Abstract:
1. A system for running and setting a subsea wellhead component, comprising: a running tool having an upper end for coupling to a running string, the running tool adapted to carry and set the subsea wellhead component; an encoder positioned between the stem and the body to detect relative rotation between the stem and the body, the encoder comprising: an axial displacement sensor positioned between the piston and the body to detect relative axial motion between the piston and the body; a transmitter communicatively coupled to the encoder and the axial displacement sensor; a receptor communicatively coupled to the transmitter, the receptor adapted to be located at a surface platform; an operator interface device communicatively coupled to the receptor and adapted to be located on the surface platform; and wherein the encoder and the axial displacement sensor communicate information regarding the relative number of turns and displacement, respectively, to the transmitter, the transmitter communicates the information to the receptor, and the receptor communicates the information to the operator interface device.
