Molded testable long term subsea abandonment cap for electrical cables and method of manufacture

摘要

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.

1. An umbilical cable assembly, comprising:
a. an electrically conductive cable, comprising:
i. a cable sheath; andii. a conductive power core disposed within the cable sheath, the conductive power core comprising an exposed end; and b. an abandonment cap fitted to the exposed end, the abandonment cap comprising:
i. an injection molded, substantially cylindrical volume of polyethylene disposed over the cable sheath;ii. a disc in which a set of connection pins have been pre-molded, a predetermined subset of the set of connection pins being operatively in electrical communication with the conductive power core;iii. a concurrently injection molded, substantially cylindrical volume of polyethylene disposed over the disc; andiv. a protective cover disposed at least partially over the disc proximate the exposed end of the conductive power core.
