Simplified Modal Analysis for the Plant Machinery Engineer
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 6: Experimental modal analysis and operating deflection shapes (ODS) are powerful tools in vibration analysis and machinery troubleshooting. However, the machinery plant engineer often doesn’t believe such techniques ...
Enhancement of Pump/Plant Performance by Correct Evaluation of Process Fluid Viscosity Variations and Pump Geometry
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 16: In the modern pump industry, processed fluids are characterized by a wide spectrum of viscosity values. An unpredicted variation of actual process fluid properties, including viscosity, may lead to unexpected ...
Couplings - Balancing Tutorial & "New Developments in Gas Turbine Couplings"
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 15
Piping and Machinery Integrity on Structurally Resonant Platforms and FPSOs
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 11: Operators face significant integrity risks on offshore production facilities due to vibration of machinery and piping systems. These applications are more challenging than land-based systems because compressors, ...
Investigation of Process Gas Compressor Shaft Vibration Phenomena
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 13: This paper presents details of investigation results of issues observed during plant start‐up on a centrifugal compressor. Compressor was operated with air/ nitrogen during start‐up and high shaft vibration ...
Remaining Life Assessment of Steam Turbine and Hot Gas Expander Components
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 16: In today's market place, a large percentage of oil refinery, petrochemical, and power generation plants throughout the world have been trying to reduce their operation cost by extending the service life of ...
Field Evaluation of an Offshore Pumping System
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Technical Brief 5: An evaluation was performed on one of the largest offshore facilities belonging to PEMEX Exploration and Production due to forecasts predicting that future crude oil production will contain heavier oils. ...
Frequency Dependence of Piles' Dynamic Stiffness
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Technical Brief 6: The evaluation of the dynamic behavior of deep foundations for Turbomachinery Modules is not a simple task due to uncertainties in the evaluation of the soil shear modulus and the approximations introduced ...
Control Systems. Molecular Weight Compensation Consideration in Compressor Surge Control
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Tutorial 10B: The effects of gas molecular weight variation on a centrifugal compressor’s surge line and computation of the operating margin from surge for the purposes of antisurge control is discussed using different ...
Coupled Torsional and Lateral Analysis for the Determination of the Damping of the First Torsional Mode of Synchronous Motor Driven Compressor Trains
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 13: This paper deals with the damping ratio D (modal damping) of the 1st torsional mode of synchronous motor driven compressor trains. The damping ratio is a crucial parameter for the torsional start-up analysis ...
