One of the power generation units had experienced intermittent high vibration at gearbox highspeed shaft drive end bearing, resulting in unit trips due to a sub-synchronous component. The sub-synchronous component was also present in lesser amplitudes on other operating equipment simultaneously.Two offshore facilities forming the upstream assets for LNG production are powered with six identical power generation units, with three units on each asset. One of the power generation units had experienced intermittent high vibration at gearbox highspeed shaft drive end bearing, resulting in unit trips due to a sub-synchronous component. The sub-synchronous component was also present in lesser amplitudes on other operating equipment simultaneously. This was identified as excitation of the 1 st torsional natural frequency (TNF) and further narrowed to an excitation source within the electrical grid. A systematic approach was taken to identify likely sources of excitation and isolate the source through data screening using event windows and operational testingItem IMPELLERS 301 : A Closer Look at the Heart of a Centrifugal Compressor(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2023) Sorokes, JamesThis tutorial is intended to build on the Compressor 101 and 201 short courses by providing a deeper dive into the factors that must be considered when designing centrifugal compressor impellersItem Design and Analysis of Large Induction Motors from a Mechanical Standpoint(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2023) Keck, Jim; Feese, TroyThis tutorial covers the following topics: Two-pole versus four-pole motors, Complications with two-pole having higher speed, uneven magnetic forces, variable speed operation, Review of American Petroleum Institute (API) 541 and 684 for rotordynamic analysis and shop testing, Difference between rigid rotor and flexible rotor, Lateral critical speed analysis, unbalanced response, bearing span, core stiffness, Finite Element Analysis (FEA) for structural analysis of frame and bearing housings, Shop mechanical run test, Impact testing, Operating deflection shape / modal analysis, How design and testing steps are implemented throughout the manufacturing and acceptance processItem Methods for Minimizing Energy Consumption for Parallel and Series operation of Compressor Trains(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2023) Staroselsky, Serge; Jacobson, WayneThis paper formulates the optimization problem in terms of minimizing the power consumption of the trains, given the constraints posed by the external process requirements, such as mass flow delivered to the process at a given pressure ratio, and the limitations imposed by the operating envelope of the unitItem Centrifugal Compressor Noise Generation, Prediction and Mitigation(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2023) Liu, Zheji; Price, StephenCentrifugal compressors used in oil and gas applications can produce strong pressure pulsations, piping vibration, and noise due to their high power density.Item Coupling Selection Guidelines for Rotating Equipment in the API Industry(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2023) Maier, Martin; Sakers, Chuck; Hanaka, Scott; Fitzgerald, Carry; Naumann, Andreas; Krause, TimCouplings are typically sized based on Driver Rated Torque and driven equipment Normal Torque.
