Electric Cutter Dredger for Canada

Dredge Yard has received an order for a customized Cutter Suction Dredger from Western Potash Corp. (WPC)- a development stage potash company based in Canada. The customized dredger will be used in WPC’s Milestone Potash Project for dredging potash.

WPC confirmed that Dredge Yard was chosen to deliver this dredger, because it has “both the industrial experience in potash and right equipment offerings, and during the entire negotiation process were very quick with communications and responsive to client requests.” (Dr. Matthew Wood, Vice President Technology, WPC).

Customized dredger design

When designing a dredger for WPC, special attention was paid to achieve a solution that would be as ecologically and economically responsible as possible. Therefore, this ECO dredger features customization to optimize its efficiency for this project. An example of this is its four electric motors. Each motor drives a different component, allowing for optimal power use and high efficiency dredging that doesn’t waste any power. This is an approach, which is advantageous for both – budget and the environment.

In addition to optimal efficiency, the electric motor drives are used instead of a diesel engine. As a result, air pollution and the risk of fuel spillage during operation is eliminated. An electric driven dredger is also much quieter than a diesel model. This reduces noise pollution in the surrounding environment. Finally, the electric motors are cleaner and easily maintained compared to combustion engines. All these factors contribute to an ecologically and socially responsible dredging approach.

As this dredger is intended solely for dredging potash, it was completely redesigned for optimal performance for this project. According to operations manager at Dredge Yard, Michel Debo, “no two dredging projects are the same. Customized solutions help to achieve the best dredging performance under the specific project conditions.”.

Dr. Wood said that the customized dredger design was evaluated by WPC and SNC-Lavalin, concluding that:

“This model was the right balance of industrial quality, with an efficient CAPEX, low operating cost and good environmental credentials.”

The dredger is in the process of being built in Dredge Yard’s facility in Rotterdam, Netherlands. It will be tested and be delivered in early 2020.

About WPC Milestone Potash Project

The dredger will be used in WPC Milestone Potash Project Phase 1 Plant. More specifically, it will be placed in the Crystallization Pond (pictured below) and dredge potash from the pond. The dredged potash will then be sent for further processing, drying and compaction.

The environmentally conscious WPC Milestone Potash Project focuses on an innovative, horizontal mining method, which does not bring salt to the surface or produce a tailings pile. Additionally, this method reduces the amount of water in comparison to traditional solution mining, uses recycled water whenever possible, and strives to be as energy efficient as possible. Therefore, the ECO dredger is an ideal partner for this project.

Cutter Suction Dredger ECO 300 for Sri Lanka

Rotterdam, Netherlands – Dredge Yard and its sole agent in Sri Lanka, Hoavel Holdings, have won an order for a standard Cutter Suction Dredger ECO 300. CSD ECO 300 will be used by Sri Lanka Land Development Corporation (SLLDC) for a governmental project of cleaning the Beira Lake in Colombo, Sri Lanka. Representative of Hovael Holdings confirmed that Dredge Yard was chosen to deliver this dredger, because “SLLDC tender technical specifications were successfully complied with the ECO 300”.

Dredging project

Beira Lake is a man-made shallow body of water located in the city centre of Colombo, Sri Lanka. Due to its central location, the Beira Lake has become vital for a variety of residential, industrial, commercial, tourism and religious activities.

Problem/case

Due to its central location and use for a range of activities, the Beira Lake also suffers from pollution. For example, the lake is exposed to hard detergents and pollutants from hotels and hospitals either directly or indirectly connected to the lake. In addition to this, in certain areas, the sewer lines are illegally connected to the storm water lines, which causes waste water to enter the lake.

According to SLLDC, waste water and pollutants accumulate over time, which has resulted in poor water quality for the last three decades. Water pollution negatively affects both – the surrounding environment, and the lake ecosystem. Representatives at SLLDC added that this is “especially relevant during the dry season, where lower fresh water in flux and higher temperatures cause increased bioactivity in the lake, resulting in algal blooms, fish kills and bad odour around the lake”.

The main purpose of Beira Lake dredging is to improve the water quality by removing accumulated waste water and pollutants. This will restore a healthy environment in and around the lake. In addition to this, the lake will also be deepened to improve access and navigation for boats, to maintain the efficiency of commercial activities.

“We are proud to provide a tool for the maintenance of such an important water body in Sri Lanka. Cutter dredger ECO 300 will help to improve the water quality and environment, as well as contribute to Sri Lanka’s successful commercial and industrial activities” says Basel Yousef, Chief Executive Officer, Dredge Yard.

Cutter Suction Dredger ECO 300 specifications and delivery

Dredge Yard’s standard Cutter Suction dredger ECO 300 model was supplied with additional features according to the requirements of SLLDC. Yet, the standard, shallow draft CSD ECO 300 model is an ideal tool for Beira Lake dredging, which has an average water depth of 2 meters. Furthermore, its compact design will allow easy transportation to the centre of Colombo.

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.

Are you attending the event? Reach out and meet us for a chat about our efforts in eco-friendly dredging equipment development.

Dredge Ball Joints to the Middle East

Dredge Yard successfully delivered 50 heavy duty dredge ball joints to the Middle East for immediate use in the gulf region. These dredge ball joints are suitable for a thick pipe with internal diameter of 750mm at continuous pressure of at least 30 bar.

The ball joints are manufactured at Dredge Yard facilities in collaboration with our partners in the Republic of Turkey. The manufacturing process involves casting and heat treatment of all components, which is followed by machining to the finest tolerances. Some of our dredge ball joint benefits include:

  • Easy assembly and dis-assembly
  • Low maintenance required
  • Low friction between ball and gland due to grease grooves and polished ball and gland face
  • Replaceable liners made from wear resistant materials
  • Quick fix and release of locking
Dredge ball joint casing

Dredge ball joint components

Dredge ball joint testing & quality control

To ensure high quality and durability, all of our ball joints undergo heavy testing and quality control. Dredge Yard team of engineers always supervise the manufacturing and testing process. Therefore, we can guarantee that all parts are delivered in accordance with Dredge Yard specifications and to customer’s satisfaction. Accordingly, each dredge ball joint component is tested both – separately, and in combination with the other parts. This ensures its functionality and interchangeability in the dredging field.

Dredge ball joint testing

Dredge ball joint testing

During delivery, dredge ball joints are tested at pressures, which exceed the maximum operating pressure on site. More specifically, several dredge ball joints are statically tested over 30 bar for a duration of one hour.

Additionally, one of the dredge ball joints is tested at a special facility in a so-called dynamic test. During the dynamic test, the dredge ball joint is fully pressurized up to 30 bar, while a movement of the ball joint is created by a hydraulic cylinder. We do this to simulate the forces encountered when in use, and ensure durability of the component under severe conditions.

Finally, dredge ball joints are used by welding the heavy-duty steel pipe to two parts of the ball joint. Thick heavy welds are applied in order to ensure that the complete system withstands the pressure of at least 30 bar and external forces such as currents, waves and wind.

Post purchase support

Following the thorough manufacturing and testing process, we delivered all ball joints to a customer in the Middle East. Ball joints were ordered for immediate use at a dredging project in the gulf region. Dredge Yard service team will follow up with the customer for continuous monitoring and support on the use of dredgers, as well as assist whenever needed.

Dredge valves manufactured & delivered to GCC

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 to a client in Gulf Cooperation Council (GCC). 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.

Dredge Valve by Dredge Yard before paint

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.

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 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 CO2 emissions. 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.

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.
