Electrical Feedthrough For Subsea Submersible Well Pump in Canister
First Claim
1. A subsea pump assembly, comprising:
- a tubular conduit adapted to be installed subsea, the conduit having a longitudinal axis, an upstream end plate, and an inlet for flowing well fluid into an interior of the conduit;
a power cable opening extending through the upstream end plate;
an electrical submersible pump (ESP) in the interior of the conduit, the ESP comprising a motor assembly and a pump, the pump having an intake in fluid communication with the well fluid in the interior of the conduit, the pump having a discharge for pumping the well fluid from the conduit;
the motor assembly having a motor assembly housing with an upstream end that secures to an interior side of the upstream end plate over the power cable opening; and
a power conductor extending through the power cable opening into the upstream end of the motor assembly housing.

Abstract
A subsea pump assembly includes a tubular conduit that has an upstream end plate and an inlet for flowing well fluid into an interior of the conduit. A power cable opening extends through the upstream end plate. An electrical submersible pump and motor are in the interior of the conduit. The motor has a motor assembly housing with an upstream end having an electrical insulator opening. An end connection secures the upstream end to an interior side of the upstream end plate with the insulator opening registering with the power cable opening. An insulated electrical connector is mounted in the insulator opening. A motor wire in the motor assembly housing joins to an inner end of the electrical connector. A power conductor extends from exterior of the conduit through the power cable opening and joins to an outer end of the electrical connector.
