Abstract:
1. A system for running a subsea wellhead component from a surface platform, comprising: a running tool having an upper end for coupling to a running string lowered from the platform, the running tool adapted to carry and set the component in a subsea wellhead; a dynamometer stem having a bidirectional torque and weight sensor and adapted to be coupled inline to a lower end portion of the running string, and further coupled to the running tool, so that the dynamometer stem will measure an applied torque and weight at the running tool and produce a sensor signal in response, the dynamometer stem comprising: a receptor stem adapted to be coupled inline to an upper end portion of the running string above sea level; an acoustic receiver mounted to the receptor stem for receiving the acoustic signal from the acoustic transmitter; a radio frequency (RF) transmitter mounted to the receptor stem and electrically connected to the acoustic receiver for transmitting an RF signal that correlates with the acoustic signal received by the acoustic receiver; an RF receiver adapter to be located on the platform for receiving the RF signal from the RF transmitter; and a display connected with the RF receiver for displaying the signal in real time to an operator on the platform.
