What is a cutter suction dredger?

A cutter suction dredger is a type of dredging vessel that is equipped with a rotating cutter head and a suction pipe. The rotating cutter head is used to loosen the sediment at the bottom of the body of water.

How Does a Cutter Suction Dredger Work??

Cutter suction dredgers work by using a rotating cutter head to loosen sediment at the bottom of a body of water. The cutter head is typically a circular wheel with a series of sharp teeth that rotate as the dredger moves forward.

What is the main purpose of dredging?

The main purpose of dredging is to deepen and maintain navigational channels, which allow ships and boats to reach their destinations more safely and efficiently. There are several dredging systems and types.

What is marina and harbor dredging, and why is it necessary?

Marinas and harbors are essential transportation centers for boats and ships that require regular maintenance to operate correctly. The accumulation of sediment, silt, and other debris in these waterways can cause shallow waters that impede navigation and pose safety risks to vessels.

Discharge: 14 inches
Main engine: Cummins NTA 855, 280 kW @1800 rpm
Reduction gearbox from the pump: Reintjes Laf 260
Dredge pump: 14/12 GG
Generator: Petter P600-2
Main generator/hydraulic: Cummins NTA 855M, 287 kW @1800 rpm
Jet-pump: Scania DS11, 220 kW
Pump: BBA CL 200/400
Cabin equipment: Production meter/flow meter/AC Dredging navigation/Sailer rt 2048 radio
Spud carrier hydraulic driven
Two hydraulic side winches (old type build)
Cutter: 130 kW
Spare cutter
Total fuel tank capacity: 2 x 7893 liters in side pontoons, 1 x 1046 liters day tank.

The Damen Cutter Suction Dredger is designed to work in a variety of water depths, and the 16-inch suction and 14-inch discharge capabilities make it suitable for a wide range of dredging applications. The main engine, Cummins NTA 855, provides the power to drive the dredging pump and the hydraulic system, which powers the cutter head and other equipment on board. The reduction gearbox from the pump, made by Reintjes, helps to optimize the performance of the dredging pump and ensure efficient operation.

The dredging pump, 14/12 GG, is a powerful piece of equipment that can handle a wide variety of materials, including sand, silt, and mud. The jet-pump, made by Scania, provides additional thrust to help move the dredged material through the pipeline.

The cabin equipment includes production and flow meters to help the crew monitor the dredging operation, as well as navigation and communication equipment to ensure the safety of the vessel and crew. The spud carrier is hydraulic driven, and the two hydraulic side winches make it easy to position and anchor the vessel during dredging operations.

Overall, the Damen Cutter Suction Dredger is a highly specialized vessel designed to handle the unique challenges of dredging operations, and the specifications of this particular vessel demonstrate its capability and efficiency.
