THE COMPENSATED CUTTER HEAD DREDGE--A SOLUTION TO BEACH RESTORATION
America's beaches are eroding significantly and in some localities are severely damaged or destroyed. The Army Corps of Engineers' Report on the National Shoreline Study states that 2700 miles of shoreline is in critical condition and 1.8 billion dollars should be spent to protect this great natural resource. While various methods of shore protection may be used, "artificial fill with periodic nourishment to restore and preserve a beach is the preferred method." To this date, the only viable hydraulic dredge to operate offshore is the hopper dredge, expensive to operate and procure. The more economic and efficient cutter head dredge can be adapted to the offshore conditions by providing compensation equipment to offset the motion of the sea. Design requirements of such an offshore cutter head dredge design are presented as well as first costs and operating cost information. More formidable than the technical equipment problems are the contractual problems involving the federal, state, county and municipal bureaucracies. This problem is analyzed and a recommendation is presented for the ultimate solution to the restoration and preservation of our great natural resource--the Nation's shoreline.
