(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Scope of this Case Study is to apply a general approach used for Sub-Synchronous Torsional Interaction (SSTI) studies to a real Liquefied Natural Gas (LNG) plant, where severe SSTI events have been observed during commissioning ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)This presentation provides a success story that sub- synchronous vibration was eliminated on a centrifugal compressor. The sub-synchronous vibration originally occurred at high operational speed on this 5-stage hydrogen ...

-
(Texas A&M University. Turbomachinery Laboratories, 1991)In the past 10 years, there have been significant gains made in the repair of steam turbine rotors by the use of welding. This has been the result of improvements in several areas dealing with materials, engineering analysis, ...
-
(Turbomachinery Laboratory, Texas A&M University, 2011)Presentation and discussion of a unique magnetic coupling design that has been developed for cryogenic service in liquefied gases that allows the submerged motor or generator to be isolated from the process fluid in a safe, ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)As the offshore market faces deepwater production challenges, the oil and gas industry is investing in new technologies to bring down the costs in the subsea fields exploitation. A breakthrough technology solution is the ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Oil and gas production from offshore fields has been established since the second half of the last century. The continuous need and search for new fossil resources has driven the technology to adapt towards harsher and ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)The use of Subsea gas compression technology for subsea re-injection and/or gas transport boosting represents a new and exciting application for rotating equipment, which will allow new gas/condensate field production ...

-
(Texas A&M University. Gas Turbine Laboratories, 1978)In 1973 Aramco embarked on a large water flood projects for the Ghawar oil reservoir. After approximately 1 year in service three of the 16 X 16 X 20 2-stage DVMF pumps developed a severe shaft vibration of over 20 mils ...
-
(Texas A&M University. Turbomachinery Laboratories, 1987)The investigation of a subsynchronous vibration problem encountered in a six stage centrifugal compressor is discussed. At a running speed of approximately 9000 rpm, a subsynchronous vibration (at 4200 rpm) of nearly two ...
-
(Texas A&M University. Turbomachinery Laboratories, 1985)Subsynchronous vibration problems were experienced on two reactor charge pumps during on-site commissioning, which led to large whirl amplitudes, making the units automatically trip. A number of possible mechanisms of ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)In most natural gas applications, turboexpanders are operating close to or on the dew point line and a mixture entering the turboexpander impeller is a combination of liquid and gas phases of the natural gas. The presence ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)The importance of correlating rotordynamic analytical results to actual test data has become extremely important in recent years. Many user specifications require the verification of vendor generated analytical results in ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This historical case is focus on the vibration behavior of a generator. After a short circuit issue on the grid, the machine train trip. At this time the level of vibration of the generator was acceptable and well below ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)LNG production in the form of large land-based Mega-trains and floating production, storage and offloading facilities (FPSOs) have been of particular interest in recent years. The task of designing and building these ...
