Buying / Selling Serial #1
(Texas A&M University. Turbomachinery Laboratories, 2011)
The machinery utilized in the Oil and Gas Industry, (Upstream, Midstream and Downstream) is undergoing very significant changes. In the past years, the use of new designs or prototype machinery was strongly discouraged. ...
Operation Of Centrifugal Compressors In Choke Conditions
(Texas A&M University. Turbomachinery Laboratories, 2011)
Centrifugal compressors are at times required to operate in or near the choke region. Various limits of the degree of allowable operation in choke have been established. Based on test data and numerical data, the behavior ...
Range Vs. Efficiency—Striking The Proper Balance
(Texas A&M University. Turbomachinery Laboratories, 2011)
The paper addresses the balance between peak attainable efficiency and overall operating range that must be addressed when specifying, designing and/or selecting centrifugal compressors. The relative roles of the various ...
Stability Considerations - A Simplified Approach
(Texas A&M University. Turbomachinery Laboratories, 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 ...
Full Load Testing Of A 12.5 MW Vertical High Speed Subsea Motorcompressor
(Texas A&M University. Turbomachinery Laboratories, 2011)
In late 2006 Authors’ company was awarded a contract for the motorcompressor for the Ormen Lange Subsea Compression Pilot. This Pilot represents the first subsea motorcompressor unit ever built in a fully marinized version ...
Reliability Improvements On High Speed Reciprocating Compressors Through Bearing And Process Modifications - A Case Study
(Texas A&M University. Turbomachinery Laboratories, 2011)
Gear Box Failures Due To Bull Gear Slippage
(Texas A&M University. Turbomachinery Laboratories, 2010)
Bull gears slippage in speed multiplier of compressor trains occurred on two FPSOs offshore Brazil. These events produced high impact on the amount of flared gas and also in oil production. After being called, the supplier ...
