    Abstract: A method of testing and monitoring operational integrity of a drilling rig is described. The method includes operating the drilling rig in a non-drilling mode at a sequence of different phases including an acceleration phase, a constant speed phase, and a decelerating phase, collecting sensor data associated with one or more components of the drilling rig while the drilling is operated in the non-drilling mode at the sequence of different phases, and analyzing the collected sensor data to determine the operational integrity of the drilling rig. The analyzed data, together with previously stored historical data is used to estimate the life expectancy of the rig and monitor, plan, control, or report maintenance activity for the drilling rig, top drive, or any other system.

    Abstract: A signal processing technique that decomposes complex, dynamically changing non-stationary signals from machine components such as bearings into different scales by means of a continuous wavelet transform. The envelope signal in each scale is then calculated from the modulus of the wavelet coefficients. Subsequently, Fourier transform is performed repetitively on the envelope of the signal at each scale, resulting in an “envelope spectrum” of the original signal at the various scales. The final output is a three-dimensional scale-frequency map that indicates the intensity and location of the defect-related frequency lines. The technique is generic in nature, and applicable not only to machine condition monitoring, but also to the health monitoring of a wide range of dynamic systems, including human beings.
