Seabright that had served the harbor for 30 years labored
to keep up, and frequent breakdowns only compounded
the problem. Fortunately for the harbor members and
visitors, a new dredge from DSC Dredge, LLC – the Twin
Lakes – was scheduled for delivery in June.
The Seabright was at the end of its useful life. Enter
the Twin Lakes, commissioned from DSC in April 2015,
a custom-built, 16” x 16” dredge with a hull-mounted
pump. It features a PLC operating system with color touch-
screen controls, Global Positioning System (GPS), electro-
proportional hydraulic circuits, high-capacity service water
system and an inline direct marine-style transmission for
dredge pump gear ratio reduction. A planetary winch pro-
vides the swing operation. A magnetic fl ow meter shows
the operator the velocity of the material being moved, pro-
viding information on the dredge’s effi ciency. With two
engines – a Caterpillar C32 dredge pump marine diesel en-
gine and a Caterpillar C18 marine diesel-powered electric
generator – the dredge complies with EPA and California
CARB environmental standards.
Meanwhile, the Seabright is now for sale. That’s an im-
pressive run for the DSC dredge; one which is probably
not yet over.
Custom Deliveries a Specialty
DSC has always produced ‘spec’ units out of its Green-
bush, MI, facility. Wetta adds, “We have also recently
added some ‘spec’ builds in our business model out of our
other two facilities. The spec build dredges range from 8”
through 18” discharge sizes.” That said; the real strength of
DSC has always resided in the ability to give the customer
what they want, where they want it and delivering that
product on time. For example, the DSC Barracuda Class is
really two dredges in one.
The Barracuda dredge features a swinging-ladder design
and is easily transportable, making it ideal for navigation-
al, recreational or restorative projects, such as waterway
maintenance and lake revitalization. Offering the option
