Abstract: An umbilical comprises an outer sheath defining an interior void; one or more power cores; and one or more forced convection cooling circuits disposed within the interior void proximate the power cores, typically at least one forced convection cooling circuit paired with each power core. The forced convection cooling circuit comprises a heat exchange delivery fluid conduit and a heat exchange return fluid conduit in fluid communication with the heat exchange delivery fluid conduit, where at least one of the fluid conduits is disposed either proximate to the other conduit or disposed within the other conduit. The forced convection cooling circuit has a length which has been determined to be sufficient to achieve a desired heat exchange that results in a desired efficient evacuation of heat energy from the power cores along a predetermined length of the umbilical.

Abstract: An umbilical cable assembly is created by a process which, in an embodiment, fits an abandonment cap onto an end of an electrically conductive cable as well as a polyethylene disc into which a set of connection pins have been pre-molded. The abandonment cap is injection molded onto the end of the electrically conductive cable where a cylindrical volume of polyethylene is concurrently injection molded to the polyethylene disc. In certain embodiments some of the connection pins are connected to the umbilical's conductive power core. The abandonment cap, fitted to an umbilical exposed end, includes an injection molded, substantially cylindrical volume of polyethylene disposed over the cable sheath; the disc in which a set of connection pins have been pre-molded; the concurrently injection molded, substantially cylindrical volume of polyethylene disposed over the disc; and a protective cover disposed at least partially over the disc proximate an exposed end of the umbilical's conductive power core.
