February 26, 2013, Reserve, La. – The
Marlin Class underwater pump mining dredge manufactured by DSC Dredge LLC is
designed to meet the needs of deep mining and aggregate deposits by providing an
efficient tool for material excavation.

Every Marlin Class dredge is specifically designed to handle a particular
deposit, from sand and gravel to industrial minerals, to ensure maximum
efficiency. Deep digging capability is made possible by the use of an
underwater pump system with a high torque cutter drive assembly to complement
the rigorous demands of the deep mining industry. Digging depths range from 35
feet (10 m) to more than 200 feet (61 m), and discharge sizes range from 8
inches (203 mm) to more than 24 inches (610 mm) to allow for a wide range of
production and flow conditions to match specific mining operations.

DSC Marlin Class dredges are available in either a diesel- or
electric-powered model to meet the customer’s specific needs. Drive systems
include a Caterpillar ACERT diesel engine with inline direct marine style
transmission for dredge pump reduction, or TEFC electric motor, variable
frequency AC dredge pump motor drive and double helical gear reducer for dredge
pump reduction. All models feature a PLC operating system, magnetic flow meter,
electro-proportional hydraulic circuits, high-capacity service water system,
maximizer suction dilution valves and a 3-wire mooring system. These
performance features offer deep water dredging capabilities, combined with a
wide array of suction and discharge sizes, to maximize operating efficiencies
for every customer’s operation.

DSC builds each unit to the exact requirements of a particular operation
with quality in design. The company provides customers with intensive on-site
operations and maintenance training upon system delivery and long-term
aftermarket service and parts support throughout the world. Technical,
engineering and parts support is available for all types of dredges across the
world. DSC’s in-house automation department designs custom packages that can be
added to any dredge.
