The Road to a Fully Integrated Asset Management Strategy Applied to Rotating Equipment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Today most companies around the world are very much
aware of the benefits of improved plant reliability and
the elements necessary to achieve this, such as the
development and implementation of risk-based
equipment ...
DESIGN, MANUFACTURE, AND TEST CAMPAIGN OF THE WORLD’S LARGEST LNG REFRIGERATION COMPRESSOR STRINGS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Increasing demand for LNG has driven the
requirement for a significant increase in LNG plant capacity.
Qatargas II (QGII), a joint venture initiated by Qatar Petroleum,
is committed to accomplish this while reducing ...
HIGH FLOW PROTECTION FOR VARIABLE SPEED PUMPS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Low flow operation is a well-known cause of centrifugal pump failures and thus it is a custom to have low flow protection. On the other hand, protecting pumps from excessively high flow is usually not considered during ...
RCFA for Recurring Impeller Failures in a 4
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
A Root Cause Failure Analysis (RCFA) for repeated
impeller blade failures in a five stage centrifugal propane
compressor is described. The initial failure occurred in June
2007 with a large crack found in one blade on ...
Submerged Pumps and Expanders with Magnetic Coupling for Hazardous Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 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, ...
World’s First Aeroderivative Based LNG Liquefaction Plant – Design, Operational Experience and Debottlenecking
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The Darwin LNG Facility is the world’s first liquefaction
facility to utilize high efficiency aeroderivative gas turbines for
its refrigeration compressors. The plant’s design, startup,
successful operation for over ...
ON-SITE DETERMINATION OF THE CONTROL LINE FOR INTEGRALLY GEARED COMPRESSORS FOR AVOIDANCE OF IMPELLER FATIGUE FAILURES
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
In this lecture a root cause analysis (RCA) is presented for a fatigue failure of a semi-open impeller of an integrally geared compressor. The compressor had been in service for about one year in an air separ
3rd stage impeller.
GAS TURBINES DURABILITY IN HARSH ENVIRONMENTS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The performance and durability of industrial gas turbines are
strongly dependent on the operating conditions and the
environment in which they function at. Engine performance and
durability must be equally considered ...
NEW APPROACH TO TORSIONAL VIBRATION MONITORING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
This paper presents a summary of the authors' experience
gained from implementation of model-based monitoring
systems for LNG string vibration. The development of a novel
train torsional vibration monitoring approach ...
Fifteen Years of Field Experience in LNG Expander Technology
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
From the earliest days of gas liquefaction, the
thermodynamic process advantage of employing cryogenic
liquefied gas expanders in place of throttling valves was very
well recognized. The available technology was unable ...
