Abstract: In accordance with an embodiment of the disclosure, a method includes detecting a first parameter indicative of lateral movement of a top drive system with respect to a rotational axis of the top drive system with a first plurality of sensors and detecting a second parameter indicative of lateral movement of the top drive system with respect to the longitudinal axis of the top drive system with a second plurality of sensors. The first parameter is different from the second parameter. The method also includes transmitting the first parameter and the second parameter to a monitoring system and comparing the first parameter to a first threshold value and comparing the second parameter to a second threshold value with the monitoring system. Detecting the first parameter and the second parameter includes detecting lateral movement of a mud saver valve configured to flow mud through a sealed passage.
