
Q:The famous type of cutter suction dredger
MAN provides engines for the world's largest suction hopper dredger.
Q:Classification of trailing suction dredgers for trailing suction dredger
Trailing suction dredger is one of suction suction type. It sucks in mud by raking the head of the two side of the ship's hull or at the tail to work with mud and side navigation. Is the use of mud rake scarification, boat design sediment tank, tank volume said the size of the ship. A single to rake or harrow, are arranged on the ship or on both sides. Suction dredger is flexible, high efficiency, strong wind waves, suitable for coastal ports, the wide river and ship anchorage operation in large waves and without the cover of coastal and estuarine areas, should choose the self-propelled trailing suction dredger. Soil works suitable for loosening and less than clay hardness. The self-propelled boat is equipped with a mobile power unit (paddle machine) to drive the dredger.
Q:3800m3 cutter suction dredger
The 3800m3 cutter suction dredger says 3800m3 of sediment can be dug per hour!I designed the dredge pump, the ship is generally named after dredging flow, but also by the flow of water named
Q:Does dredging dredger need relevant qualification?
This should be based on the requirements of your local department, which is not required in general
Q:Who has the construction plan of dredger dredger after dredger dredging and dredging with dredger barge?
Would dig into the mud barge, barge by suction dredger, using force pump suction dredger through pipelines on shore
Q:Advantages and disadvantages of trailing suction dredger for trailing suction dredger
Therefore, the utility model is very suitable for the construction of canals and canals in ports or navigable ships. The disadvantage of a trailing suction dredger is that the bottom of the dredger is hard to dig
Q:What are the crew members on the dredge?
The dredge work generally is not very tired, after all, the mechanization of things, the need for artificial little ~ ~ for one is general and maintenance of turbine operation, as well as the ship fuel supply etc..
Q:What is the working principle of a cutter suction dredger?
Adjust the transverse retractable cable winch, traverse speed and stop, to change the movement speed and cutting cutter position change in different sections. The mud pump is then pumped through the sludge line and the muddy water mixture is delivered to the designated blow in area. The cutter suction dredger by dredging machinery and equipment according to the design requirements of the excavation dredging area of rivers and lakes, and the dredged material through the mud pipeline transportation to dike back water side with fill; it is conducive to the expansion of cross-section, and it helps to prevent the foundation piping failure. It has been widely used in river and lake dredging works.
