Improvement and important changes on dredges have increased production, making possible continued operation despite rising costs; dredging operations are being introduced into new areas; optimum production is obtained by varying dredge bucket size and line speed; dredges have high-speed bucket-lines running up to 35 buckets/min; operations are generally continuous.
