THE CONTINUOUS DRAGLINE DREDGE--A CONCEPT

Until the present time the limit of dredges has been a depth of 150 feet, and wave action in offshore operations has been a problem. A new system of dredging has been designed to replace the conventional bucket-elevator and hydraulic types. The new dredge employs a number of dragline buckets connected by cables on each side, which gives a digging action similar to the dragline but with the added advantages of a conventional bucket line which swings across the digging surface. The dredge digs on a catenary, which provides a cushion for the buckets against wave action. A suspended lower idler device is used to shorten the length of hull which would be necessary for a pure catenary. Although the limits of the device are not known, it is expected to be able to dredge to a depth of 300 feet using 3-cubic yard buckets.
