      The Darwin LNG Facility is the world’s first liquefaction facility to utilize high efficiency aeroderivative gas turbines for its refrigeration compressors. The plant’s design, startup, successful operation for over ...
    • Wagner, Norbert; Konig, Sven; Winkes, Georg; Sub, Stefan (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
      In this lecture a root cause analysis (RCA) is presented for a fatigue failure of a semi-open impeller of an integrally geared compressor. The compressor had been in service for about one year in an air separ 3rd stage impeller.
    • Mutasim, Zaher (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
      The performance and durability of industrial gas turbines are strongly dependent on the operating conditions and the environment in which they function at. Engine performance and durability must be equally considered ...
    • Zeidan, Fouad (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
      Bearings constitute one of the most critical components in turbo and rotating machinery today. Their influence on the rotordynamic performance, life, and reliability of the machine cannot be ignored. Many of the problems ...
    • Naldi, Lorenzo; Golebiowski, Mateusz; Borown, Adam (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
      This paper presents a summary of the authors' experience gained from implementation of model-based monitoring systems for LNG string vibration. The development of a novel train torsional vibration monitoring approach ...
    • Patel, Vinod; Kimmel, Hans (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2011)
      From the earliest days of gas liquefaction, the thermodynamic process advantage of employing cryogenic liquefied gas expanders in place of throttling valves was very well recognized. The available technology was unable ...
    • Schultheis, Steven; Lickteig, Charles; Parchewsky, Robert (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 ...
    • Bidaut, Yves; Baumann, Urs (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 ...
    • Forsthoffer, Michael (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 ...
