Adaptive auger head introduced by Dredge Yard

Dredge Yard adds another innovative dredging solution to their portfolio: the adaptive auger head. The adaptive auger head has two retractable visors placed both on the front and backside of the auger head. The visors move in and out, according to the shape of the seabed and according to the depth. A hydraulic arrangement and pressure settings enable this automatic visor movement. The adaptive auger head achieves several benefits by following the ground during dredging.

The video below explains the working and advantages of our adaptive auger head.

 

Benefits of the adaptive auger head

  1. More production of the sand in less time. The adaptive visors create a strong suction vacuum by continuously following ground.
  2. Much less turbidity than with conical (basket) type cutter heads. Because the adaptive visors control the material spillage. This is a big advantage when dredging in contaminated areas.
  3. The adaptive system saves marine life by protecting animals from entering the suction system in the dredger.
  4. This system ensures an even surface at all depths.
  5. It is suitable for unmanned dredging. The adaptive visors automatically adjust with the ground. That makes them very useful for remote controlled dredgers that work in areas where environment is risky for operators.
  6. The solution perfect for environmental dredging. The adaptive visors keep marine life from getting trapped in the dredging system. They also cause low or even zero turbidity.
  7. Low investment.

Remediation / environmental dredging

The adaptive auger head is, as mentioned above, perfect for environmental dredging or remediation for a number of reasons:

  1. Adaptive auger head supports cleanup operations that are specifically aimed at removing contaminated sediments that can endanger marine and human life.
  2. Remediation dredging means that the thinnest layers possible are accurately removed so that the least possible quantities of contaminated material are dredged.
  3. Treatment of contaminated sediment is costly and secure disposal areas are limited, precision dredging offers a viable solution. Contaminated sediments can be a big risk to human health, the environment and it may limit the use of many water bodies.
  4. The adaptive visors enclose the area being dredged and prevent sediment from drifting into the surrounding waters.

Other applications for the adaptive auger head

The adaptive auger head is not only suitable for environmental dredging, but for a variety of applications. It is also useful in river and canal dredging, water intake cleaning and dredging and marina or harbor maintenance.

Not all types of dredging or maintenance have to be very precise. But certain projects demand environmental society clearance. In such cases, the adaptive auger head adds value to your product, making it very versatile and usable in any project.

ECO 200 dredgers available in stock

Dredge Yard, in continuation of its program for building medium size and small dredgers in stock, is building more ECO 200 dredgers in 2018. The new ECO 200 dredgers are optimized with improvements to increase dredge performance and operations, meeting the demand of the market. The dredger can be equipped with a cutter head, auger head or plain suction head. These diverse options make the ECO 200 a very versatile dredger for many different dredge applications.

Underwater dredge pump

Material is pumped by an underwater dredge pump, which is driven by a hydraulic motor and mounted on a rigid bearing assembly and shaft. This will allow the pump to have a higher pumping flow and a mixture of a higher density, resulting in more production than a dredge pump mounted in the pontoons.

The control cabin is equipped with all necessaries like air-conditioning system or heater, noise reduction all around, ventilation on top, screen wipers and an adjustable ergonomic chair.

Propulsion

All ECO 200 dredgers are self-propelled with two hydraulic thrusters of a European brand. This will help move the dredger around without any involvement of a tug boat. To support the dredger in mobilization, tiltable spuds are provided that can be manually tilted and secured to the deck.

Moreover, the new ECO 200 dredger accommodates more fuel tank capacity to reduce refueling intervals for continuous operations.

We have now one ECO 200 Auger Dredger and one ECO 200 Cutter Suction Dredger available to deliver immediately. Contact us to view the dredgers.

Dredge Yard delivers multipurpose cutter suction dredger

Dredge Yard delivered a multipurpose cutter suction dredger ECO 200 to a real estate developer in the United Arab Emirates for the reshaping and maintenance of existing islands. The ECO 200 dredger will be used for connecting some of the islands and deepening the sea entrance between the islands. Due to current and erosion, the coast of the islands changes with the years. For this reason, it is necessary to perform periodical maintenance to keep the shape of the islands and maintain a pleasant beach. In some areas the beach is flooded by new soft types of sand that makes it difficult for visitors to enjoy the beautiful clear waters of the Emirates. In other places it is necessary to maintain the water depth for yachts and workboats to visit the area. Dredging is the only way to maintain artificial and natural shaped islands and beaches.

The ECO 200 Cutter Suction Dredger

The ECO 200 dredger is equipment with a heavy-duty cutter head and underwater dredge pump for high performance and for pumping a high-density mixture of sand. The high dredging performance will speed up the dredging process to limit the time involved in maintenance. For easy mobilization the dredger is provided with two hydraulic propulsions. The ECO 200 Cutter Suction Dredger can pump the sand up to 1500m and dredge up to 6 meters depth. One of the advantages of the ECO dredger is the use for dredging in small and shallow areas that are difficult for bigger dredgers to enter. The draft of the ECO dredger is only 0.7m. This multipurpose cutter suction dredger is delivered completely assembled and launched into the water by mobile crane.

Dredge Yard to build ECO200 Auger dredger

Dredge Yard recently signed a contract to design, manufacture and deliver an ECO 200 Dredger with auger head. The auger dredger has a dredging depth of 6 m and comes with a 1500 m discharge pipeline. The ECO 200 Auger will be delivered to a mining corporation in West-Africa. There the ECO 200 Auger Dredger will be used for mining activities in a shallow river. The removed sand & gravel is then processed to capture gold and diamonds.

Special auger head

The economic auger head is designed to excavate with minimum spillage and provide the best suction performance. For this project, Dredge Yard is going to install small extended knifes on the auger. The objective of these knifes is to loosen the compacted river sands to be transported by the screw motion of the auger to the suction mouth. Sufficient pumping power is provided to transport the dredged material over a discharge length of more than 1500 m.

Shallow draft

The ECO 200 Auger Dredger will be built out of two main pontoons. This will provide sufficient floating capacity, but maintaining a shallow draft of around 0.8 m (2.65 ft). This allows the dredger to operate in shallow waters.

Customized dredging system for TSHD

Dredge Yard delivered a new customized dredging system for a trailing suction hopper dredger. The system consists of several components, such as dredge valves with inspection holes on both sides. The delivered dredge pumps are suitable for pumping and handling all slurry, mud, sand, gravel, rocks and debris. We also incorporated our turning glands with an adjustable turning range by using dismountable stoppers.

As you can see on our project page, we designed a new customized wear resistant steel loading box for the trailing suction hopper dredger. This way, the slurry can easily be pumped into the hopper for transport. Our hopper overflow drains the excess water, making it more efficient, because it leaves more room for the payload.

Of course this dredging system would not be complete without a drag head with jet water nozzles, suction arm and gantry. Dredge Yard also provided bow couplings, a sliding piece and bottom doors.
