  • Subsea variable speed drive apparatus
    Patent number: 11950389
    Abstract: A subsea variable speed drive apparatus comprising a pressure resistant container (90) comprising a curved wall section having a curved, internal surface (90a); and a variable speed drive comprising at least one power electronics module (50) arranged inside the container and held at a predetermined ambient pressure. The at least one power electronics module is mounted on a heatsink (40) which is mounted on the internal surface, the heatsink comprising a curved surface (40b) contacting the internal surface and having a radius of curvature corresponding to the radius of curvature of the internal surface. A subsea hydrocarbon fluid pumping system comprising such subsea variable speed drive apparatuses and a related method are also disclosed.

  • INSTALLATION FOR USING CONTROL FLUID AS BARRIER FLUID FOR ELECTRIC MOTORS COUPLED TO SUBSEA PUMPS
    Publication number: 20170009772
    Abstract: The present invention relates to the use of water-based control fluid in subsea systems as barrier fluid for electric motors (2) coupled to subsea pumps (1). For that purpose, a hose (HFL) (12) is arranged between an umbilical termination unit (9) and the electric motor (2) of the submersible pump (1), by means of a connection plate (MQC) (7). This installation makes more rational use of the space on the floating production unit by reducing the number of devices required for the implementation thereof, and by facilitating logistics regarding these products and devices.
