Abstract: The present invention provides a fire-resistant electrical feedthrough system for use in offshore and top-side electrical submersible pump (“ESP”) installations. The fire-resistant electrical feedthrough system includes a minimum of two, redundant pressure barriers, in order to provide for safe operation and increased system reliability. The primary barrier is typically embedded within the wellhead equipment structure, while the secondary barrier is typically externally mounted.

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.

Abstract: An electrical penetrator assembly has a ceramic housing with a through bore, a first electrical conductor extending through at least part of the bore and terminating and having an outer end outside the bore and a second end, and a second electrical conductor having a first end in electrical communication with the second end of the first conductor and an outer end. The second end of the first conductor and the first end of the second conductor are in electrical communication and at least one of the conductors is movable relative to the other conductor to accommodate expansion and contraction as a result of temperature variations, and first and second seals extend between respective ends of the ceramic housing and the first and second conductor, respectively.
