Trailing suction hopper dredgers (TSHD)

We design and build a variety of standardised and custom-built trailing suction hopper dredgers (TSHDs). A hopper dredger is a versatile dredger that unite dredging, transport and discharge in a single piece of equipment. Our TSHDs are ideal for many dredging jobs, such as land reclamation, port maintenance and aggregates dredging.

How does a hopper dredger work?

While slowly sailing, a hopper dredger trails a suction pipe off the side of the hull. At the entrance of a suction pipe is a draghead. This draghead collects the soil like the mouth of a vacuum cleaner. The slurry is pumped to the hopper and stored for transport. When full, the TSHD sets sail to the discharge location. Depending on the project specifications, the discharge takes place by opening the hopper doors, pumping the material to shore or by ejecting it using a rainbow installation.

Suitable projects

Hopper dredgers are allrounders by nature. It is a self-propelled, seagoing vessel and among other advantages a hopper dredger is capable of handling many different dredging projects. It can be put to work anywhere in the world. Also, it is the only type of vessel that dredges while sailing, making it the dredger of choice for operations in waters where tides and swell occur, and where interference with the movement of shipping cannot be allowed.
