Damen: Plug and Play Trailing Pipe for Russian Pontoon

Damen has delivered a complete trailing pipe including submersed dredge pump to a Russian pontoon. The multifunctional pontoon “Litsa” has been turned into a performing dredger overnight as Damen delivered an entirely prefabricated system.

The pontoon is winning sand and simultaneously loading barges which continue to appear alongside. A hyper efficient ongoing dredge action – required by the looming winter.

The Ø 650 mm trailing pipe mines sand at max -28 m depth, where gas pipes are to be cleared. The starboard trailing pipe is fitted out with a submersed dredge pump, directly driven by a 700 kW electric motor. The sand is pumped over deck to a discharge spreader located at portside. An uninterrupted carousel of barges sails alongside to be filled continuously. The sand production is closely monitored using the density and flow meter on board, and using the low mixture overboard connection.


The entire Damen dredging system has been designed as a “plug and play”-one. This means that the installation of the various elements did not need dry-docking nor serious constructional work. The gantries, winches and swell compensator all were equipped with their proper foundation – they were welded on deck and installation was completed. The trailing pipe elbow slides in-board and does not need a slide flange construction. The discharge spreader has its own winch and foundation making it into a complete kit.


Furthermore, a number of easily transportable containers were supplied, filled with vital gear. One 30’ container houses the diesel-electric set with frequency drive for the submersed dredge pump motor. A 20’ container houses the diesel driven jetwater pump, which feeds pressurized jetwater to the drag head. Another 20’ container was equipped with the diesel-hydraulic installation, which controlled the gantry cylinders, the winches, the swell compensator and the dredge valves. The swell compensator bottles were accommodated in this container as well.

At the bridge, a control panel was mounted with all controls of the diesels and hydraulics. Separate screens were fitted to show the trailing pipe position, the dredge pump performance and the dredgers and drag heads position, all using Damen software.


All in all the project was a special “plug and play”-one – a necessity due to its operating location. The pontoon works in Northern Russia near the island of Nova Zembla, where the summers are very short and all dredging activity has to be completed before the ice gets in again. The mission has been successfully completed using the Damen dredging equipment.

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.
