ABSTRACT:
A submersible pump installation for a subsea well has an electrical connection that is hydraulically made up with provisions to avoid contact with sea water. The submersible pump is suspended by a suspension head located in a tubular member at the subsea wellhead. An electrical insulator is movably carried in a passage extending through a wall of the tubular member. An electrical connector pin is carried in the insulator. A piston moves the insulator into contact with the suspension head, then the connector pin into engagement with the electrical connector located in the suspension head. A seal and dielectric fluid in the suspension head serve to prevent contamination by liquids in the subsea wellhead.
