Abstract

The present invention provides a modular electrical feedthrough system for use in offshore and top-side electrical submersible pump (“ESP”) installations. A modular electrical connection system includes a stab receptacle assembly for mating with a stab plug assembly and a compliance mount. The stab plug assembly includes stab plugs and guide funnels adapted to guide the stab receptacles into a mating position with the stab plugs. The compliance mount compensates for physical misalignment between stab receptacles and stab plugs. A tubing hanger assembly forms a pressure barrier at a production bore by use of a tubing hanger penetrator assembly including a set of seals to isolate the electrical penetrator from the production bore. A secondary penetrator assembly provides a redundant pressure barrier for increased safety and system reliability.

Claims19

Dependent claims

A modular electrical connection system for pressure containment applications, the electrical connection system comprising:

a stab receptacle assembly, the stab receptacle assembly comprising:
a stab receptacle base;
a compliance mount adapted to provide misalignment tolerance in at least one direction and disposed on the stab receptacle base;
a set of stab receptacles, each stab receptacle in the set of stab receptacles being connected to a cable pigtail and being adapted to mate with a stab plug in a set of stab plugs;
and
a stab plug assembly disposed oppositely facing the set of stab receptacles, the stab plug assembly comprising the set of stab plugs and a set of conical guide funnels, the set of conical guide funnels adapted to guide the set of stab receptacles into a mating position with the set of stab plugs in part by a flared upper portion for each conical guide funnel in the set of conical guide funnels that protrudes beyond and is relatively larger than a substantially cylindrical lower portion;
wherein the set of stab receptacles are disposed on the compliance mount and facing the set of stab plugs for matingly connecting with the set of stab plugs, and wherein the compliance mount is adapted to compensate for a range of physical misalignment between the set of stab receptacles relative to the set of stab plugs to facilitate successful mating connection.

4 more elements

A modular electrical connection system for wellhead applications, the electrical connection system comprising:

a tubing hanger assembly comprising:
a tubing hanger disposed within a completion tubing hanger and adapted to form a pressure barrier at a production bore, the tubing hanger having an upper portion disposed above the production bore and a lower portion disposed within the production bore;
a stab plug assembly disposed on the upper portion of the tubing hanger;
a tubing hanger penetrator assembly comprising:
an electrical penetrator;
a tubing hanger penetrator sealing module disposed around the electrical penetrator and within the tubing hanger;
a termination housing adapted to withstand temperatures and pressures in the production bore and disposed in the production bore and at the bottom of the tubing hanger, the termination housing having a top and a bottom and comprising:
a protective clamshell housing forming a termination volume about a sealing boot and a cable and adapted to withstand temperatures and pressures in the production bore;
a termination housing end disposed at the bottom of the termination housing, the termination housing end comprising a set of seals;
wherein the termination housing and the protective clamshell housing are matingly configured so that the protective clamshell housing may be received within the lower portion of the tubing hanger in a secure manner;
and
wherein the protective clamshell housing of the termination housing in combination with the set of seals isolates the electrical penetrator from the production bore.
