EQUIPMENT
of two front-swing winches, the Bar-
racuda Class is a two-in-one dredge
that easily converts from a swing lad-
der dredge to a conventional dredge
without sacrifi cing portability. Avail-
able in either diesel or electric power,
discharge sizes range from 10 to 18
inches (250 mm to 450 mm).
Separately, and in another twist to
the ever-expanding DSC portfolio,
the North Carolina Department of
Transportation recently took deliv-
ery of a new, fully customized cutter
suction dredge, which it christened
the Dredge Manteo. The 154-foot
state-of-the-art pipeline dredge, de-
signed and built by DSC Dredge
will work to keep North Carolina’s
state-maintained intercoastal ferry
channels clear. Because the state of
North Carolina anticipated that its
ferry routes will see more and more
use, it was imperative that the DOT
had a more modern dredge capable of
dredging more material more quickly
than its predecessor.
The Manteo fi t the bill nicely. Built
to house two eight-person crews, with
a full galley, four bunk rooms and two
full bathrooms, the dredge also fea-
tures a 78-foot deckhouse that con-
tains the machinery area, crew quar-
ters and galley. Far more effi cient than
its predecessor, the 16” x 14” Manteo
is capable of dredging a channel to a
depth of 30 feet. Spud carriages, which
the original dredge did not have, easily
move the vessel as it works. From the
outset, DSC’s designers made several
recommendations to improve perfor-
mance that NCDOT agreed upon.
These included increased horsepower
of the engine and the diameter of the
impeller. This allows it to effectively
move more material over a 1.5-mile
distance to the discharge point. And,
the dredge includes a myriad of other
high-tech features, including a GPD
dredging system.
Standard Solutions for
Specifi c Situations
Customization is the key for the
DSC, but DSC’s diversifi ed standard
portfolio of dredging solutions can fi t
just about any need that you might
have. For example, the Marlin Class
underwater pump mining dredge is
designed to meet the needs of deep
mining and aggregate deposits by pro-
viding a more effi cient tool for mate-
rial excavation. Every Marlin Class
dredge is specifi cally designed to han-
dle a particular deposit—from sand
and gravel to industrial minerals—to
ensure maximum effi ciency. Beyond
this, DSC Marlin Class dredges are
available in either a diesel- or electric-
powered model to meet the custom-
er’s specifi c needs.
Still another DSC Dredge class, theShark, features modular design for
portability. Also offered in diesel or
electric power, the DSC Shark Class
cutter suction dredge features a con-
ventional dredge-operating confi gura-
tion with a modular design for ease
of transportation. The reliability of
the Shark Class cutter suction dredge
design typically results in a higher
percentage of operational time, and
it often exceeds the typical lifespan of
other dredges within the same class.
The DSC Badger Class is ideal for
smaller dredging jobs where more
compact equipment is required due to
work area limitations. With a work-
ing width of just under 10 feet and
an overall length of 54 feet, including
the ladder, the Badger can be maneu-
vered into harder-to-reach waterways,
yet still dig to a depth of 20 feet at
