Why choose a Plain Suction Dredger?

Our main benefits

  • High production capacity at deep dredging depths

    The heavy-duty dredge pump is located on the suction ladder under water. This will allow the pump to have a higher pumping flow and a mixture of a higher density resulting in more production than a dredge pump mounted in the pontoons. The vacuum limit will not be reached with an underwater dredge pump especially when dredging at a depth of 15 meters or more.

  • Six winches operation

    During dredging the dredger is moved slowly forward by a set of winches. The dredger consists of six winches, two forward side winches, two rear side winches, one ladder hoisting winch and one suction pipe hoisting winch.

  • Low Consumption

    Because the pump speed is variable, and the dredge pump is underwater this allows the system to be more efficient on the suction dredger. The pump can be used at the right speed according to the discharge pipe length and because of the underwater pump, the mixture density is higher. This results in a low fuel consumption per cubic meter production.

  • Easy mobilization in the water

    The plain suction dredger is supplied with high efficiency hydraulic propulsion of European brand. This dredge propulsion will allow the dredger to moving around the dredging area.

  • Cabin with all necessaries

    Dredge Yard plain suction dredge cabin is provided with Air conditioning or heater, depends on geographical location of operation. Also, the cabin is supplied with noise reduction, ventilation, rain/screen wiper, adjustable chair, mirrors, and lock door. To minimize the vibration the cabin is mounted on vibration reduction. The cabin is placed in the middle of the suction dredger and above the center pontoon to allow for a good overview of all operation.

  • High production

    The suction mouth is a balloon shaped screen at the end of the suction pipe. The screen is to avoid pump blockage by boulders and debris. Special care has been taken to decide the size of screen considering pump’s capacity. Jet nozzles are located around the screen to loosen the material and increase the material mixture flow to enhance production.

  • Reliable Brands

    Dredge Yard’s plain suction dredgers are only provided with first class brands. All brands are European, USA, or Japan made. All equipment is from reputable manufacturers with proven designs. The steel components are manufactured under the supervision of Dredge Yard and all dredge components have undergone a detailed inspection.

  • Optimized production on project basis

    Due to the hydraulic drive of the dredge pump, the plain suction dredger can pump mixture of silt, sand and sediments to different discharge pipe length. The speed of the pump can be adjusted to get the right flow and pressure.

Types of ECO Plain Suction Dredgers

A suitable solution for each project

ECO 200 Plain Suction Dredger

Plain Suction Dredger design of ECO 200 Plain Suction - Dredge Yard

The ECO 200 Plain Suction Dredger is especially designed for dredging at depths up to 20 meters deep.

Main features

All ECO Plain Suction Dredgers come with

Suction head

The suction mouth is a balloon shaped screen at the end of the suction pipe. This screen avoids pump blockage by boulders and debris. Special care has been taken to decide the size of screen considering the pump’s capacity. Jet nozzles are also located around the screen to loosen the material and increase the material mixture flow to enhance production. A jet pump, located on the hull, supplies the jet water.

Dredge pump

The high efficiency underwater dredge pump is mounted on a rigid bearing assembly and shaft. It is driven by a hydraulic motor.

Power

Our ECO Plain Suction Dredgers are supplied with a diesel driven hydraulic power unit that is reliable and efficient.  An air radiator is used for cooling the diesel engine and hydraulic system.

Dredge system

The suction ladder is stiffened to make it suitable for extension of the plain suction dredger to a different depth. The ladder is hoisted by a hydraulic operated winch. That winch is mounted on the pontoon in front of the cabin. Further, the suction pipe ladder is also hoisted with a hydraulic winch. A wear resistant, thick and reinforced rubber hose is assembled between the ladder and the pontoon. Four hydraulic winches are provided for the back and forth movement of the dredger.

Pontoons

The base of our ECO Plain suction dredgers consists of one center pontoon and two side pontoons. These pontoons are stiffened with longitudinal and cross bars. For hoisting the suction head, dredge pump and ladder, a gantry with sheave assembly is placed between the two pontoons. The operating cabin is mounted on the center pontoon and supplied with air-conditioning or heater.

Options for the ECO Plain Suction Dredgers

To customize your plain suction dredger

Hydraulic propulsion

For the easy movement of the Plain Suction dredger a compact and efficient hydraulic Thrusters can be mounted at the back of the side pontoons. Steering is done from the operating cabin by a joystick.

Extension of dredging depth

The standard dredging depth can be extended to meet the requirement of a certain project by adding an additional adapter between the dredge pump and the Plain Suction head system.

Cutter Suction Dredger

The dredger can be modified to cutter suction dredger by replacing the ladder front piece from auger head to cutter head, changing the orientation of the winches, placing spuds and spud hydraulic cylinders. All those changes can be supplied by Dredger Yard and they are all plug and play system.

Auger head dredger

The dredger can be modified to auger head dredger by replacing the ladder front piece and changing the orientation of the winches. The necessary modification parts can be provided by Dredge Yard for installation on the dredger at any time.

Automation & control

Automation control system can improve the overall performance of the dredger and makes the dredging process more visible. Several types of dredging automation and controls can be provided depending on the level automation and project requirements.
