Abstract
A system and method of using accumulator(s) to generate electrical power in a marine environment. The system includes a first power source coupled to an electric machine coupled to a hydraulic pump coupled to an accumulator. The first power source is a power supply operable to convert AC to DC, and the accumulator is a high-capacity hydraulic energy storage device. The electric machine configured to operate as an electric motor driving the hydraulic pump in a first direction charges the accumulator. The charged accumulator configured to drive the hydraulic pump in a second direction driving the electric machine configured to operate as an electric generator to generate a second power source. The hydraulic/electric power system also includes a first controller configured to operate a first electrical load powered by the first power source and a second controller configured to operate a second electrical load powered by the second power source.
