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.

is committed to accomplish this while reducing ...
STABILITY CONSIDERATIONS: A SIMPLIFIED APPROACH
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
In many cases it is necessary to judge the stability behavior
of a specific compressor. This might be the OEM checking the
feasibility of a proposed compressor layout or it might be the
user judging one of his machines ...
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 ...
