Abstract: A system for generating electrical energy comprises a circuit containing a working fluid, an evaporator configured for boiling the working fluid, a turbine driven by the vaporized working fluid, and an electric generator coupled to the turbine for creating electric energy. The system further comprises a condenser for condensing the working fluid which flows from the turbine, and a pump for pumping the working fluid through the circuit. A hydrocarbons pipeline transports hydrocarbons having a hydrocarbon temperature from a well, a seawater intake is configured for taking in seawater having a seawater temperature, and a seawater discharge is configured for discharging the seawater.
