Managed Pressure Drilling (MPD) is a technology that allows for precise wellbore pressure control, especially in formations with uncertain geomechanics. The Rotating Control Device (RCD) is a crucial part of the MPD equipment but is prone to failure. Therefore, a new condition monitoring system was developed to improve the reliability of RCDs and eliminate their catastrophic failures during MPD jobs. Non-intrusive sensors were selected during the design of this condition monitoring system. Sensors measure: vibrations, acoustic emissions, rotation, pipe movement, temperatures, and contamination level in the coolant fluid. The system can display the measurements in real-time to the operator, giving early warnings to prevent the RCD's catastrophic failures during the job. Additionally, the data is recorded to allow further processing and analysis using ML and AI techniques.

Analysis of vibrations generated by the multi-body model of a planetary gear
(2012) Dąbrowski, Dariusz; Adamczyk, Jan
In the paper the dynamic model of an one-stage planetary gear was presented. The model was developed on the basis of a multi-body dynamics method. To conduct dynamic simulations the specialized multi-body dynamics software was used. In the study the tests results for steady state operations of the planetary gear were presented. In the paper the meshing force signals were analyzed. The vibrations generated by the model consist of carrier and gear meshing frequency harmonics. On the spectra the amplitude modulations of the gear meshing frequencies harmonics were observed.
