  • SYSTEMS AND METHODS FOR TRANSMITTING AND/OR UTILIZING HVDC POWER IN A SUBMARINE ENVIRONMENT
    Publication number: 20130175958
    Abstract: Systems and methods for transmitting and/or utilizing high voltage DC (HVDC) electric current in a submarine environment. The systems and methods may include the use of a submarine hydrocarbon pipeline to transmit both the HVDC electric current and a fluid stream. The systems and methods also may include the use of the HVDC electric current to do mechanical work within the submarine environment. Additionally or alternatively, the systems and methods may use a pressure-compensated electronics apparatus (PCEA) to receive the HVDC electric current and to produce a conditioned electric current therefrom.
