River Dredging and Deepening

River dredging is a form of river restoration and river maintenance. Over time, sand, silt and debris (branches, logs, waste) flow downstream. This is a natural phenomenon, which happens due to weathering, erosion and rivers carrying sediments. If not maintained, the materials accumulate and create a blockage. Consequently, this restricts natural river flow and makes the waters very shallow. As a result, rivers become inaccessible to larger ships. Additionally, during heavy rain season, restricted river flow can cause flooding. Flooding may result in major property damage, have negative impact on local businesses, and even be life threatening.

River dredging is therefore necessary to maintain natural river flow and appropriate water depth to minimize risk of potential disasters.

River Dredging Equipment

Dredging equipment for river dredging can include cutter suction dredgers depending on the conditions on site. Some of the factors to consider are river currents, water depth and materials to be dredged. In addition to different dredger types and sizes, we offer dredging equipment customization (e.g. increasing swing length, extending dredging depth) according to project requirements.

Our standard dredger series includes one truck transportable Cutter Suction Dredgers. Compact cutter suction dredgers allow for easy and economical dredger transport to the project site. In addition to this, the dredger can be easily removed from water and stored for later use.

SETTLING POND DREDGING

Pond dredging and cleaning is a type of maintenance dredging. Over time, settling ponds, holding ponds and lagoons at industrial plants may accumulate sludge, silt and sediments. Consequently, accumulated materials reduce effectiveness and water storage capacity of the settling ponds. As a result, productivity and efficiency of the industrial plant is reduced. Regular pond dredging projects can ensure ongoing efficiency of the business.

Pond Dredging Equipment

Pond dredging may involve petrochemical sludge, fly ash pond (produced by burning coal) or desliming ponds in mining operations. Dredging of a pond can be performed using cutter suction dredgers when the materials have settled over a longer period of time and have become compact. Our dredgers are compact, and can be easily transported and operated in remote locations and ponds of varying sizes.

Reservoir, Lake and Dam Dredging

Reservoir dredging, lake dredging and dam dredging is used to restore these water sources to their full capacities. Throughout the years, hydro-power dams, reservoirs and freshwater lakes retain and accumulate quantities of sandy deposits in or behind them. As a result, sediments diminish the total water reserve capacity of the plant. This is called sedimentation. If not maintained, sediments can reach the water outlets and thus, cause severe wear damage to the turbines. Therefore, regular dredging is required.

Reservoir dredging equipment

Type of dredging equipment used for reservoir dredging, lake dredging and dam dredging depends on a variety of factors on site. Namely, water depth, accessibility and type of material, play an important role in the decision making process. Sediments in lakes and reservoirs mainly consist of clay, silt and varied sizes of sand. It can also contain chemical precipitates, organic debris and often, combinations of these. Therefore, it is vital to analyze project location and requirements before selecting the type of dredger for the project.

Our standard dredger series includes one truck transportable Cutter Suction Dredgers. Compact ECO dredger design allows for easy and economic dredger transport to project site. In addition to this, the dredger can be easily removed from water and stored for later use.

WATER INTAKE DREDGING

Water intake dredging is used to retain cooling capacity and overall efficiency of industrial plants. Large industrial plants such as petrochemical plants, power plants and desalination plants use water intake channels for cooling purposes. These water intakes are commonly connected to lakes, rivers, canals or the open sea. Due to factors such as weathering and erosion, sediments are carried and deposited in the mentioned water bodies. Therefore, in order to avoid their entering the industrial plant, water intakes are equipped with sand traps or screens.

However, over time, sediments can accumulate at the trap. As a consequence, less water can enter the industrial plant, which limits its cooling capacity and results in reduced overall efficiency. Therefore, regular maintenance dredging is needed to keep the water basins clean and the capacity of the industrial plant at its maximum.

Water Intake Dredging Equipment

Water intakes can often be difficult to access and may require precise dredging. Our cutter suction dredger is suitable in cases when sediments have accumulated over a longer period of time and have become compact. It features a compact design, making them easy to transport, launch and store for later use.

MINE TAILING REMOVAL AND DREDGING

Mine tailing dredging is used for cleaning up tailing ponds, removing leftover chemicals or capturing leftover valuables. Mine tailings consist of crushed, finely ground rock and waste products from mineral processing operations in mining. Due to chemical components, storage and handling of tailings has become a major environmental issue worldwide. Therefore, mine tailing dredging provides an efficient solution to clean up mine tailings ponds, especially when tailings contain dangerous contaminants.

Mine Tailing Dredging Equipment

Mine tailing dredging equipment depends on the nature of the materials to be dredged. When mine tailings contain leftover chemicals, they must be dredged and disposed of with precision. When more power is required due to more compact, harder materials, our cutter suction dredgers are the more appropriate equipment choice.

ENVIRONMENTAL DREDGING

Environmental dredging describes clean up projects aimed at improving the environment. Rivers, lakes, lagoons and major industrial ports and harbors are often confronted with severe environmental problems of contaminated soils. Contaminants in water endanger both marine and human life, as well as the surrounding environment. Therefore, they need to be removed in a controlled manner minimizing the spreading of the pollutant into the surroundings. After environmental dredging of contaminated soils, they are pumped ashore for further processing, dewatering, storage or disposal.

Our dredgers are the equipment of choice to dredge polluted soils. The submerged dredge pump in combination with the cutter excavating tools provide efficient dredging performance avoiding dispersion of pollutants. Additionally, we designed the Cutter Head, with environmental protection and high efficiency in mind.

Environmental Dredging Equipment

Environmental dredging requires precise dredging with low turbidity to avoid the spread of contaminants.

CANAL AND CHANNEL DREDGING

Canal dredging and channel dredging are important to maintain efficient navigation, irrigation, power sources, commerce and businesses running smoothly around the world. Similarly to rivers, sediment and debris can gather in the bottom of these water sources. As a result, waterways become shallow, which can disturb traffic and other vital activities, if not maintained through dredging.

Canal and Channel Dredging Equipment

Our cutter suction dredgers can be used for canal dredging and channel dredging, depending on the conditions on site. Our dredgers are compact – one truck and one container transportable. The compact design allows for efficient operation on remote project sites, as well as narrow canals and channels. Additionally, we offer to customize dredging equipment according to the specific canal and channel dredging project requirements. As an example, customization can include extension of dredging depth or an increase in cutting power.
