North Carolina anticipated that its Still another DSC Dredge class, the yet still dig to a depth of 20 feet at 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 ? 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 ef? 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. 39 www.marinelink.com MN
