1. What is a cutter suction sand dredger?

The cutter suction sand dredger is a kind of ship equipment specially used for dredging and dredging in shallow water areas such as rivers, lakes and shallow seas. It is mainly composed of hull, cutter suction device, sand suction pump, power system and pipeline and other parts.

By extending the sand suction pipe into the bottom of the water, the cutter head breaks the sand and mud layer, and then suck the mixture of water and sand slurry into the pump and deliver it to long distance.

2. What’s the characteristics of the cutter suction sand dredger?

The cutter suction sand dredger has the characteristics of high operating efficiency, good desilting effect, and easy operation. It is an indispensable equipment in the fields of water conservancy projects, river channel management, and port construction.

3. Description of OCEAN PUMP CSD dredger:

• How does the dredger work?

The cutter suction dredger of Taian Ocean Pump Industry Co., Ltd. is equipped with a mud pump and a mud suction device. When dredging, the cutter head is used to loosen the river bottom soil, and then a mud pump is used to suck the mud from the mud suction pipe and send it to the destination through the discharge pipe. Onshore or discharged into mud barges for transport. Cutter suction dredgers are generally non-motorized and mostly used for dredging and filling projects, and are suitable for excavating river bottoms with loose soil such as sandy soil and silt. A dredger with a toothed reamer can also dig harder gravel clay.

• How does the cutter suction sand dredger move?

When dredging, one of them is inserted into the river bottom as a positioning pile, and the dredger is pulled by the anchor cable, and the positioning pile is used as the center to swing left and right for dredging. When moving forward, it is like walking on two legs, using another steel column to replace the pile alternately, and the reamer advances in a fan shape during the dredging process.

• Dredger features and application:

During the construction of the cutter suction dredger, dredging, mud conveying and mud unloading are all integrated and completed by themselves, with high production efficiency and low cost. OCEAN PUMP Cutter suction dredgers are widely used for construction in inland rivers, lake areas and coastal ports, and are a major type of existing dredgers. There are two steel columns at the stern of the dredger.

4. Successful cases of CSD dredger to Malaysia.

4.1 Background of customer procurement and the dredger description.

This cutter suction dredger is a large offshore cutter suction dredger delivered to Malaysia. The customer intends to use this dredger at sea, so the requirements for hull design are high. The hull is 2.2 meters high, 33 meters long and wide 7 meters, and the shipping weight of the whole ship reaches 172 tons.

This is the second offshore cutter suction dredger in Malaysia. Most of the others were delivered to customers in Africa and Southeast Asia. This cutter suction sand pump uses a 16-inch sand pump, but the flow rate reaches 3800 cubic meters, the output is high, and it can easily pump more than 600 cubic meters of sand per hour.

4.2 What’s the feedback from the customer?

The dredger was well received by the customer, and the customer recommended our product to other customers after using our equipment for one month. The customer said that the dredging work will be carried out in February next year, and he will order one at that time. Dredging operations with our cutter suction dredgers. Our integrity is to bring high-quality and efficient dredging solutions and equipment to customers!

4.3 Detailed configuration of the cutter suction dredger:

The cutter suction dredger has a pumping depth of 15 meters and also works in shallow sea areas. The dredger directly pumps sand into the sand transporter. Most of the cooperation with it is a large offshore belt sand transporter with a capacity of 5,000 cubic meters. Therefore, only when the sand pumping capacity is high can the sand carrier cooperate with customers. The diameter of the ship’s reamer reaches 1.6 meters, so it provides a guarantee for the high-concentration sand pumping of the sand pump. Please see detailed configuration:

• Hull design:

Hull size = length, width and height 33m*7m*2.2m (multi-body structure)

Ship plate thickness: bottom plate 10mm, side plate 8mm, panel 6mm, all are CCS marine steel plates

The designed pumping depth is 15 meters, and the designed sand discharge distance is within 100 meters.

• Diesel engine and sand pump

The main engine WEICHAI Power 8170-601KW drives a 16-inch high-chromium alloy pump

Auxiliary engine WEICHAI Power WD618-294KW drives the hydraulic system and power consumption of the whole ship

16-inch high-chromium alloy pump: 18-inch inlet, 16-inch outlet, 50-meter head (customer will replace high-power diesel engine cofferdam later)

• Hydraulic reamer

The diameter of the reamer is 1600mm, the teeth can be replaced, and it is made of wear-resistant alloy. complete hydraulic system
