Dredge valves for capital dredging project

One of our most recent running projects involves manufacturing and delivery of dredge valves. More specifically, dredge valves of 850 mm internal diameter and working pressure of 20 bar.

The 60 valves and 15 hydraulic power units (HPUs) are ordered by a client in the Gulf Cooperation Council (GCC). The ordered components will be used on board the client’s new vessels, which are intended for capital dredging – creation of new artificial islands. In this project, our supplied valves will be used to divert discharge flow from one location to another.

Due to demanding work function and exposure to abrasive slurry materials, dredge gate valves are highly sophisticated components. Therefore, we select the most robust material and high pressure handling capability to ensure proper function and long component life.

The first batch of the order are to be delivered in the third quarter of 2019.

Dredge Yard is relocating to better accommodate its clients

Dredge Yard is expanding its business and will relocate to new headquarters and assembly hall to better accommodate its clients.

We are excited to announce that we are relocating to our new headquarters and assembly hall by August 1st, 2019. Our new office is located in Rotterdam South, Netherlands at the following address:

Brielselaan 69, 3081 AA Rotterdam, Netherlands

In the wake of new product development and team expansion in 2019, we are relocating closer to the industry of shipbuilding and dredging. Our new headquarters overlook the river Maas, and offer a glimpse of constant shipping traffic in and out of the largest port in Europe here in Rotterdam.

Business expansion in Rotterdam

This relocation marks a significant step in the company’s development. Aside from bringing Dredge Yard closer to its industry, the new headquarters will also house a big facility for product development and assembly.

Dredge Yard will now assemble, test and supply all equipment from its Rotterdam facility.

Therefore, we will now assemble, test and supply all equipment from our own Rotterdam facility. This will allow for even better control of assembly process, quality control and quick, reliable product testing right outside the office windows.

Closer to our clients

The modern headquarters are located in Rotterdam South, just 4 kilometres from the city centre. This location will offer our clients easy access to the facility. We will now provide the possibility to take a look at assembly process, newest developments, and equipment in stock.

Shorter lead times, due to assembly and testing taking place from its central office.

Furthermore, this change will allow us to offer shorter lead times, as assembly and testing of products will take place at our central location. Finally, equipment transport will be more convenient, quicker and cheaper for the EU clients.

Dredge Yard at Flood and Coast Exhibition & Conference in the UK

At Dredge Yard, we constantly seek new and innovative ideas. Therefore, we will be attending the upcoming Flood & Coast Conference at Telford International Center, UK from 18th-20th of June 2019. The conference focuses on “Risk, Resilience & Response in a Changing Climate”. The event gathers professionals from the Environment Agency, local authorities, water companies, research academics and more. We are looking forward to discuss climate change, flood resilience & working with the natural environment. This helps us in our mission to work towards even more eco-friendly and efficient dredging solutions that can to improve the environment and our standard of living.

Dredging as flood prevention

Due to constant environmental and societal developments such as climate change, population growth and pollution, dredging is becoming an increasingly important protective process. For example, between 1995 and 2015, flooding accounted for 47% of all weather disasters, affecting 2.3 billion people (UNISDR). Dredging can be an effective form of flood prevention, especially when it occurs due to gathered sediments and debris.

maintenance dredging diagram

Due to natural weathering and erosion, sand, silt and debris are constantly washed downstream. Sediments gradually fill up rivers, channels or canals making them very shallow and creating blockage. As a result, waterways become inaccessible to ships. Furthermore, blockage can cause water to flow over the river banks, flooding the surrounding area. Therefore, shallow waters can have major impacts on local businesses and even become a safety hazard to the surrounding residents and wildlife.

While dredging can be an effective tool in flood prevention, it is important to continuously develop existing dredging solutions for improved efficiency and the least environmental disturbance.

Innovative solutions to climate change

Flood & Coast conference this June will explore themes such as “How do we ensure our shared ambitions match the scale of the challenge and create climate resilient places for
people to live, work and play in? What is the latest evidence saying?” and “The practical action we can take now to create the skills, tools and technologies to revolutionise our preparedness
and awareness and to inspire action in the way we communicate risk, work with others and respond to incidents”.

Flood & Coast 2019 Conference

We look forward to discuss these themes and adapt the acquired insights to our future technology developments.

Dredging Safety Checklist

Dredge Yard continuously investigates and develops dredging equipment that is reliable, durable and eco-friendly. We strive to reduce environmental footprint and increase efficiency to achieve high quality equipment at the lowest cost for the client and the environment. Accordingly, we have previously introduced our adaptive auger head system, and in the first quarter of 2019, we launched our dredger series ECO 150.

However, dredging operations can also be risky for people involved. This is especially true for dredger operators, service and maintenance employees. The risks are raised by a variety of factors. For example, exposure to rough weather conditions and heavy machinery. Nevertheless, high safety standards, dedicated crew training and reliable equipment can ensure dredging safety for both – the environment and people involved.

What is safety in dredging?

When safety is discussed in the context of dredging, it can include multiple aspects. Namely, health and safety of people involved, dredger quality, and finally, protection of the environment. Fortunately, the importance of all safety aspects is receiving increasingly more attention in the dredging industry. Currently, most dredging equipment is developed with safety and sustainability in mind. We at Dredge Yard, also have a vision of a dredging industry, which offers a safe, healthy and accident-free work place. Therefore, we promote safety awareness and create possibilities for safer dredging work through our equipment.

Maintaining high safety standards and strict procedures on-board dredger vessels is vital. Whether it is during testing or dredging operation, safety procedures contribute to an accident-free workplace. There are safety measures that have become a standard across many industries. An example of this is Personal Protective Equipment (PPE). PPE describes equipment such as high visibility vests, safety glasses and other work wear. While it is a simple principle, PPE has become a crucial part of safety at work. Its introduction led to an extensive decrease in accidents on work sites. In addition to PPE, safety standards can be assessed through a variety of different codes and conventions such as International Organization for Standards (ISO), OHSAS or ISM.

Compliance with safety standards has become a high priority for all those involved in the dredging industry. IADC knowledge centre provides a thorough insight and explanations about the different standardization codes and conventions.

Safety standards

A large part of safety standards must be followed and implemented during dredging operation itself. Yet, there are factors starting at dredger design, engineering and manufacturing, which can contribute to dredging operation safety.

Dregde Yard's Auger Dredger Inspection

Dregde Yard’s Auger Dredger Inspection

At Dredge Yard “we want to involve our customers and suppliers in all our activities from the very early stage of the projects. We do this to ensure timely delivery, cost-effective production, low maintenance, low operation cost and high reliability of the products. Our customers are encouraged to witness any test in our production facilities.” (Basel Yousef, Dredge Yard CEO).

“Our customers are encouraged to witness any test in our production facilities” (Basel Yousef, Dredge Yard CEO)

Aside from the mentioned advantages, client involvement from the early stage allows our team to gain detailed insights to the client’s project. In this way, our team can identify and advice on project needs, that the client may not be aware of themselves at that stage. As an example, this can include specialized safety features, such as an adaptive auger head design rather than a standard auger solution.

Dredge Yard’s safety initiatives

In addition to close client relationships, we strive to contribute to safe dredger operations in a variety of ways, some of which are overviewed below.

  • We follow strict ISO and ASTM standards, as well as execute a variety of quality tests in multiple iterations.
  • We manufacture small, economic dredgers. Therefore, most of our dredgers are easily transported in a single, standard 40” container or on a flatbed truck. In this case, no assembly is required. Our larger dredgers are easily (dis)assembled in 3 parts through bolt connections. As a result, launching any one of our dredgers does not require any complex or potentially hazardous operations.
  • Our dredgers are easy to operate with joystick controls. Additionally, all information regarding dredging work is displayed on a control panel. This means that the dredging operation is simple. Additionally, the operator is not required to leave the cabin, as he has a good overview of dredging activity at all times.
  • In addition to easy operation, our dredger cabins are equipped with all necessities to ensure operator’s safety and comfort. As an example, it is mounted on vibration isolation pads and supplied with noise reduction, ventilation/heating, railings and more. Additional features can also be installed upon request.
  • Upon dredger purchase, we can provide on-site crew training on how to operate and maintain an ECO dredger. Training includes, but is not limited to: overseeing launch of the dredger; dredge operation and performance optimization training; dredger check-up & maintenance training. Since our dredgers are small and easy to operate, training is quick and efficient.

    Training in progress

  • Our service team is always available to identify minor or major technical issues over the phone, by e-mail, or come directly to your project site if needed.
  • Our dredgers can be supplied with any other additional safety features depending on your project conditions and requirements.
  • We also continuously work on developing new dredging solutions and components to incorporate in our standard dredger design for improved safety. For example, our cutter head teeth are designed with bolt connection for safe and quick maintenance through hammerless operation. Another example includes our dredge ball joints, which are designed with a gland (locking ring) for easy (dis)coupling of dredge pipes. By applying continuous improvements to our standard dredging equipment, we make sure that the dredger is efficient, safe and increasingly environmentally friendly.

Dredging for safety

While dredging involves certain risks, it is an important process, which can be used to ensure safety for the environment and people. For example, deepening of rivers and waterways is used as a form of flood control. Environmental dredging removes contaminated sediments in a controlled manner, to ensure safe water reserves and protection of  natural habitats.

Contaminated sediments in nature

Achieving complete safety in the dredging industry requires constant development and innovation of new solutions. In order to encourage this, IADC created the IADC Safety Award. This initiative is used to raise safety awareness, as well as to reward companies for their innovation or practices that illustrate special attention to, or overall contribute to safety in the dredging industry.

We are constantly in the development of new, safer dredging components and solutions to upgrade our standard dredger design.

Dredge valves manufactured & delivered

Dredge Yard specializes not only in small to medium sized dredgers, but also dredging and mining components. Accordingly, one of our most recent projects involved manufacturing and delivery of dredge valves. More specifically, dredge valves of 800 mm internal diameter. They will be used as a replacement of existing valves on board a trailing suction hopper dredger (TSHD). These types of dredge valves can be produced for three different working duties varying between 10, 20 and 30 bar according to the client’s requirements and application.

Dredge valves are used to control the flow of water and sand in the suction and discharge pipes of cutter suction dredgers or TSHDs. Due to demanding work function and exposure to abrasive slurry materials, dredge gate valves are highly sophisticated components. Therefore,  it is important to select robust material and high pressure handling capability to ensure proper function and long component life.

Design

All of our components, including dredge valves, are continuously developed and designed by our in-house team of engineers using the latest design software. In this way, we can guarantee high quality and durability of components.

Dredge Valve Manufacturing by Dredge Yard

Dredge Valve Manufacturing by Dredge Yard

We fabricate dredge valve body from high tensile steel, while the valve’s gate is made of corrosion resistant and hardened steel. These materials protect the valve against rust and wear. Additionally, high quality marine type paint is applied, for conservation of the outer surface, in order to protect the valve against corrosion.

Another special feature of our valves is the steel reinforced rubber seals. This makes the seal very durable, allowing it to handle large amounts of abrasive slurry, as well as to open and close smoothly, even in the toughest working conditions. Additionally, our dredge valves are designed in a way, where no fasteners inside the body can loosen and damage other parts during operation, even in tough conditions.

Aside from using robust materials, we always design easily maintained equipment for long-lasting life. For example, all connections outside the dredge valve body are bolts and nuts that can be easily replaced without damaging any part of the body. Furthermore, two inspection holes on both sides of the dredge valve allow for easy inspection inside the dredge valve body, without the need to dismantle it.

Inside Dredge Yard: history, ambition & innovation

Today Dredge Yard is among the leading manufacturers and suppliers of small to medium sized dredging equipment and components. But where and how did our journey begin and what does the future have in store? What are some of our biggest ambitions? Read on.

Where it all started

Our CEO Basel Yousef had been gathering experience within the dredging industry all around the world before settling in Rotterdam. Before Dredge Yard came to life, Basel had lived in Shanghai, which houses the biggest port in the world, Haarlem and Dubai, where the story of our company really begins.

Basel Yousef at Dredging Exhibition

Dredge Yard CEO Basel Yousef

In Dubai, Basel worked for a Dutch company, as a general manager of the middle east. Yet, this occupation could not fulfil constant need for new challenges and thirst for innovation. This led to a new chapter, and a real challenge – starting his own company in 2011. At this time, Dubai offered a lot of fast progress for the newfound dredging company. This was due to ongoing real estate and tourism related construction projects. Despite the newfound success, thirst for new challenges didn’t stop there.

Search for challenge in the Netherlands

This time, the centre of ports, dredging and shipbuilding – the Netherlands was calling. Basel says that he chose this country because of its relevancy to maritime, shipbuilding and dredging industries. Furthermore, he also sees Netherlands as a home to many highly educated people and universities within these fields. Additionally, many technological companies are based here, which offer great opportunities for development and innovation of the equipment that is at the core of Dredge Yard company.

 

Rotterdam – home to many international, tech companies and the biggest port in Europe is the perfect place for Dredge Yard

 

And that’s how in 2016, just 5 years after starting the company, Basel and Dredge Yard moved to the Netherlands. To begin with, the company was situated in Sliedrecht. But eventually, in 2018, Rotterdam, housing the biggest port of Europe and many international companies, turned out to be “the perfect place for us” (Basel Yousef, CEO).

While the headquarters settled in Rotterdam, our engineering office is still located in Dubai.

Dredge Yard Office Dubai

Dredge Yard’s Office in Dubai

Our great team of engineers in Dubai were part of Dredge Yard from the very beginning. They know our equipment to the smallest screw and are on-board with our strong company values. Because of this, and our dredging projects all around the world, Dredge Yard team can still be found on-the-go a lot, anywhere from Middle East and Asia, to Africa.

Company vision: environment, client & safety

Dredge Yard’s vision is to see a world where dredging operations are safe for both – people involved and the surrounding environment. Therefore, our focus is not only on manufacturing and supplying equipment, but also on the constant improvement and development of innovative digging instruments.

Environment

We strive for environmentally friendly solutions of highest efficiency. Our equipment should be used to improve the environment and standard of living. At the same time, it should not cause negative impact on living conditions under water and surrounding habitats. This is why we focus on our dredger series ECO. Among other advantages, ECO dredgers have lower fuel consumption, and thus, release less CO2.

This makes the ECO series a more environmentally friendly solution compared to large vessels that require large amounts of fuel.

 

We want to see a world where dredging operations are safe for both – people involved and the surrounding environment.

 

In addition to this, we promote durable, quality equipment and its regular maintenance, to ensure long dredger life and avoid frequent equipment disposal, which harms nature.

Client needs

Aside from environment, our focus is naturally, on client needs. Dredge Yard is known as an agile company, which is extremely flexible and fast. We try to respond to all inquiries on the same day to advice customers, who are often in a hurry to find the ideal equipment.

 

Dredging is an activity, which is unique to its environment (…) we believe that every project requires a different solution and we are here to adapt to it.

 

Furthermore, our standard engineering projects can always be adapted to the wishes of the customer. We strive to provide adapted dredger designs and drawings within a few days of the received inquiry (depending on the complexity of the project).

Dredge Ball Joint Functional Test: video

Dredge Yard specializes in manufacturing and supplying of dredgers and dredging components. Dredge ball joint is one of the component types we specialize in. Our manufacturing process takes place in the Republic of Turkey. It includes casting and heat treatment of all components, followed by machining to the finest tolerances.

We always conduct heavy duty functional tests, in order to ensure dredging equipment of the highest quality. One of such tests is called the dynamic dredge ball joint test. During the dynamic test, dredge ball joints are tested at a pressure, which is above the required design operating pressure. Additionally, while the ball joint is pressurized, a hydraulic cylinder applies a movement of the ball joint. This is done to simulate the working conditions in the dredge field at the most severe conditions. Severe conditions can include strong currents and waves, maximum dredge pipe length and highest pressure that the dredger can achieve. Therefore, the dynamic test is done to ensure component durability under all circumstances.

In February 2019, Dredge Yard delivered 50 dredge ball joints to the United Arab Emirates. These ball joints were suitable for a pipe with internal diameter of 750mm and discharge pressure of 30 bar. Therefore, during testing, we pressurized the ball joints to over 30 bar, in order to ensure that they can withstand maximum forces.

The video below provides an insight into our dredge ball joint dynamic test:

 

All About Dredging & the Environment

Dredging: environmental impact

Dredging is often associated with pollution, contaminated soils, CO2 emissions or other negative environmental impact. Yet, the positive perspective and nature improvements dredging can achieve are often overlooked. The word “dredge” itself is defined as the act of cleaning and clearing “the bed of (a harbour, river, or other area of water) by scooping out mud, weeds, and rubbish with a dredge” by Oxford Dictionary.

dredging and the environment

Accordingly, dredging is an activity, which to a large extent focuses on improvement of our society, businesses and even the environment itself. Furthermore, due to constant environmental and societal developments such as climate change, population growth and pollution, dredging is becoming an increasingly important protective process.

How can dredging improve the environment?

While there is a variety of dredging objectives, a large range of applications focus on improvement of the environment and nature protection. Some of these applications are discussed below.

Dredging rivers to prevent flooding

Due to natural weathering and erosion, sand, silt and debris are constantly washed downstream. Sediments gradually fill up rivers, channels or canals making them very shallow and creating blockage. As a result, waterways become inaccessible to ships. Furthermore, blockage can cause water to flow over the river banks, flooding the surrounding area. Therefore, shallow waters can have major impacts on local businesses and even become a safety hazard to the surrounding residents and wildlife.

River dredging is an example of an application with the objective of nature protection. It ensures not only waterway accessibility for ships, but also protection and safety of people and wildlife in the area.

Environmental dredging to clean contaminated soils

channel dredging landscape

Currently, one of the bigger issues that waterways face are polluted and contaminated soils, which become an environmental threat. Contaminated soils can negatively affect the environment and its inhabitants. In this case, environmental dredging is an effective method to remove polluted sediments. The soils must be cleaned in a controlled and precise manner, without spreading the pollutants in the surroundings. Accordingly, dredging solutions are continuously evolved to ensure precise dredging, which will not harm the environment or the operators involved.

Mine tailing removal for environmental safety

Dredge Yard mine tailing removal dredging landscape

Mining operations such as coal or gold mining can produce tailings, which are finely crushed rock and mineral byproducts of the operations. Tailings often contain leftover chemicals, which can be dangerous and must be regularly cleaned to not harm the environment. Storage and handling of tailings has become a major environmental issue worldwide, where dredging is an effective solution to protect the surrounding environment.

Dredging reservoirs for clean & safe water supply

Reservoir, lake & dam dredging landscape

Dams, reservoirs and lakes play an important role in our society. They provide power and drinking water, as well as act as an energy source and habitat for various plants and animals.  Just as in rivers, natural weathering, erosion and pollution threaten these water resources by clogging them up. Sediments can also contain chemical precipitates, which are especially harmful to the environment and life. This is another example, where dredging provides an effective solution to ensure clean, safe and sufficient water supply for the environment and life within it.

Environmental precautions when dredging

As discussed above, dredging is often an efficient solution to cleaning and improving the environment. Nevertheless, some aspects of these dredging projects must be considered in order to ensure minimal negative impacts on the nature.

Dredging equipment

all dredger engineered design

When it comes to dredging equipment – size matters, and bigger is not always better. In the dredging industry – dredger types & sizes vary from one-container-transportable ECO 150s to grandiose vessels, such as the Spartacus. It is immensely important to evaluate project conditions and choose the right equipment for your dredging project. An undersized dredger will not fulfil project requirements and can ultimately lead to additional costs. Choosing oversized equipment can unnecessarily break the budget. Furthermore, naturally, larger equipment requires more power and thus, has higher fuel consumption, which results in increased COemissions. Therefore, aside from increased expenses, choosing oversized equipment can also needlessly harm the environment.

Types of dredging methods

Choosing the right equipment goes hand in hand with the right dredging method. Some dredging methods can be considered more environmentally friendly than others. Thus, it is important to evaluate what is the most sufficient method for both – project requirements and environmental conditions.

Water Injection Dredging Diagram

Water Injection dredging is one example of the more environmentally friendly dredging solutions. One of the key aspects of this method is the fact that it involves nature itself in the dredging process by using water currents for material transportation. Additionally, water injection dredging does not involve material removal from the ecosystem. This contributes to sustainability of natural ecosystems that are vital in natural waterway processes.

There are also a variety of economic advantages of this dredging method, though it requires very specific environmental conditions to be sufficient. Find more about water injection dredging here.

Dredged material as a resource

cutter suction dredger 200 production

Whenever dredged material does not involve any pollutants, it should be considered as a valuable resource, which can easily be reused. Dredged, clean sediment can be used for a variety of different applications such as beach nourishment, land reclamation, soil improvement, construction materials and more. Multiple dredging projects with different objectives (e.g. maintenance and capital dredging) are often combined in order to achieve the highest benefit of the project. In this way, the environment is protected from immense impact of unnecessarily many dredging activities. Additionally, if not reused, dredged material is simply disposed of. This is an expensive solution, which can also harm the environment and habitats in the disposal areas.

ECO-friendly equipment

There is a variety of nature-friendly dredging objectives and precautions that can be taken to protect the environment. Nevertheless, it cannot be denied that dredging has certain negative impacts, as it is a form of interference with the ecosystem. Due to this, the dredging industry is increasingly focusing on new, innovative and green solutions, which would minimize any harm to the environment.

Adaptive auger head

adaptive auger head dredger

One of such ECO-friendly solutions is the adaptive auger head. Dredge Yard introduced the adaptive auger head system, which due to a strong suction vacuum, closely follows the ground when dredging. As a result, the adaptive auger head protects the marine animals from entering the suction system. It also causes minimal to no turbidity and accurately removes even the thinnest layers of sediment. Therefore, it is not only protective of the marine animals, but also of the general environment, especially when contaminated sediments are involved.

Additionally, our Auger dredger ECO 200 is equipped with the ECO-friendly system for environmental dredging. However, the adaptive auger head can also be purchased separately to upgrade existing dredgers. In this way, it can increase dredger efficiency, protect the environment and prolong your existing dredger life.

Water Injection ECO 150

Water Injection Dredger 150 3D model

Water Injection dredger ECO 150 is a compact dredger ideal for silt dredging and other small maintenance projects. It is eco-friendly due to its low CO2 emissions and water injection method, which does not involve material removal from the ecosystem.

Spare parts

All dredge ball joints

As an additional service, Dredge Yard offers dredge components from stock. We want to encourage maintenance, upgrading and modification of durable dredgers for a variety of applications. In this way, overproduction and rapid equipment disposal can be avoided.

Green(er) Future

Dredge Yard strives for a greener future, where dredging will not cause any negative impacts on the nature and its inhabitants. Therefore, we are constantly researching the newest technologies in order to design and engineer more efficient, greener dredging solutions.

Adaptive Auger Head: Environmentally Friendly Solution

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.

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.
