ABSTRACT OF THE DISCLOSURE Methods and apparatus for generating electric and hyd- raulic power adjacent an undersea oil well for use in operating the well-head equipment are provided herein. The apparatus in- cludes, in combination, a subsea oil well and means for generating electrical power in situ. The electrical power generates means includes a working fluid, and a heat exchanger which is arranged to pass crude oil from the undersea oil well through one side thereof and the working fluid through the other side thereof to transfer heat from the oil to the working fluid to heat the working fluid. A turbine is provided which is driven by the heated working fluid and a generator is driven by the turbine. A condenser is provided which is cooled by ambient sea water. Means are provided for passing the working fluid exhausted from the turbine through the condenser to the working turbine. A compressor is provided which is arranged to return the working fluid cooled by the condenser to the heat exchanger. The dif- ference in the temperature of the oil being extracted from the well and the temperature of the surrounding sea water is thus utilized to generate electric and hydraulic power in situ, adjacent the undersea oil well.
