Book Description
A unique system for mining ocean bottom bottom sand from a small vessel was conceived and developed under the University of Hawaii's Sea Grant Program. Called the Submarine Sand Recovery System, or SSRS, it consists primarily of a suction probe which buries itself in thick deposits of sand by hydro-jet action and removes large cones of sand which can be transferred to shore for beach replenishment. The probe is handled on the bottom by divers with the aid of a special underwater lifting drum. The head is fitted with a hydraulically powered roller-crusher to grind up coral, rock, and shell fragments at the sand inlet. It is expected tht under certain conditions the system will provide a more economical and ecologically sound means of recovering offshore sand than is offered by conventional dredging systems. Laboratory and ocean tests were conducted on a series of models. A prototype (6-inch diameter pipe) was constructed and underwent preliminary testing in November of 1972.
