Environmentally Friendly solution: Adaptive Auger Head

Adaptive auger head auger dredger

At Dredge Yard, we pay special attention to high efficiency and innovative solutions. We do this, to achieve lowest equipment prices, operational costs and minimal impact on the environment. Sustainability and green dredging solutions become increasingly important, as climate and environment are rapidly changing and must be protected. In accordance to this, our team created an innovative dredging solution, which protects the environment – the adaptive auger head. 

Specifications

The adaptive auger head has two retractable visors placed on the front, and the backside of the auger head. The visors move in and out, according to the shape of the seabed and the depth. This automatic visor movement is enabled by the hydraulic arrangement and pressure settings. See the video below for a thorough explanation of how the adaptive auger head works. 

Benefits of the adaptive auger head

The adaptive auger head achieves a variety of environmental and economic benefits, due to its automatic visor movement along the ground when dredging. Some of the benefits include:

  1. More production of sand in less time. The adaptive visors create a strong suction vacuum by continuously following the ground, which achieves high production rates.
  2. Much less turbidity than with conical (basket) cutter head types. This is achieved due to adaptive visors, which control the material spillage. Low turbidity is an especially big advantage when dredging in contaminated areas, as it protects the environment. 
  3. The adaptive system saves marine life by protecting animals from entering the suction system in the dredger.
  4. This system accurately removes only the necessary layer and ensures an even surface at all depths. Therefore, necessary materials are not removed from the ecosystem.
  5. It is suitable for unmanned dredging, because adaptive visors automatically adjust with the ground. This makes the system very useful for remote controlled dredgers, which operate in areas that are risky for operators. 

Remediation / environmental dredging

Environmental Dredging Landscape

The adaptive auger head is an especially suitable solution for environmental dredging. As mentioned, the adaptive visors protect the marine life from getting trapped in the dredging system. Additionally, they cause minimal to no turbidity. This characteristic is vital for the ecosystem, especially when contaminated soils are involved. Some of the other advantages of using the adaptive auger head system in environmental or remediation dredging are discussed below. 

  1. Adaptive auger head improves cleanup operations that are specifically aimed at removing contaminated sediments. This is especially important, as contaminants can endanger marine and human life.
  2. Remediation dredging means that the thinnest layers possible are accurately removed. As a result, the least possible quantities of contaminated material are dredged.
  3. Contaminated sediments pose a big risk to human health, the environment and may limit the use of many water bodies. However, treatment of contaminated sediment is costly and secure disposal areas are limited. Therefore, precision dredging offers a viable solution, as it removes the smallest amount possible. 
  4. The adaptive visors enclose the area being dredged. In this way, they prevent sediments from drifting into the surrounding waters. 

Other applications for the adaptive auger head

Aside from environmental dredging, the adaptive auger head can be used for a variety of applications. For example, it is a useful tool in river and canal dredging, water intake cleaning, harbor maintenance and more. 

Overall, not all types of dredging or maintenance have to be very precise. However, certain projects demand environmental society clearance. In such cases, the adaptive auger head adds immense value to your product in terms of both – economic reasons for you and protection of the environment. We offer Auger dredger ECO 200, which features our adaptive auger head system. Additionally, the adaptive auger head can also be purchased separately, in order to upgrade your existing dredger.
