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.
