Product Description

Trailing suction hopper Dredger is a ship that has a full sailing capacity used to maintain navigable waterways, deepening the maritime canals that are threatened to become silted, to construct new land elsewhere or to replace sand eroded by storms or wave action on the beaches. This made possible by large powerful pumps and engines able to suck sand, clay, silt and gravel.

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.
