Two Ellicott Dredges Work to Restore National Wildlife Refuge

DELAWARE, USA – Two Ellicott 460SL dredges are currently being used in a large tidal marsh restoration project at Prime Hook National Wildlife Refuge in Delaware. This is one of the largest marsh restoration projects ever in the eastern U.S. The project will restore a highly damaged tidal marsh/barrier beach ecosystem covering about 4,000 acres (1618.7 ha) within the former freshwater impoundment system on the refuge. This coastal wetland restoration improves the ability of the refuge marshes to withstand future storms and sea level rise and improves habitat for migratory birds and other wildlife.

AMEC and their marine subcontractor, Dredge America, have had great success since the restoration work began in June. Each dredge operates 10 hours per day, six days a week. “We are happy with the dredges and appreciate Ellicott’s support not only with this project but with all of Dredge America’s projects across the U.S.”, says Sam Robinson, Project Engineer for Dredge America.

They have already dredged more than 1.5 miles (2.4 km) of tidal channels and plan to dredge 30 total miles (48.3 km) of channel by next summer.

The first phase of the project will focus primarily on draining the marsh and improving tidal circulation. They will begin pumping sand onto the shoreline to close the breaches and create a back-barrier marsh platform. Overgrowth of phragmites, an invasive species of perennial grass, has resulted in the reduction of the wetland area. Establishing a constant salt water flow will help eliminate the phragmites. This restoration of habitat and natural tidal water circulation will enable salt marsh vegetation to return and flourish, improving the resilience of refuge wetlands against future storms and sea level rise, and providing valuable habitat for birds and other wildlife.

Tappan Lake Dredging Begins with Ellicott 370 Dragon Dredge

lake-dredgerHARRISON COUNTY, OH (USA) – The dredging of parts of Tappan Lake have finally begun with the equipment actually in place and on the water, according to Barbara Bennett, director of administrative services for the Muskingum Watershed Conservancy District (MWCD).

The matter was discussed at last Friday’s monthly meeting, which was held at Mansfield’s Charles Mill Lake Park.

Bennett stated that 400,000 cubic yards of sediment would be removed from the bottom of Tappan, which would take place near Beaverdam Run Bay, Clear Fork Bay and along both sides of Deersville Road.

The silt is to be vacuumed through flexible pipeline, which will cross under U.S. 250 to a site MWCD owns, which is at the northwest corner of Addy Road and U.S. 250, according to Bennett.

The big blue and white machine with a large orange fixture was given the name “CADIZ,” she said and added that the dewatering racks and basins were set up at the Addy property.

“The dewatering system is by mechanical means and state of the art systems,” Bennett stated by email. She said that using the pumping system would cut down on truck traffic, which would normally be used in hauling away the sediment. The dewatering system, which had been discussed in a previous MWCD meetings, is a system, which dries out the sediment much quicker, allowing recipients of the material to use it sooner than normal.

“We’re having ongoing discussions with Harrison County and also…ODNR (Ohio Department of Natural Resources),” Bennett said. “Nothing [has] been finalized but we will have over 400,000 cubic yards of material so there’s good material available for fill or use somewhere.”

Harrison County Commissioner, Don Bethel, stated the same that they were still discussing the matter with the MWCD and that they were still very interested in obtaining some of that sediment being pulled up from the lake.

Bethel had stated in a previous meeting earlier in the year that one idea for acquiring the sediment would be for use in filling the many small valleys near Industrial Park Road. The idea is to flatten out more land in order for the area to be even more attractive to prospective businesses, which have begun springing up there already.

Ellicott Announces Completely New Series 2070 Dragon® Dredger

BALTIMORE, MD  Ellicott is pleased to announce a completely new design 20” (500 mm) cutter suction dredge, the Series 2070 Dragon® dredge.

The new dredger takes advantage of modern, up-to-date technology and advanced design techniques. This unit will eventually replace the renowned Series 1870 Dragon as Ellicott’s standard and in-stock 20” dredge.


“This is a truly modern and efficient design without any sacrifice of the versatility, long life, and high production rates that owners of the 1870 have come to expect,” says Paul Quinn, Vice President of Sales for Ellicott. “With over 18 months in development, this is the most thoroughly researched and developed design that Ellicott has ever had.”

Like the 1870, the 2070 Dragon supplies ample power to the pump using a dedicated engine rated at 1300 HP (970 kW) and has a separate 440 HP (328 kW) engine dedicated to the hydraulic system. This dual-engine system allows for full hydraulic power to the cutter and winches, even when reduced RPMs on the pump are called for – something single-engine dredges cannot do.

All engines are from Caterpillar and meet all current air quality standards.


The entirely new hull was designed to meet BV Rules for Sheltered Waters. The new design criteria allows for increased portability and easier construction in the field. Ellicott accomplished these goals by reducing the number of side pontoons from four to two. In addition, the dredge uses a new, simplified bow gantry design.

Another major improvement is the hydraulic system, which is now based on highly efficient variable displacement pumps. This approach allows for lower HP input and thus less fuel usage to get the same hydraulic power to the devices. The 2070 is also equipped with a modern electric over hydraulic control system using Parker IQAN controllers for increased reliability.

Dredger 2070 Controls

Options such as anchor booms, or spud carriage, or swivel elbow discharge can be easily added.

With its design to BV Sheltered Water rules, 20” (500 mm) discharge, 50’ (15 m) digging depth, and improved portability, the Series 2070 Dragon is suitable for a variety of projects. These applications would include: harbor, river and waterway dredging, land reclamation projects, sand mining, and mining and tailing pond assignments.

Summary Specifications – 2070 Dragon Dredger

Total Installed HP/KW: 1740 HP (1297 kW)

Main Engine: CAT C32 Diesel Engine, 1300 HP (969 kW)

Ellicott anuncia Nueva Draga Serie 2070 Dragón®

BALTIMORE, MD — Ellicott se complace en anunciar un nuevo diseño de draga de corte succión de 20″ (500 mm), la Serie 2070 Dragón®.

La nueva draga incorpora la más moderna tecnología y las técnicas más avanzadas de diseño. Esta unidad eventualmente reemplazará a la famosa Serie 1870 de Ellicott de 20″.


“Este es un diseño muy moderno y eficiente, que mantiene la versatilidad, larga vida, y las altas tasas de producción que los propietarios de la 1870 ya conocen”, dijo Paul Quinn, vice-presidente de ventas de Ellicott. “Con más de 18 meses de preparación, este es el diseño más minuciosamente investigado y desarrollado que Ellicott ha hecho.”

Al igual que la 1870, la 2070 suministra gran potencia a la bomba, usando un motor principal dedicado con potencia nominal de 1,300 HP (970 kW).  Además del motor principal, la 2070 cuenta con un motor auxiliar de 440 HP (328 kW) dedicado al sistema hidráulico. Este sistema de doble motor brinda independencia al sistema hidráulico con respecto al sistema de bombeo.  Esto es algo que las dragas con un solo motor no pueden hacer.

Todos los motores son de Caterpillar y cumplen con todos los estándares actuales de emisiones.


El nuevo casco fue diseñado para cumplir con las Reglas BV para zonas de aguas protegidas.  Este nuevo diseño brinda además una mayor portabilidad y facilita en gran medida el ensamble de la draga en campo. Ellicott logra estos objetivos mediante la reducción del número de pontones laterales, de cuatro a dos. Además, la draga incorpora un nuevo diseño de pórtico de escalera.

Otra mejora importante es el sistema hidráulico, que ahora se basa en bombas de desplazamiento variable altamente eficientes. Este enfoque reduce el uso de combustible para obtener la misma potencia hidráulica en los dispositivos. La 2070 también está equipada con un moderno sistema de control hidráulico eléctrico, con controladores Parker IQAN para una mayor confiabilidad.

Dredger 2070 Controls

La draga 2070 puede además incluir opciones como “anchor booms”, “spud carriage” y codo giratorio.

Con su diseño BV para aguas protegidas, bomba de 20 “(500 mm), profundidad de dragado máxima de 15 m, y una mayor portabilidad, la draga 2070 es ideal para una variedad de aplicaciones.  Estas aplicaciones incluyen: dragado de puertos, ríos, dragado de navegación, proyectos de recuperación de tierras, extracción de arena, minería, etc.

Draga Ellicott 1270 de 18” en Rio Salado, Argentina

draga-argentinaUna draga Ellicott modelo 1270 con bomba de diámetro de 18” y potencia total de 1350 HP viene realizando trabajos de dragado para control de inundaciones en el rio Salado, cerca de la ciudad de General Belgrano, en Argentina. El proyecto incluye la remoción de aproximadamente 15 millones de metros cúbicos de arena y sedimento del rio. El objetivo con este proyecto es el aumento de la capacidad de conducción del rio. Además, el material extraído se utiliza para recuperar tierras bajas cercanas, incrementando su elevación, para así evitar las inundaciones recurrentes. Gracias a esto además, se incrementa al área de tierra productiva en la región. La zona a dragar cubre unos 37 km de longitud del rio. Las empresas José J. Chediack y Helport son las responsables de este proyecto.

argentina-draga-1270Uno de los aspectos claves de este proyecto fue el tema logístico. Las riberas en la zona a trabajar cuentan con muy limitado acceso, lo cual fue un punto a considerar como parte de la movilización de la draga de 30m de largo y casi 100 toneladas. Afortunadamente esta draga, a pesar de su tamaño, es relativamente fácil de movilizar, montar y desmontar sin necesidad de mayor infraestructura. Los técnicos de Chediack y Helport impresionaron al personal de Ellicott por la eficiencia, profesionalismo y rapidez durante la movilización, armado y puesta en marcha de esta draga, lo cual se realizó en muy pocos días y sin mayores problemas.

ellicott-draga-argentinaOtras dificultades que se han dado durante este proyecto son las recurrentes inundaciones, las cuales paralizan las operaciones por varios meses debido a que hacen imposible acceder a los lugares de trabajo e inundan los lugares de depósito de material. Además de esto, existe un total de cuatro puentes a través de los cuales las dragas solo pueden ser trasladadas cuando el rio está bajo.

SAMIT, empresa representante de Ellicott en Argentina brindo apoyo clave durante el ensamblaje y puesta en marcha de la draga y al día de hoy continua brindando su apoyo para cualquier tema post-venta.


Marina Dredging at Fire Island was successfully completed with an Ellicott dredge

Watch Hill Marina Dredging Completed

Fire Island National Seashore’s Watch Hill marina is now open following successful completion of the maintenance dredging program.

Watch-Hill-Marina-Dredging-CompletedThe dredging completed in the Watch Hill channel will provide safe passage for ferries, emergency services, and private boaters for many summers to come” said Fire Island National Seashore Facility Manager James Dunphy.

Portions of the navigation channel to Watch Hill – accessible by passenger ferry, private boat, and foot only – were dredged this past winter to maintain safe, public access to marina and docking facilities.

More than 29,000 cubic yards of material were removed from the channel despite winter weather delays. The dredge project, funded by Hurricane Sandy appropriations, began in December 2014 and was stalled until mid-March due to severe winter weather and extensive ice in the Great South Bay.

The New York State Department of Environmental Conservation granted a permit extension to H&L Contracting in January 2015 to extend the operation past the initial January 15, 2015 deadline and work was completed on March 31, 2015.

Ellicott 460SL Swinging Ladder dredge to be used for marsh restoration at Prime Hook National Wildlife Refuge

Prime Hook Refuge work to start in June

Work to restore the marshes at Prime Hook National Wildlife Refuge is expected to start June 15, the first phase in a $38 million plan to build storm and sea level rise resiliency on the 10,144-acre federal holding along Delaware Bay.

Step one will be to carve out relic drainage channels that historically allowed the marsh to drain. Once drainage is restored, 1.1 million cubic yards of sand will be pumped onto the beach just south of Fowler Beach road to fill openings that formed or were worsened during Superstorm Sandy.

A created dune will be planted with grasses to help stabilize it and allow the adjacent wetland to recover from decades of human manipulation, including 25 years where water levels were lowered and raised to accommodate wildfowl.

The marsh, despite its proximity to Delaware Bay, was maintained as a freshwater wetland. When storms broke through the dunes, it rapidly converted to a salt marsh and freshwater plants died. The marsh will be planted with salt-tolerant species.

The project is expected to last 30 years even if sea level rises 1.6 feet by mid-century as some projections suggest,” said Al Rizzo, project leader for the Coastal Delaware National Wildlife Refuge Complex Bombay Hook National Wildlife Refuge and Prime Hook National.

Cheboygan River Dredging Resumes with Ellicott 670 Dredge

The Cheboygan River dredging program is back on track after crews had to stop works on the project due to unsafe weather conditions in December, reported Cheboygan Daily Tribune.

670-dredge-cheboygan-riverAccording to City Manager Tom Eustice, the contractor, Luedtke Engineering Company, has begun dredging again to complete the task.

It’s good to see them back here,” Eustice said. “It’s just another sign of spring.”

The dredged material is slated to be dumped in Lake Huron at an 80-foot-deep disposal area that is about two miles straight out from the river.

Dredging will also take place further down the river, including as far south as Plaunt Transportation, which operates ferry service to and from Bois Blanc Island
