IADC: 1DH Model on Transport and Sedimentation Inside TSHD

Image source: IADC

The International Association of Dredging Companies (IADC) has just released a very interesting article named 1DH Model Predicts Transport and Sedimentation Inside a Hopper.

Trailing suction hopper dredgers (TSHDs) are commonly used in the dredging industry at a wide variety of maintenance, land reclamation and maritime construction projects.

During trailing suction dredging the TSHD trails dragheads over the seabed to excavate it. The loosened bed materials like sand, clay or gravel together with surrounding water are hydraulically sucked up by pumps through the trailing suction pipes. This mixture is subsequently discharged into the ship’s cargo hold called hopper.

There the suspended sediment disperses and settles throughout the hopper to form a sediment bed layer at the bottom.

Simulation of the sedimentation processes in hoppers is of great interest to provide predictions of how efficiently the incoming sediment is retained in the hopper, stated the article.

A prediction model developed by Van Oord engineers is introduced to accurately and easily predict the overflow of sediments.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
