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. 

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.

Dredge Yard presents latest developments at WEDA Mexico 2015

Dredge Yard was the Gold sponsor of the WEDA Mexico 2015 Annual Meeting. That meeting took place in the Centro Asturiano de Polanco located in the heart of Mexico City’s bustling Polanco neighborhood. There Dredge Yard presented their latest developments at the WEDA in Mexico.

At the event, our Marketing Manager, Iulia Berchiu and the CEO, Basel Yousef presented our dredging equipment and dredging solutions. In addition, they provided information about Dredge Yards latest projects that are dedicated to achieving the highest performance while protecting the environment and cutting the costs. Some of these projects are:

  • Dis-mountable cutter suction dredger 450 that is under construction in the Netherlands;
  • The ECO 200 Auger Dredger is designed to be compact, economic and therefore easy to transport;
  • The auger dredger is similar to ECO 200 Cutter Suction Dredger, but equipped with an auger head for sediment and sludge dredging. Presumably the auger dredger will be delivered at end of this year.

Dredging opportunities at WEDA Mexico

The WEDA Mexico Annual Meeting 2015 focused on the many dredging opportunities available in Mexico. These opportunities are a result of Mexico’s robust port infrastructure development and investment program. The meeting 2015 brought together professionals around the world to provide expert advice and share ideas. These professionals included Mexico’s Ministry of Transportation, Mexican port authority officials, the U.S. Army Corps of Engineers, the Panama Canal Authority.

According to Frederick Paup, Chairman of the Board Manson Construction Co., the event was informative. The company also appreciates the excellent turnout by the Mexican port authorities’ representatives.

Panama topic was brought up by the International Trade Specialist of the Panama Canal Authority, Javier Gilberto Carrillo Koo. He explained the impact and opportunities involved in the Panama Canal expansion.

Arturo Cors de la Fuente, Business & Institutional Relations Director of the CICE Group (Integral Foreign Trade Corporation) discussed the evolution of Mexican Ports. That evolution is considered a growth approach.

Open to private companies

Arturo Cors de la Fuente states: “Dredging in Mexico has changed during the last years. Before it was a Government activity and only large projects were subject of hiring private companies. Nowadays, the market has opened up to private companies and there are few exceptions. Only the Mexican Navy that holds the dredgers for their own purpose. In the last decade Mexican market has contracted an average of $90 million/year reaching a peak of about $260 million in 7 years. ”

Both foreign and local companies are getting many opportunities at the Mexican dredging market. Juan Ignacio Cruz Lomeli, the GM of Desazolves y Dragados, related that the dredging industry is an activity that demands specialization and therefore can’t be handled by companies without experience.
“The conference filled my expectations in terms of exchanging ideas and networking. And as Ricardo Hernandez, the President WEDA Mexico Chapter, said: I hope this is the first congress of many more because we need to establish a close group of dredging experience here at the WEDA in Mexico.”

Dredge Yard is showcasing at WEDA Mexico Chapter

The WEDA Mexico Chapter, representing all regions in Mexico, will at its 2015 Annual Meeting bring together dredging contractors and manufacturers from across the globe, senior U.S. and Mexican government and port officials, experts in the infrastructure, energy and dredging sector.

Dredge Yard, the dredging and mining manufacturer, is participating in the Mexican Chapter held in Mexico City, as a Gold Sponsor of the event.

The event will be a great opportunity for Dredge Yard to exchange ideas and experiences, share projects related information and find solutions for the Mexican dredging and port infrastructure development programs.

Meet our support team at WEDA Mexico Chapter

Dredge Yard’s support team will be present at the event to give all the information needed about the latest dismountable CSD450 Dredger that is under construction.

The company will also present the ECO 250 Cutter Dredger that has been designed after the advice of several dredging companies that have a need for a compact, economic and easy to transport dredger; as well as the ECO 200 Auger Dredger which is similar to ECO 250 but equipped with an auger head for sediment and sludge dredging.
