Abstract
A subsea running tool receives electric potential from a control unit located at a platform through a tubular string having an electrically conductive wire formed in tubular wall of the tubular string. The running tool provides at least one electrically operated function for setting a subsea wellhead component. The running tool is then run on the tubular string from a surface platform to a location within a wellhead. Electric potential is then supplied to the electrically conductive wire by a control unit at the platform to operate the electrically operated function of the running tool to set the subsea wellhead component.

A method for performing a remote operation of a subsea wellhead, the method comprising:
- (a) providing a running tool having at least one electrically operated function and coupling a subsea wellhead component to the running tool;
- (b) coupling the running tool to a tubular string having at least one electrically conductive wire mounted within a tubular wall of the tubular string for transmitting electric potential to the running tool;
- (c) running the running tool and subsea wellhead component on the tubular string from a surface platform to a location within the subsea wellhead;
- then
- (d) performing the electrically operated function of the running tool using the transmission of electric potential through the at least one electrically conductive wire of the tubing string.
A subsea tool system for performing a remote operation in a subsea wellhead, the system comprising:
- a running tool having at least one electrically operated function for setting a subsea wellhead component coupled to the running tool;
- a tubular string coupled to the running tool, wherein the tubular string has at least one electrically conductive transmission line formed in a tubular wall of the tubular string;
- a control unit located on a surface platform, wherein the control unit is communicatively coupled to the transmission line to control the electric potential applied to the transmission line;
- and
- wherein the transmission line communicatively couples to the running tool to transmit electric potential between the running tool and the control unit to operate the electrically operated function of the running tool to set the subsea wellhead component.
