Dredge markets & applications

ECTMarine designs and supplies dredgers and dredging equipment for a wide range of applications, including waterway maintenance, reservoir dredging, mineral mining and coastal restoration.

Depending on the application, soil conditions and project requirements, ECTMarine offers cutter suction dredgers, plain suction dredgers and other specialized dredging solutions. Dredgers can also be customized to meet specific customer and project requirements.

Environmental dredging

Environmental friendly dredging means removing contaminated sediment layers at a minimal volume enlargement by reducing the necessary transport water to a minimum, at a minimum turbidity. During environmental dredging operations, managing turbidity is a major challenge. To safeguard nearby water bodies and limit the dispersion of contaminants, these techniques focus on removing sediment at high concentrations while keeping turbidity as low as possible. The ECTMarine Special environmental dredgers as AUGER dredge is designed to remove accurate thin layers so that the least possible quantities of material are dredged.

Water intake dredging

Industrial facilities and power plants depend on reliable water intake systems. Over time, sediment accumulation around intake structures can restrict water flow and affect operations.

ECTMarine offers cutter suction dredgers and plain suction dredgers for cleaning and maintaining industrial water intakes. The most suitable dredging equipment depends on sediment characteristics and project conditions.

River, canal and waterway dredging

The ECTMarine cutter suction dredger is ideal for river, canal and waterways marina maintenance. This type of dredger can excavate all kinds of soil, from sand and gravel to heavily compacted and hard materials such as clay, soft rock and even thin layers of hard rock. The cutter suction dredgers require anchors and winches to make sideways swinging motion. The dredger can be moved forward by a movable spud carrier system. If the river is close by sea with sufficient tide, a water injection dredger (WID) can be considered. A WID has minimal environmental impact, low carbon footprint, high production rate and low cost.

Marina and harbour dredging

The ECTMarine cutter suction dredger with swing ladder is ideal for marina maintenance. The swing cutterhead ladder is designed to work in narrow channels, marina and small projects.The swing dredger does not require anchors and cables witch prevents damage to yachts and (floating) jetties which is common with cable maneuvering dredgers. The dredger can be moved forward by a movable spud carrier system. Additional the quick dredge swing can be delivered in an environmentally friendly fully electric zero emission dredger. If the marina is close by sea with sufficient tide, a water injection dredger (WID) can be considered. A WID has minimal environmental impact, low carbon footprint, high production rate and low cost.

Hydrodam dredging

Hydroelectric dams are structures that use the power of falling or flowing water to generate electricity. Over time, sediment and other materials can accumulate in the reservoir behind the dam, reducing its capacity and affecting its ability to generate electricity. A dredger can be used to remove this accumulated material. ECTMarine’s cutter suction dredger or plain suction dredger are well suited for cleaning of the water intake of the hydro plant. Additional the cutter suction dredger can be delivered in an environmentally friendly fully electric zero emission dredger.

Water reservoir dredging

Over time, sand, silt and organic material can accumulate in water reservoirs, reducing their storage capacity. Reservoir dredging helps remove these deposits and maintain water storage capacity.

ECTMarine provides cutter suction dredgers and plain suction dredgers for reservoir dredging applications. Cutter suction dredgers are suitable for compacted and harder soils, while plain suction dredgers can be considered for loose, free flowing sediments such as sand and soft silt.

Mine tailings and industrial lagoon dredging

Mining operations produce large volumes of waste and debris referred as “tailings” that end up at the bottom of containment ponds and lagoons. It is essential to remove sediment in mining ponds to maintain water capacity. The ECTMarine cutter suction dredger is ideal for mine tailing dredging if the material is a hard soil type. If the material is free floating a plain suction dredger can be considered.

Sand and gravel dredging

Sand mining involves extracting sand and minerals from the seabed by dredging. Sand is the planet’s most mined material. The ECTMarine cutter suction or plain suction dredger are ideal for sand mining. If the material is free floating a plain suction dredger can be considered. The cutter suction dredger is the best solution if it’s a hard soil type of material.

Mineral mining dredging

Mineral mining dredging involves extracting valuable minerals from underwater deposits, including mineral sands and other mineral resources. Dredged material can be transported to stockpiles or processing facilities for mineral separation.

ECTMarine offers cutter suction dredgers and plain suction dredgers for mineral mining applications. Plain suction dredgers can be considered for loose, free flowing materials, while cutter suction dredgers are suitable for harder soil conditions that require mechanical excavation.

Coastal restoration and land reclamation

Coastal restoration and land reclamation projects focus on restoring eroded shorelines and creating new land. These activities often involve dredging and transporting sand or other materials.

ECTMarine offers cutter suction dredgers for coastal restoration and land reclamation projects. Plain suction dredgers can also be considered when soil conditions allow.

For trailing suction hopper dredgers, ECTMarine offers solutions ranging from design and equipment packages to complete vessels.
