Dredging
Hopper Dredgers
|
|
|
|
This type of dredger excavates materials from the seabed, primarily by it’s forward movement and suction power, through suctionpipes and dragheads.
Hydraulic installations on board of these hopper dredgers usually are very exhaustive, because a lot of specific movements
(each with it’s own requirements)have to be carried out. To tackle these movements, product packages have been developed.
