Company Profile

The number of people required for the operation of a dredger is influenced by factors such as the size, type, degree of automation, and complexity of the operation.

Generally speaking, small dredgers may require 3-5 people to operate, including the captain, engineer, dredging operator, etc.

Medium sized dredgers typically require around 5-10 people, and in addition to the aforementioned positions, they may also require material transportation and handling personnel, equipment maintenance personnel, etc.

Large, advanced and highly automated dredgers may have operators ranging from 10 to 20 people, or even more, to ensure the normal operation and monitoring of various systems and processes.

But this is just a rough estimate, the specific number of people still needs to be determined based on the actual situation.

Here are some detailed tutorials on the use of dredgers:
1. Preparation before operation:
-Conduct a comprehensive inspection of the mechanical equipment of the dredger to ensure that it is in good condition.
-Understand the water depth, seabed topography, soil conditions, etc. of the work area, and develop a reasonable work plan.
-Check the positioning system, dredging equipment, conveying system, etc. of the dredger to ensure its normal operation.
2. * * Positioning and anchoring * *:
-Use a positioning system to accurately locate the dredger in the work area.
-According to the homework requirements, throw out positioning stakes and lateral anchors to fix the position of the dredger.
3. * * Startup and Operation * *:
-Gradually start the various systems of the dredger according to the operating procedures.
-Adjust the dredging speed, depth, and conveying flow rate according to the actual situation.
-Pay attention to the working status of the dredger, including equipment operating parameters, dredging effect, etc., and make timely adjustments and optimizations.
4. * * Material Handling * *:
-According to the nature and purpose of the excavated material, choose the appropriate treatment method, such as transportation to the designated location, dumping or blowing.
-When handling materials, attention should be paid to environmental protection to avoid pollution to the surrounding environment.
5. * * Safety precautions * *:
-Operators must undergo professional training and strictly adhere to safety operating procedures.
-During the homework process, pay attention to observing changes in weather and sea conditions, and take corresponding safety measures in a timely manner.
-Regularly maintain and upkeep the dredger to ensure the reliability and safety of the equipment.

The above is a brief tutorial on using a dredger, and the specific operating methods and precautions may vary depending on the type of dredger, operating environment, and other factors. When using a dredger in practice, it is recommended to refer to relevant operating manuals and professional guidance.

          A cutter suction dredger is a dredging tool that uses a rotating cutter to loosen the soil on the riverbed or seabed, mixes it with cement to form mud, and then sucks the mud into the pump body through a suction pipe and sends it to the discharge area. It is mainly used for dredging in inland lake areas and coastal ports, suitable for excavating soil such as sand, sandy loam, and silt. During the construction of the cutter suction dredger, the dredging, transportation, and unloading processes can be completed continuously in one go, resulting in high production efficiency.
The main structure of a cutter suction dredger includes the hull, cutter, suction pipe, pump body, and discharge pipe. The cutter is a key component of a cutter suction dredger, usually installed at the bow or side of the ship. By rotating the cutter, the sediment at the bottom of the water is crushed and mixed with water to form mud. The suction pipe is used to suck mud into the pump body, which transports the mud to the discharge area through the discharge pipe.

 

 
 

The construction process of a cutter suction dredger is generally as follows:
1. Construction preparation: including the formulation of construction plans, survey of construction areas, equipment inspection and commissioning, etc., then positioning the ship and accurately positioning the cutter suction dredger in the construction area. According to the wind and flow conditions, set up the windward and upstream anchors in order to stabilize the ship's hull.
2. Lowering the cutter bridge: Lower the cutter bridge to the designated cutter position for excavation.
3. Soil conveying: The soil crushed by the cutter is transported to the designated mud receiving area through a high-power centrifugal mud pump and a discharge pipeline.
4. Construction monitoring: Real time monitoring of excavation depth, instantaneous water level, cross-sectional view of excavation trench or underwater three-dimensional map and other data to ensure construction quality and safety.
5. Moving ship position: According to construction needs, move the ship to the next construction area by retracting and releasing anchor cables and adjusting the position of the winch.
The specific construction process may be adjusted appropriately based on engineering requirements, soil quality, hydrology, and other factors. topic

The service life of a dredger is usually affected by various factors, such as manufacturing quality, frequency of use, maintenance and upkeep, and the severity of the working environment.

Generally speaking, if the manufacturing process of a dredger is excellent, its daily use and maintenance are appropriate, and the working environment is relatively good, its service life can reach 15-25 years or even longer.

However, if the dredger frequently operates with high intensity in harsh environments and is not maintained properly, its service life may be shortened, and some may require large-scale repairs or updates in about 10 years.

It should be noted that with the continuous progress and updates of technology, even if dredgers can still be used physically, they may be phased out early due to outdated technology, low efficiency, and other reasons.
