| description | A method and apparatus for making an electrical connection through a tubing hanger in a subsea well avoids the need for precise gauging and alignment. The tubing hanger has an electrical receptacle located on its rim and a guide hole also located on the rim. An impression block tool is lowered into the wellhead from the surface to make an impression of the rim to determine the orientation of the guide hole. A carrier is mounted to the tree connector at the surface. The carrier has a guide pin and an electrical connector. The carrier is aligned, then secured to the tree connector so that it can move only a limited amount rotationally. As the tree connector enters the wellhead, the guide pin will enter the guide hole, which is tapered. A limited amount of rotation of the carrier relative to the tree connector allows the electrical connectors to precisely align before contacting each other. |
