Catastrophic Failure Diagnosis with Modal Analysis of Generator Endwindings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This failure lead a root cause analysis and a series of investigations that was taken place in a similar design unit deployed at a different site. This paper will describe the bump test and modal analysis procedures and ...
Couplings and Rotating Machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course covers the design and application of high performance couplings and
rotating machines. Initially the Turbomachinery driver and driven machines are
analysed together with their characteristics and how they affect ...
Case Study on Resolving High Vibration Issue of a Centrifugal Compressor at an Offshore Platform
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Gas Injection Compressors are critical for offshore oil production facilities. A compressor downtime lowers oil production. This case study is about a Gas Injection Compression train at an offshore platform in the Middle ...
Save your Centrifugal Machinery during Commissioning
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During the commissioning of centrifugal machines (Compressors, steam turbines, pumps, fans etc.), a lack of flushing, inspection and ignorance of critical areas & procedures can lead to major problems, damage, and serious ...
A Fresh Look at Containment Seals and Equipment
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The need for reliable and safe sealing of rotating equipment remains as a primary concern for industry. In situations where single mechanical seals were used the introduction of environmental and safety legislation brought ...
Metallurgical Failure Analysis of Steam Turbine, Compressor, and Hot Gas Expander Components
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
When components fail it is usually unexpected and the root cause is not always known. Downtime from failure can cost a company many thousands of dollars a day depending on the type of equipment. This cost can be magnified ...
Digitalisation in Medium Voltage Variable Speed Drive Systems to increase productivity in O&G applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In this paper we talk about influence of digitalization in process industries and how it can be adapted to Medium Voltage drive systems. Various aspects of digitalization like monitoring, preventive maintenance and using ...
Dry Gas Seal Contamination During Operation and Pressurized Hold Background and Potential Solutions
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This paper will discuss the challenges with contamination of gas seals. The reliability of gas seals is largely dependent on having a continuous supply of clean and dry seal gas. In dynamic mode, gas supply systems take ...
Large Cooling Water Pump Upgrade for Increased Capacity And Reduced Impeller Cavitation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study discusses the hydraulic upgrade of two sets of four (25 percent) large vertical cooling water pumps. To increase the electrical output of subject power station, the cooling water pumps of block 1 and 2 had ...
