(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 14
High Vibration Problem Resolution in Centrifugal Pump through Design Change
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 4: The case study is about single stage API BB2 pump. Pump operates at the temperature of 355 degree C (671 degree F), rated for pumping 442 m3/hr of Hydro-treated VGO (Vacuum Gas Oil) and is driven by a steam ...
Case Study on Remote Diagnostics in Resolving Random Vibration on a Steam Turbine
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 7: This case study narrates an incident of random vibration spikes which occurred in year 2014 on one of the steam turbine bearings of a propane refrigeration compressor train. The random vibration spikes caused ...
Squeeze Film Dampers: An Experimental Appraisal of Their Dynamic Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 15: Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to ...
Meeting Compression Train Base Package Design Requirements for Service on Floating Production Storage and Offloading Vessels
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 6: Typical floating production, storage and offloading (FPSO) compression applications are presented, including drivers and auxiliary equipment, and typical compressor operating conditions. Base packages consisting ...
Investigation & Resolution on Oxination Feed Pump Pulsation Related fatigue failures
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 8: This case study presents the detailed analysis on the high pressure Triplex reciprocating pump. Issues were observed during the operation and subsequent detailed pulsation analysis was carried out to understand ...
Adapting Compression Equipment to Accommodate Declining Well Pressures and Ensure Overall Efficiency in Mid/Late Field Life
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 9: Compression systems are designed for the governing process conditions. In the Oil and Gas industry, these conditions are often dynamic and a function of reservoir or field characteristics which have varying ...
The Challenge for the Accurate Determination of the Axial Rotor Thrust in Centrifugal Compressors
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 11: The axial thrust is basically generated by a pressure imbalance across the impeller. The impeller is subjected to a great force trying to move it against the incoming flow. The cumulative thrust of all impellers ...
Structural Dynamic Behavior of Frame 9E GTG Module for LNG Plant
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 9: The traditional onshore installation of heavy duty gas turbine generator trains, especially for power >80MW, is stick built on heavy and rigid concrete block foundation. The challenge of modularization is that ...
