DSC Dredge, LLC, a world leader in customized dredging solutions, continues to expand its international presence, with recent orders and deliveries into Nigeria, Republic of Congo and Alberta, Canada.
With energy costs soaring and spoil areas shrinking, transporting dredge slurry at the optimum flow rate and concentration is paramount.
Many factors contribute to limitations in the throughput of cutter suctions dredge. While most performance data available from cutter suction dredge manufactures outlines theoretical design throughput, others factors need to be considered when computing expected throughput.
Over the past 10+ years, many new products have entered the market that also apply to the dredge manufacturing processes. Original Equipment Manufacturers (OEM's) are spending more money and time into Research & Development to explore increased efficiencies, longer life and more affordable components. As these new components find themselves available for sale in the marketplace, they offer benefits to end users in many industries.
This paper will take us through the steps involved in the design and manufacture of the deepest mining dredge in the Western Hemisphere.
Japaul Oil and Maritime Services PLC (Japaul) is a rising star in the Nigerian dredging industry. Over the past several years, foreign dredging contractors have been replaced with Nigerian contractors, who have been busy updating their dredge fleets. Jegede A. Paul, Managing Director/CEO of Japaul, already owned dredges from Korea and Holland, and had previously taken delivery of his first DSC Shark (an 18-inch x 16-inch configuration) in 2007. Although the unit was used, DSC provides OEM parts information to all customers as an added benefit. Additionally, Mr.
DSC is proud to announce the launch of a new 22-inch x 20-inch Custom Electric Marlin class, self-propelled, hydraulic cutter-suction dredge at Arkhola Sand and Gravel’s operation in Fort Smith, Arkansas. The technologically advanced barge-loading dredge was designed so that it could be integrated into Arkhola’s existing processing plant, while drastically increasing their overall efficiency. The new dredge will maximize production and allow for a continuous operation with no operational downtime.
Many references to “dredging efficiency” exist in publications pertaining to the dredging industry but there exists, in my opinion, an absence of reference to the individual components of dredging efficiency, how each component is measured, and how each measurement is then calculated and expressed in useful terms.
PAL Technology is one of many companies owned and operated by the Royal Family in Abu Dhabi. In 2006, the company was faced with various projects, which included the development of artificial islands, deepening canals and land reclamation. Expected to be booked for projects through 2018, the company required extensive construction and navigational dredging capabilities in order to complete each job, so PAL was in need of a dredge with superior power that was also capable of performing in extremely high temperatures.
Lake Wildwood was built in the late 1960s as a lake recreation complex for people living in the Chicago and north-central Illinois areas. The lake covers more than 220 acres and is filled by water runoff from the upland agricultural area. Today, Lake Wildwood is home for many permanent residents who are retired or who live in the area and commute to larger city areas
