Trailing Suction Hopper Dredger is an equipped with rake head mining machinery and hydraulic Dredging Equipment of large self-propelled, binning Dredger.Dredging, will put down the bottom of the river, the suction pipes, using vacuum effect of mud pump, through the rake head and Suction Tube bottom absorbing mud into the dredger mud in the warehouse, warehouse full of mud, after sailing up the rake to spoil area open the mud disposal, or directly to dig up the dirt out of the ship. Some dredger can also be unloaded in mud warehouse of soil to suck out of land reclamation. It can have good navigation performance, self-propelled, since the load dump, and in the work in the navigation state, don't need a positioning device. It is suitable for no cover, long and narrow coastal approach channel excavation and maintenance, with most efficient when excavation of silt.

Trailing Hopper Suction Dredger

The working principle of Trailing suction hopper dredger
Trailing suction loading dredger, basically is a kind of dredging boat from the bottom of the sea, the dredging method is similar to vacuum cleaner. The ship is equipped with one or several centrifugal pump, using centrifugal pump suck up water and mud from the bottom, hopper into the ship. These operations on the voyage, air while digging, hopper filled with mud is to throw mud area, through the Bottom Door handle cases out of the mud. All ships of trailing suction hopper with its capacity to show different size, general capacity is 500 ~ 1000 m3. The smallest trailing suction can ship construction. Under the condition of the water depth around 3 largest trailing suction vessel dug deep can reach more than 3 ~ 35. The trailing suction vessel to vessel, can be in the wind and waves considerable dredging, navigation and throw mud at sea.

Classification Trailing suction hopper dredger 
Trailing suction hopper dredger is single rake or to rake, decorate in ship or both sides respectively.Trailing suction hopper dredger is flexible, high efficiency, strong wind resistance, is suitable in coastal ports, the broad river and vessel anchorage operation, in the large, coastal and estuarine area without cover, appropriate chooses self-propelled trailing suction hopper dredger.Suitable for loose and hardness below the clay soil.

Trailing suction hopper dredger's advantages and disadvantages
Trailing suction hopper dredger in the bow with more lateral thrusters, control performance is better. When construction without an anchor cable or berth, little interference for navigation, therefore very suitable for the port or navigable river, canal in construction. The disadvantage of trailing suction hopper dredger is bottom hard to dig. With plenty of water and sediment in the dredging shipped to spoil area, thus affecting production. Trailing suction vessel in infrastructure dredging and can be used in the maintenance dredging, but can't construction in narrow the scope of the waters.

Discharging of Trailing Hopper Suction Dredger
There are several ways to discharge a TSHD. The most common way is dumping the material.
Dumping - This is done by simply opening the doors that close the hopper. Once opened the substance will simply drop to the seabed because of gravity. The hopper will never be completely empty because there will always be some residue and water left inside.
Pressing - High pressure pumps will pump water inside the hopper to loosen or even liquefy the substance, which can then be pumped via long hoses over great distances (f.i. ashore)
Rainbowing - This is the same principle as pressing, but instead of transporting the substance it will simply be blown away. This is often used to create land.
Crane - It is always possible to discharge the load with a crane, but this will be a time consuming process.
