RECIPROCATING COMPRESSOR CONDITION MONITORING
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Technology for reciprocating compressor condition monitoring has been around since the 1950’s, however until the last 20 years or so it seemed that only the pipeline companies spent much effort on this activity. Technology ...
Large Vibrations on a Centrifugal Compressor Caused by High Windage Heating on a Flexible Coupling–Root Cause Analysis and Solutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
Background: 2 parallel trains consisting of a Low Pressure (LPC) and High Pressure (HPC) compressors were supplied for an offshore reinjection application near the coast of Angola. During the commissioning on site large ...
Seal Condition Monitoring Principles
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
As many of you have experienced throughout your career, Mechanical Seals are the number 1 failed component within pumps. So, how do we fix that? In this tutorial, we will discuss why seals are the # 1 failed component, but ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
LNG TURBOMACHINERY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The International Liquefied Natural Gas (LNG) trade is
expanding rapidly. Projects are being proposed worldwide to
meet the industry forecasted growth rate of 12% by the end of
the decade. LNG train designs in the coming ...
VSDS Motor Inverter Design Concept for Compressor Trains avoiding Interharmonics in Operating Speed Range
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
During operation of compressor trains by a variable speed
drive system (VSDS), integer and non-integer harmonic
currents are generated in the inverter. Via the electrical system
of the inverter and the motor, an excitation ...
IMPACT OF ELECTRICAL NOISE ON THE TORSIONAL RESPONSE OF VFD COMPRESSOR TRAINS
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
The popularity of VFD motors in compressor trains
has increased in recent years. Increased process flexibility is a
primary consideration for implementation of VFD systems.
However, this comes at a cost of increased ...
ENHANCING OIL PLATFORM AVAILABILITY AND RELIABILITY
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
As part of the Upgrade project of 1998/99 the Main Oil line (MOL) pumps were replaced with smaller pumps from NUOVA PIGNONE (NP), due to Three-phase separation. The new pumps were installed with John Crane (JC) Double ...
