Abstract
A seawater power source for providing pressurized seawater to hydraulic ts which utilize the pressurized seawater as their operating fluid. Included in the present invention is a diesel engine for driving a source of compressed air which, in turn, drives a first pump for withdrawing seawater from the ocean and transferring the seawater to a reservoir, and a second pump driven by the diesel engine for withdrawing seawater from the reservoir, pressurizing the seawater and supplying the pressurized seawater to the hydraulic tools. The present invention also includes a unique hose reel which facilitates the changing of tools by allowing an operator to change pressure and fluid flow rate while the seawater power source is operational.
