Trailing suction dredger
1,With good sailing performance, it can carry out construction work under relatively bad sea condition.
2, With self-sailing, self-digging, self-loading and self-unloading performance, in the construction work does not require tugboats, mud barges and other vessels. Convenient dispatch, can be quickly transferred
3,In the dredging operation, there is no need for anchor, cable, winch, positioning pile and other equipment, and the ship does not occupy the water during the dredging operation, no need to block the channel, which has less influence on other ships.
Disadvantage: Since the operation is self-navigating, the levelness of the soil layer after construction is poor.
Cutter suction Dredger
1,Suitable for the dredging project of port, river, amber, and the excavation and construction of newly built port channel under the condition of wind and wave.
2, Especially suitable for land-blowing project, under the condition that the distance between the conveyance and blowing is satisfied, it is appropriate to use the cutter suction dredger for direct excavation and blowing operation.
