Combined Torsional And Electromechanical Analysis Of An Lng Compression Train With Variable Speed Drive System.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Nowadays variable speed drive systems (VSDS) are preferred to constant speed drives in the oil and gas industry because they can improve the efficiency of the process while avoiding the use of complex mechanical mechanisms ...
Practical Root Cause Analysis Of Connecting Rod Bushing Failures In A New Reciprocating Compressor And The Theory Behind The Failure Mechanism.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Seal Oil Piping Vibration On An Oil-Free Screw Compressor In An FPSO Application.
(Texas A&M University. Turbomachinery Laboratories, 2009)
A dry screw compressor skid was fabricated for offshore service that included oil buffered mechanical seals on the compressor. During shop testing, excessive seal oil piping vibration was observed that resulted in pipe ...
Successful Avoidance Of Major Secondary Damages Using Proximity Measurements To Detect A Partially Fractured Piston Rod.
(Texas A&M University. Turbomachinery Laboratories, 2009)
75mw Turbine-Generator Journal/Thrust Bearing Upgrade.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This case history discusses the upgrade of the #1 combination journal-thrust bearing assembly in the front standard of a 75 MW turbine/generator set. The existing taper land thrust plates experienced frequent failures and ...
Centrifugal Compressor Degradation Detection Through Remote Vibration Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 2009)
An example of availability gain using vibration remote monitoring systems for early diagnostic.
Aeroacoustic Phenomena In High Pressure Centrifugal Compressors - A Possible Root Cause For Impeller Failures.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the past decades studies of aeroacoustic phenomena in turbomachinery were mainly carried out by research institution. The aerospace industry was the main driver in this field since noise issues gained more and more ...
Development And Application Of A Vertical High Speed Motor-Compressor Simulator For Rotor Drop Onto Auxiliary Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the conceptual development of a subsea motor-compressor prototype running on active magnetic bearings, the emergency landing on the catcher bearings was identified as a potential technology gap. This is because the ...
Assessing Liquid Droplet Erosion Potential In Centrifugal Compressor Impellers.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This paper presents a method for estimating the potential for liquid droplet erosion in compression system components, such as the impeller of centrifugal compressors. The erosion model selected is used to calculate a ...
Diagnosis And Solution Of High Noise And Vibration Issues After A Propylene Refrigeration Compressor Rerate.
(Texas A&M University. Turbomachinery Laboratories, 2009)
