Auger & Cutter Dredgers For Any Project.

Dredge Yard continues its mission in being the leading manufacturer of small to medium sized professional dredgers. The new Auger dredger 200 (8inch) and Cutter Suction Dredger 250 (10inch) ensure high efficiency and durability. Additionally, Dredge Yard always offers very versatile dredgers. In accordance to this, dredger 200 and 250 design features interchangeable components. Thus, each dredger can be equipped with a cutter head (with replaceable teeth), auger head or plain suction head. Therefore, these dredgers are not only compact, durable and good-looking, but also suitable for a wide variety of dredging and mining applications under all conditions.

In addition to its versatility, the new Auger, Cutter and Plain Suction dredgers have been optimized to increase dredge performance and decrease operational costs. How? Read on.

Underwater Dredge Pump

The dredged material is pumped by an underwater dredge pump, which is driven by a hydraulic motor and mounted on a rigid bearing assembly and shaft. As a result, the pump can have a higher pumping flow and of a higher density mixture. Therefore, overall, an underwater dredge pump design offers higher production than a dredge pump mounted in the pontoons.

In addition to this, the control cabin is equipped with all necessities to ensure the operator’s safety and comfort. For example, the cabin is supplied with noise and vibration reduction, ventilation, windshield wipers and an adjustable chair, to name a few. Moreover, air conditioning or a heater is included depending on the geographical location of operation.

Propulsion

All of the dredgers 200 and 250 are self-propelled with two hydraulic thrusters provided only by the best, first-class European brands. As a result, the dredgers are easily maneuverable without any involvement of tugboats or other support. Furthermore, to ensure mobilization support, the dredgers are equipped with tiltable spuds, which can be manually tilted and secured to the deck.

Finally, another important characteristic to highlight, is that the new dredgers 200 and 250 accommodate higher fuel tank capacity. Therefore, the number of necessary refueling intervals for continuous operations is reduced, which allows uninterrupted project work.

Below you can review some of the specifics of Auger Dredger 200 and Cutter Suction Dredger 250.

Cutter Suction Dredger ECO 200 to UAE

Dredge Yard delivered a multipurpose cutter suction dredger ECO 200 to a real estate developer in the United Arab Emirates for the reshaping and maintenance of existing islands. The ECO 200 dredger will be used for connecting some of the islands and deepening the sea entrance between the islands. Due to current and erosion, the coast of the islands changes with the years. For this reason, it is necessary to perform periodical maintenance to keep the shape of the islands and maintain a pleasant beach. In some areas the beach is flooded by new soft types of sand that makes it difficult for visitors to enjoy the beautiful clear waters of the Emirates. In other places it is necessary to maintain the water depth for yachts and work boats to visit the area. Dredging is the only way to maintain artificial and natural shaped islands and beaches.

The ECO 200 Cutter Suction Dredger

The ECO 200 dredger is equipped with a heavy-duty cutter head and underwater dredge pump for high performance and for pumping a high-density mixture of sand. The high dredging performance will speed up the dredging process to limit the time involved in maintenance. For easy mobilization the dredger is provided with two hydraulic propulsions. The ECO 200 Cutter Suction Dredger can pump the sand up to 1500m and dredge up to 6 meters depth. One of the advantages of the ECO dredger is the use for dredging in small and shallow areas that are difficult for bigger dredgers to enter. The draft of the ECO dredger is only 0.7m. This multipurpose cutter suction dredger is delivered completely assembled and launched into the water by mobile crane.

Euro Dredger 450 now available

The Euro Dredger 450, built in the Netherlands, has been successfully launched and is now available for delivery. The Euro Dredger 450, also known as Dredge Yard’s CSD450, is a cutter suction dredger with a discharge pipe diameter of 450mm.

The Euro Dredger 450 is the first cutter suction dredger resulting from the partnership between Dredge Yard and Neptune Shipyards in The Netherlands. Both companies joined forces to enable the building of this multi-purpose cutter suction dredger that is suitable for dredging, soft and medium compacted sand and other sediments up to a dredging depth of 10 m on inland waters, rivers and lakes.

Specifications of the Euro Dredger 450

The Euro Dredger 450 has a total installed power of 866 kW. It consists of 3 dismountable pontoons fixed by a rigid coupling system inside the pontoon. It is designed to be disassembled easily and to be transportable by road.

The high performance dredge pump – entirely developed and manufactured by Dredge Yard – is mounted directly onto the gearbox to save space and reduce the weight, and it is driven directly by a 634 kW diesel engine. A hydraulic power pack of 232 kW is fitted on the main pontoon to supply hydraulic power to the cutter head, winches and spud hoist cylinders.

The hydraulically driven cutter head – developed by Dredge Yard – has exchangeable cutter teeth that come in three types: pick points, narrow and wide chisels. The blades of the cutter head are double curved to allow for a smooth mixture flow through the cutter and into the suction mouth.
