PHOTO: Steel Cutting for Jan De Nul TSHD Trio

Jan De Nul Group has just released a photo from the steel cutting ceremony for three new trailing suction hopper dredgers (TSHDs) at Keppel Singmarine.

The vessels, ordered earlier this month, combine a shallow draught with high manoeuvrability, making them very suitable for working in confined areas, Jan De Nul said.

The TSHDs are in diesel-electric execution: all major drives (thrusters, dredge pump, jet pumps etc) are electrically driven and controlled by means of frequency converters.

As the new dredgers will frequently operate in estuaries and on rivers, or near the coast, and therefore near residential areas, Jan De Nul Group decided to limit the NOx emissions to a level far below the actual requirements, and to reduce other contaminants that are currently not regulated by IMO.

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.
