Hopper dredging

More than 100 years ago, IHC’s Kinderdijk shipyard built the first trailing suction hopper dredger (TSHD). Since then, the group has developed around 400 highly efficient, innovative and cost-effective, self-propelled standardised and custom-built TSHDs for its broad customer base.

Trailing suction hopper dredgers are used for the excavation and transportation of materials such as sand, gravel and silt. They can be found operating around the world, on projects including harbor construction, channel maintenance, coastal protection, beach re-nourishment and land reclamation.

The dredging system of a TSHD typically consists of the trailing suction installation for excavation and slurry creation, dredge pumps for hydraulic transportation, a hopper for storing soil during transportation, discharge installations for unloading the slurry, dredge line components that connect the complete system, and automation systems for controlling and monitoring of the dredging process.
