Abstract : The Naval Civil Engineering Laboratory is developing diver-operated hydraulic tool system that uses seawater as the working fluid. The program was initiated in 1976 with the subsequent development of an experimental balanced vane by 1980. Late in 1980 a contract was awarded to improve the performance of the experimental vane motor and make it reversible; to couple the motor to a rotary impact mechanism with appropriate control to form a diver-operated impact wrench and to develop a diesel-operated portable power supply for operating the tool. This report describes the successful development of this experimental seawater hydraulic tool system. (Author)
