Mud Cat Dredgers Operating in Tigris and Euphrates Rivers

Multiple amphibious, multi-function dredgers from Mud Cat are operating in Iraq to clean various dams and barrages that are positioned along the Tigris and Euphrates Rivers.

Iraq’s Ministry of Water Resources (MWR) purchased the MFDs to remove accumulated silt, sand and vegetation at each dam’s basin.

By performing regular dam maintenance, Iraq’s MWR can maintain the designed water levels at the dams to prevent structural components from being compromised.

The two rivers have a confluence near Al Qurna to form the Shatt al-Arab waterway in southern Iraq, which empties into the Persian Gulf. In this area, an extensive marshland environment is present, making it difficult at times to navigate when water levels are low.

The Tigris and Euphrates Rivers are heavily dammed to provide water for irrigating in the semi-desert regions bordering the river valleys as well as creating a source for hydroelectric power. Damming has also been important for averting floods in Iraq, to which the Tigris River has been historically prone following the snowmelt in the Turkish mountains around April.

MUD CAT MFD-1000 AMPHIBIOUS MULTI-FUNCTION DREDGER

The Mud Cat MFD-1000 is an amphibious, multi-function, self-launching, versatile dredging machine that is one-truck transportable and can easily operate in many different environmental clean-up projects.

It is capable of moving and dredging through shallow water areas where other single purpose dredging machines cannot operate.

The MFD-1000 is designed for maximum productivity. It comes furnished with a single-piece hull built to ABS River Rules, a modern and comfortable cabin, easy-to-use joystick controls, a heavy-duty industrial excavator arm, and an up-to-date diesel engine.

NO CRANE NEEDED FOR LAUNCHING

The MFD-1000 is capable of walking from shore to bodies of water without the need for cables, winches, or cranes, reducing additional expenses for mobilization. Two pivoting rear steel spuds and a heavy-duty excavator arm maneuver the amphibious dredger on dry ground with ease.

While in operation, two front round stabilizers made of steel help support the dredger when it excavates up to 19.5 feet (5.92 m) with an 180º swing. The two front stabilizers have a maximum depth of 12 feet (3.6 m) and the two rear pivoting spuds have a maximum depth of about 17 feet (5.4 m). Two steel side tanks mounted to the hull provide additional buoyancy and stability when in operation.

The MFD-1000 is also a self-propelled dredger with a single 24-inch (609 mm) hydraulic multi-directional prop-drive system, making it very maneuverable in the water system.

Mud Cat engineers included the industrial heavy-duty excavator arm in the MFD-1000 design so that it can attach to multiple interchangeable tools, such as an excavator bucket, an articulating clamshell bucket, a weed rake, a pile driver and a submersible cutter suction hydraulic pump, making the dredger more versatile for various light-duty and heavy-duty projects.

Quick-release hydraulic couplings on the excavator arm allow operators to quickly change the tools without losing valuable operating time.

Liquid Waste Technology, which makes the Mud Cat dredger line, selected a Caterpillar 300 HP C.9 Tier 3, turbocharged and intercooled diesel engine and an 8-inch (203 mm) submersible cutter suction pump attachment to help meet MWR’s pump production requirement.

The hydraulic cutter suction pump, designed at 3600 GPM @ 75 feet TDH (817 m3/h @ 22.86 m), handles up to 3-inch (76 mm) solids and is capable of pumping over 1650 feet (500 m) in a 10-inch (254 mm) pipeline.
