Development of an experimental seawater-driven hydraulic vane motor. The material requirements of the motor were investigated as were many design iterations. Through design changes and subsequent test and evaluation, an experimental motor was successfully developed. The motor, with a volume of about 410 cm 3 and a weight of only 2,3 kg, produced 2,46 kW (3,3 hp) at 1,600 rpm with better than 75 % efficiency. The working fluid of the motor can be either fresh 'tap' water or seawater. The fluid flow is 26,5 l/min at 6,895 kPa. The Civil Engineering Laboratory successfully tested the motor in the laboratory for more than 70 hours of operation at full power output. This paper describes the development program to data - the design, test, and evaluation. Plans for future improvements to the motor and the development of a complete seawater hydraulic tool system are also described. (Wassmann)
